Cheap and easy remote probe damp meter for Motorhome or Caravan under £25

We've had a small damp area in our van, and original dealer struggled to resolve, so bought a cheap £5 damp meter to check our motorhome regularly, but its awkward to read in corners and cupboards, so I wanted something better.
There are some very expensive motorhome damp meters around, but I found this cheap meter with long probes for under £25 which is easy to cut the probes down to make a really handy damp meter for motorhome or caravan.
I bought this on ebay from hong kong which came in just over a week, but they are similar prices on amazon, and if you want UK postage for a few pounds more there are ebay UK sellers.
Hope this is useful info, when checking your van check round windows/apertures, and along the edges/seams of walls and ceiling, normal readings vary depending on weather etc so anything under around 15% is probably fine, you are looking for any area's which have higher readings than the average, and those will need looking at.
We ended up going to another dealer to get our initial damp sorted which they located in about 30 seconds, and fixed in a few days, and have had a couple more area's resealed since, both were completed in a couple of days with exterior resealing only and the inside dries out over the next few months, so if you keep on top of readings, then its nothing to worry much about.
Hope this is useful info.

I was wondering if it is necessary to stick the probes in the wall of the caravan to check it? is it ok just to put the probes in touch with the wall surface or is not enough?
thanks in advance!!!

You need to push probe into wall, otherwise you are just checking surface which should be dry always anyway. You can get contactless testers which give a rough idea, so can use for a quick sweep and then check specific area's with probe tester.

I am wondering if it is necessary to cut them at all?

[@jamesb72]

The prongs are not quite pointy enough and quite unwieldy due to length otherwise, so if you are going to change shape of tips, its just as easy to cut them down at same time I think.
