    I bought one of these (eBay item 271480282965) a few weeks ago. Took a while to come from China but seems to work OK and doesn't leave holes.

    Looking at eBay records I ordered it on 29 September and it was due to arrive between 8th & 20th October. eBay no longer gives actual dates for when feedback was left but I left feedback on the day of delivery and it was more than a month ago so it must have been closer to the 8th than the 20th.

    Terry sent me one a few days before I went to Germany to buy my motorhome, and I must say that this little gadget works really well to see where it is damp or not!!

    I love it and keep it in the van to check each time I think about it. The one I have has a scale saying how damp it is . If it stays around 15 it's a bit damp but not desperate , mine is going from 2 to 13/14 in the wet places such as under the shutter in the kitchen or under the kitchen sink.
    Mind you I have as well a quite good sense of smell , and if there is any damp I can smell straight away . Unfortunately , this part of my body is not to be sold:D

    In my experience a moisture meter or damp meter is used to measure the surface moisture and cannot determine the amount of moisture within a material overall. Even the meters with probes can only measure the moisture at that point.
    If the moisture meter is being used to measure the dampness on the surface of a wall or ceiling of a motorhome and does record that dampness is present then the ingress of moisture to that point is likely to stem from the roof or outside wall and by the time it reaches the surface, where the reading is being taken the damage is most likely already done and a search will be needed to investigate the source ie the seals on the roof, windows etc.
    It is also possible that the moisture on the wall or ceiling may possibly be condensation rather than penetrative damp.
    Use the meters by all means but be aware of what the readings are indicating.
    I hope my views are useful and based on experience.

    Certainly - and I agree that they are only an indicator.

    The engineer doing our habitation service last January found isolated high readings which he/we traced to cracked sealant and he was able to repair it pretty easily and cheaply. Without the check we would probably not have known until later, when repair would be more expensive.

    I bought my meter so that I could do spot checks from time to time in between habitation services, just to keep an eye on things.

    Funnily enough there were pin prick holes all round the window - guess they must have known our van had a leak when it was new

    If you used a damp meter what would the reading tell you?
    We use our damp meter to test the water content of logs that we cut. Freshly cut trees can have a moisture content of 50%, and we season it until it's about 15%
    What reading would tell you your van is damp or dry?

    Have had one of these types for many years now and regard it as an essential piece of kit. Yes it leaves 4 pin holes as I do go well into the board but try to locate test areas in places where the "damage" is minimal - behind curtains, upholstery etc. Roof light; don#t really care as I feel it a good trade off - damage against damp detection. No one to this day has ever commented on the tiny holes around the roof light.

    Readings; personally I take readings throughout the year and record the results. I then compare as some meters will give higher readings higher than others. It's the variation I scrutinise not the actual reading if you see my logic.

    At one location (lets keep with the roof light) I usually get the following at 4 points:

    Summer - 12%
    Winter - 18%

    This I feel is down to increased humidity and the colder climate. Anything above this would warrant further investigation.

    I just rip all the internal panels off. No need for a meter. No panels left on inside of Motorhome now so dead easy to check !
