I ran some basic tests on the hygrometers to see if the linear scaling would be a problem. A link at the end takes you to a Twitter thread with pictures. The result was... mixed. It seems clear that the high end humidities are never attainable on the Taylor model nor the clock. They don't seem capable of reading past 80%. However, on the low end they were in better agreement with the other models.
It may be that the linear-scale hygrometers are built so that they behave more linearly but I'm personally doubtful of that. I would personally avoid dial-hygrometers with linear scales.

Hello there! 🌈
I have no clue what you're talking about. Huh.. guess it's easier when you say it out loud to us.
Could you do a video on how water softeners soften water? I think I looked at 20 different diagrams and I still don't understand how the water doesn't get salty or how the limescale soaks into the salt
I use a Fischer hygrometer at home. It is linear and quite accurate.
Is that the same 'Taylor' as in the new McDonalds soft ice cream expose' ?
How about those cheap digital hygrometers?

*CED playlist card pops up*
I think this is the only channel on CZcams that uses that corner card as a comedic punchline.
And his heat pump video (1st) had so many references he made my favorite joke with the "Another plug?" as he pulled an extension cord into view
The CED videos killed me.
Not literally... but it was the last video I watched before I died.
But unlike CED, they brought me back from the dead.
Alec even made the background tv’s various pictures of RCA and CED stuff. Well done trolling.

Sucked in by the junk shop twice.
"Through the magic of buying two of them" will never get old for me, even if you try to just casually sneak it by without emphasis this time.
The panning closeup shot at 0:33 could straight up be out of an "how it's made" episode.
I thought I was the only one that thought the same for most of his episodes
I was legit just thinking this channel is like How It's Made but really How It Works, then I saw this comment.
True
thats not a pan thats a tilt
"sorry, this is a tangent now"
I fucking love it lol
Whenever someone says "bimetallic", I never know whether they mean "twice a metal" or "once every other metal".
This comment really made me laugh and agree at the same time.
Yes.
Well, the solution is in the wards itself, bi means two, nothing else, biannual is two + yearly (annual means yearly, or every year), so the two mean every two year mettalic means made of a metal, so bimetallic means made of two metal
Clearly bimetallic is 'two metals', otherwise it'd be fortmetallic to be 'once every other metal', duh! :P
That's why you should use "fortnickelly"!
“This website I found...”
and it’s Wikipedia .
Thanks for the tremendous laugh, that was neat!
its always wikipidea
Wikipedia is tight
Good tie-in to his search engine rant lol.
Not the first time he's made that joke. But I can remember exactly which other video he used it in.
Blatant product placement.
I just wanna say that the shot at 0:33 (a common framing on this channel), reminds me soooo much of “how it’s made” and i love it
I thought the same!
Damn, that's a perfect parallel. They are the same framing and motion, and you know what? It's probably one of the many little things that make both so fun to watch.
As a child in the 1950s, I read about what was considered the “gold standard” of humidity for use by professional meteorologists, the wet-bulb dry-bulb hygrometer. This consisted of two well calibrated mercury thermometers mounted side by side on a board, with the mercury bulbs hanging off one end. One of the thermometers had an uncovered (dry) bulb (perhaps protected by a metal screen), while the other was wrapped in a small piece of cloth, like a shoelace. The meteorologist would soak the cloth around the dry bulb in water, then use a cord attached to the other end of the board to swing the board around in a circle for a prescribed amount of time, in a shaded and rain-protected outdoor shack. Then they would take both readings and look them up in a table, giving the relative humidity.
Today they probably have two thermocouples mounted on a centrifuge and a microprocessor does the table lookup.
The wet bulb registers the dew point - a temperature based way to represent the absolute humidity. The chart would cross reference the dew point opposite the ambient temperature (which puts a hard limit on maximum absolute humidity) and the intersection would be a percentage of actual to maximum absolute humidity - or the relative humidity.
A "sling psychrometer"
wet bulb is not actually used any more? good grief why doesn’t the news report on things such as this. i’m just a lowly physicist with basic knowledge of the world.
@@shibasurfingyou can make hugrometers without needing a temperature sensor at all, there are materials that react strongly to the change in humidity and you can use them to change capacitance or resistance to pretty precise numbers. At least as precise as a thermistor, dunno about a thermocouple
@@shibasurfingwhich is why OP acknowledged that they probably use thermocouples now? For a physicist your reading comprehension is pretty dogshit.

CZcams creators can find tons of free music to use in their videos that doesn’t require a license fee to use. As to why he left it out this time I think it was so he could label this as a truly simple quickie video.
In Spain we have some pretty interesting old hygrometers, we call them "fraile del tiempo" or weather friar. It's a cardboard image of a monk, usualy sitting on a study, with an articulated arm and hood.
The arm moves reacting to air preassure and humidity and points towards different weather predictions, and when it points towards rain the hood pops up.
These remarkable and mystifying little devices prove really simple when you turn them around, as they are moved by a single strand of horse hair.
Fíjate... No tenía ni idea. Gracias!
Nunca he visto uno, pero suena como el dispositivo ideal para explirar en este canal jaja
My dad made a hygrometer using human hair that hung in his shop. It was a bike spoke, attached to a circular piece he turned on the lathe. The hair was stretched from the top and wrapped around the aluminum piece at the bottom which was on a bearing, and the spoke was slightly off center of its center of gravity and provided the tension. It was also the pointer. He would occasionally ask my my mom for one of her hairs, if the hair needed to be replaced. It worked pretty well.
love the idea of devices made from human body parts

The one case in which a CZcamsr went *below* 10 minutes on purpose. What a time to be alive.
Well last summer CZcams lowered the mid roll ad qualifying video time from 10 minutes to 8
I see someone's been watching Two Minute Papers as well 😂
"What a time to be alive" is the catchphrase from that channel, after all!
EDIT: I see now that the reason I keep getting replies is because the word "the". To clarify:
① There is a well known English phrase: "What a time to be alive".
② The "Two Minute Papers" CZcams channel host Károly Zsolnai-Fehér says this phrase very often.
③ Károly Zsolnai-Fehér did not make this phrase. Its use predates 1994, and was seemingly popularized by a Simpsons Episode from 1998.

@@PhotonCrasher I'm not sure where "what a time to be alive!" originated, but another place it was popularized was on a Simpsons episode from 1998. (I had to look it up, never watched Simpsons but I saw the meme)
I'd like to think it was quoted from Two Minute Papers, though.
I still remember when it was impossible to upload a video greater than 10 minutes. lol.
Cool video, thanks. Few years ago I learned something very interesting about how they measure air humidity at airports. For the flight operations it's more important to know at which point pilots need to expect fog, clouds or icing. Because of this they give the humidity by telling you dew point (temperture at which the water will condense). You can calculate the dew point from relative humidity, but often the dew point is directly measured by cooling a mirror until you see condensing water. I think this is a strange way to measure humidity :-)
Dew point is interesting very much more relevant/critical. Especially if you live in areas of moderate climate. I have (or am working on ) a logic controller for my HRV unit - which normally serves to remove humidity in winter, but which I use to remove CO2 in summer. The logic will check the outside dew point, and if it is greater than 10C, it will reconsider running the unit since a dew point > 10C will result in an indoor relative humidity > 50% which is not what I want.
Or dry bulb and wet bulb like inlearnt at shcool
In college, we used a "wet bulb thermometer" (a thermometer with a damp little cotton sock on the end), that you spin around in the air for awhile, then read the temperature. Then you compare that with the dry temperature, and use some equation which I don't remember to get the relative humidity.

I just wanted to say I discovered your channel two weeks ago and I've been watching all of your videos, everyday I learn something new. I absolutely love it. Keep up the good work. I couldn't be more subscribed.
I'm going to keep complaining until we all start using Kelvins for temperature
We don't even need "temperature" units. Just apply Boltzmann constant to all of them.
I occasionally say to my friends: "Oh, boy! It's hot today, over 300 degrees!"
why would we do that, when the Rankine scale exists?
@@AkademiaFlirtu Kelvin is NOT any kind of "degree" it is Kelvin or K in short, it is temperature unit, so you would not say "300 degrees" you would say "300 kelvin"

You were not kidding about the stats tanking. I appreciate you making it anyway even knowing that.
I really enjoy your content, big and small.
I found from your toasters and have been hooked since. I kind of like that I found you late just because it means you already had so many videos that I always have a few to watch. Which is great, because I really like watching several in the same day.
Thank you for all the amazing content. I have learned so much researching further into a lot of the things you’ve talked about. 💜🐿
A really good approximation that works well in normal temperature atmospheric temperature ranges and is easier to calculate is F = 2C + 30 or C = (F-30)/2. It's not exact of course, but is much easier to do the math in your head, and gives you a good feeling if you are used to one unit system vs another.
My uncle who fled to Canada in the 80s after a…”snow storm in southern South Carolina…” uses that, I’m pretty sure, on the rare occasion I see him and temperature is brought up in conversation.

"This is actually a bimetalic strip tease"
Youuuuuuu
Love the shirt. I had instant flashback to bookshelf in our living room in the 80s filled with VHS tapes recorded over dozens and dozens of times.
As I age I realize that my joints: elbows, ankles, knees, wrists... Are as accurate as a metal strip tease device at measuring humidity.
What I'd like to know is... How does the humidity get into the joints, and how is the accuracy not completely destroyed by all the water-based fluids already in there? It's not like a hygrometer works from inside a water tank
@@nthgth My guess is that our joints are barometers rather than hygrometers. I live in a very dry part of the country and a storm will come in and I'll feel like crap. But the humidity at the ground doesn't change much.
@@nthgth the joints have some fluids in them, which is by need balanced with the outside environment, and the movement of your bones inside that fluid makes it bubbly, producing lots of tiny bubbles, the bubbles collapse, and generate a small "explosion", when you crack your fingers or whatever, these bubbles what you hear. These explosions are giving you lots of data to the very sensitive receptors inside your body, and in time you learn to compare the data to useful information, like humidity, temperature, weather forecast and so on.
@@christophers.8553
Exactly right. I have bad arthritis in my shoulder after 10 operations and I can always tell within 24hrs if it's going to rain with about 80% reliability.
I started to notice pain in my shoulder was relative to barometric pressure either rising or falling as I have a barometer in my watch.
As the shoulder (and other joints) are a sealed fluid filled cavity it makes sense that atmosphere pressure can cause those joints to expand or contract causing pain.
Yes to simplicity, yes to turn-y things, yes to jokes.
We're here for all of it.
Also, these videos have given me the additional benefit of realizing that I have been calling something by the wrong name for a long time.
My grandfather was a Special Agent in the Alcohol, Tobacco, and Tax service (as it was then named) back in the 30s and 40s.
While most of the stories we heard about were from his time during prohibition, a great deal of what he and the others did was enforce basic regulatory things such as proof standards for distilled liquor.
We still have some of his tools and accessories... including the lead shot filled long glass instruments that would use specific gravity to measure alcohol content. I had long referred to these as hygrometers and only now when googling did I realize they are actually called hydrometers.

Love the videos...keep them up. As a physician I got used to using both F and C and both lbs and kgs. I could convert them with sufficient accuracy in my head. The only gripe I had was that between freezing and boiling in F there are 180 degrees and C of course has 100. When doing body temps, one was always having to use decimals. The degrees are "fat" so you had to get an impression in your head that 38.3, which is only a bit over 1 degree is 101 in F. Which is nearly 2½ degrees F and a significant fever. I trust that the younger physicians are more mentally comfortable with it. Of course.... I came along at a time when older guys will still calling for 1/8 grain morphine in the ER. Try converting that in your head!

@@tanya5322 But it IS odd. Because that area was only ever "west" OR "mid" at any one time... sure, it was "the northwest" when the eastern seaboard was all else... but when the west expanded out to the western seaboard, it was no longer west, it was mid... I get there's a little bit of, ahem, history in the way of just being "the north"... but "central states" works just fine, no?
East, Mid West, West is as silly as if South Dakota split into two states and named themselves Mid South Dakota and South Dakota :P
Of course, then the state of Mid South Dakota located in the Mid West region of the country that claims the name United States of America despite it not at all including every state on either continent bearing the name America... would confuse some Eldritch being into thinking an ancient prophecy had been fulfilled. It's just that silly :P
@@damien4197 The midwest was named as such because America acquired land to the west and intended to colonize it, but the majority of the population existed in the "normal" part of America (now called the east coast). The midwest was easily accessible barring the part of it being pretty far from everything, which is still much easier than getting over the giant rocky mountains in order to get to the real west. The stories of how the west coast and midwest were colonized are different, the people that were sent to colonize them were different (for instance, until the world wars, the primary language spoken in your average household in Nebraska was a German or Scandinavian dialect, not English). All of this from the perspective of the East Coast. America didn't have any major cultural centers outside of the East Coast until Hollywood came along, so the historical memory of America in those days was written by people in places like New York and South Carolina.

I appreciated the snark regarding temperature scales and the ease of being able to covert readings using most internet search tools. :)
In Finland we regularly go from a room heated to 100 degrees C and jump into hole cut into a frozen lake (0 degrees C). So the celsius scale is actually quite appropriate to measure comfortable ambient temperatures.
It all depends on what you're used to using.
Heating a room up to 100°C is quite an achievement, unless it happens to be a walk-in oven (that would be 212°F). I’ve know those that would do a Polar Bear run from a 100°F (37.8°C) to a 0°F (-17.8°C) winter day… Blessings to them…

You are the best science teacher that none of us ever had.
Love your shirt. I used that tape to record all my favorite shows back in the 80's.
You're a wizard, man. You cast "Buying Two Of Them" so often.
Last time I was this early I was uneducated about brown.
You mean ORANGE!!!!
0-100 is a hot day scale for you . 0-100 is a ice block to boiled water for us . lol great vid :)
The specific glance before "I don't want..." at 2:45 is my new favourite. - From a Celsius-lover.
A how-it-feels celcius poem:
_30 is hot_
_20 is nice_
_10 is cold_
_0 is ice_
A how-it-feels Fahrenheit poem:
_32 is cold as ice_
_but halfway up the scale is nice_
_three quarters up is getting warm_
_over a hundred can do you harm_
_going down the other way_
_one quarter up is a brisk day_
_below zero you should use caution_
_wear a coat or freeze your bottom_
30-40 🥵
20-30 😎
10-20 🙂
0-10 😑
-10-0 🥶
< -10 🧊
Kelvin or bust!
That sounds more like a four star rating system, not a temperature scale.
@@Sunlight91 Notice how that scale doesn't get up to 100 and drops significantly below 0.
If only there were some alternative where the weather fit more between 0 and 100...
Loved the "this website I found" hahah
Anyone else noticing how his hair has been slowly but surely growing from one video to the next?
We have. And it looks great! But Alec usually looks great, so that's no real surprise. The longer hair goes with his 'work uniform' in a way I wouldn't have anticipated when it was shorter. It's a great look for him! I hope his 'everyday' look is similar to his work clothes, because it works really well for him. 😊 But even if the longer hair is just a covid thing & the shorter hair makes a summer return, he'll still look fantastic, so it's all good.
It's for the follow up-video where he'll transform himself into a hygrometer.
he can't find the switch to stop it growing.
He’s obviously planning to start a hygrometer factory.
As both a career engineer and an indoor grower, I discovered to my chagrin that measurement of RH is one of the last frontiers of instrumentation. Consider the precision and accuracy with which we can measure infinitessimal amounts of time, or voltage, or wavelengths of light... GAH! ±5% is literally outstanding performance, and it's what the plastic-element units promise but do not, in the field, deliver, and their range is smaller than the range of a classic hair-containing aneroid. What I found was that, for the money, the best accuracy-vs-money deal are european (I think they were German or Swiss - figures) aneroid hygrometers - about $200, which have subsequently been NIST-traceable calibrated in a chamber, making them $250 or $300. The only way to do better is to use a chilled-mirror instrument, which are generally suitable only for lab settings. :/
Hello. What's the accuraccy of those? I am looking for a small hygrometer (to fit in a small fridge) that can be accurate to +- 0.1% for my cigars, but as you said it seems that +- 2-3% is the most precise we go
"I'm going on a tangent"
*Proceeds to spend half the video going on a tangent about F to c conversation*
I'm all here for it.
My dad has been a weather "nerd" for a very long time, as well as having an appreciation for old tools. One of his favorite finds was a wet bulb hygrometer. It is 2 mercury thermometers, where the bulb of one is kept wet by the capillary action of a cotton wick that has one end in a long "J" shaped glass tube (modern ones seem to just have a small horizontal reservoir). That tube gets filled with water, and then the *latent heat* of evaporation causes the wet-bulb thermometer to read a lower temperature. You can then look up the relative humidity on a chart - which is distinctly non-linear. It's not super practical because you need to fill the tube every couple days, but it is supposed to be very accurate.
Your little side rant about the inanity of the great C/F wars made my day. Some of us use the metric system, some of us don't, get over it! When I watch European TV (or CZcams videos from overseas, for that matter), I don't expect them to provide imperial unit conversions for everything. Why can't we just embrace our differences?
Without music and credits?? I feel like I'm not finished watching. Honestly I couldn't be sure I just watch something from Technology Connections were it not for the whole linear scaling, Farinheight > Celsius search engine tangent, the sett...well everything really! Keep up the good work man, I LIVE your channel!!
