    This worked perfectly and was extremely accurate.
    We had recently had our caravan serviced and was told that our caravan was letting in some slight water.
    They had done a damp meter test with a high end professional damp meter.
    Although we had no doubts about the integrity of the caravan service department, we thought it would be a good idea to have one of our own in order to keep an eye on the situation ourselves after the problem was remedied.
    This damp meter was spot on accurate, giving exactly the same results percentage as the service dept.
    Highly recommended for those who want professional accuracy at a very low price.

    I bought this dampmeter recently after we had some building work done recently. There was some white stuff on the outside of the new plaster and I suspected that there was some damp because the work hadn't been done properly.

    So, to check this out I ordered this dampmeter. It is very light and requires a 9v battery. There are two buttons on the side, one to check that the battery is working and the other to use when you are testing for damp. In this case you just throw the second switch and press the two metal pins on the wall you wish to test. The meter indicates a percentage damp and there are 3 colour-coded regions. Green indicates normal (< 10% to 16%), Yellow indicates attention required (16 - 20%) and red indicates Action required (20-28%).

    For the wall I needed to test, most of it was fine, although there was a small patch that was at the top end of the yellow scale. I also used it to test the cellar. There were some damp patches here as well.

    This is a very useful tool to have to test the state of your own house, as you can probably find out where the water is coming in. I t is also particularly useful if you are thinking of buying a property, as you can easily test for dampness within a few minutes around all those places where dampness is likely. at under £15 it is reasonably cheap and well worth the money.

    Good litle meter for testing damp. Ideal for personal use, probably not robust enough for builders. We are going to buy a second one for our property business.

    Excellent product, got this to test 'buy to let' property. Really does the job at a quarter of the cost of a semi pro meter. Made a protective cover from an old MP3 player in case I dropped it.
    I would highly recommend this product.

    This is a product that 'does what it says on the tin'. It is simple and easy to use, with clear indication of results. Much more effective than a buzzer as it shows the degree of dampness on a scale of 0 -10 as well as low medium and high colour warnings levels.

    Needed something to check if my handy work had solved the problem of water getting under the roofing felt of our extension and onto the ceiling. Read some of the other reviews about this product and decided to give it a try. I was not dissapointed. It worked a treat and proved my ceiling was in fact quite dry again. I tried the meter on different surfaces to prove it was actually working properly and it gave readings which were in line with expectations. It may not give detailed or accurate readings that would be expected on more expensive meters, but if you need something to tell you if it is dry, damp or sopping! this will do the job and for the money is extremely good value. On the basis that if you do find a damp problem you are likely to call the professionals in and they are the ones that can use the expensive meters. This meter can give you the peace of mind you are looking for at a very reasonable price. It may be quite lightweight in construction, but how many times a week/month/year is the typical DIY'er going to use it? If you do need something to use more regularly, may I suggest you give up DIY!

    Bought this as we had a blister appear on our laminate floor and were concerned it might be damp underneath. Tried it and to our relief it didnt show any damp at all. Tried it on a wall we were concerned about and it did read damp there, so generally were happy with it (and were happy it worked). However, we then got a damp expert out who turned up with his own (no doubt super expensive industrial) damp meter and that picked up lots of damp where the blister was and generally on other parts of the floor. Investigation revealed a 4m by 3m area of black soggy floorboards under the laminate due to pipe bursting under floorboards. I would have been hopeful that this damp meter might have given some indication of that, but having said that it is pretty cheap, and I'm not sure how difficult it is to read damp through laminate, so I wouldnt want to give it a bad review. I think its fine as long as you're testing straightforward materials (plasterboard, wood, etc), but if you're worried about laminate, spend more money on a more effective damp meter or hire an expert!

    I was selling my house and concerned about damp in certain areas so wanted a heads up before a surveyor came round. I bought this to test where I thought the damp was and it didn't let me down at all. Some areas went to "red" straight away but some areas where I thought there may be damp showed up as being okay. It was very reassuring to know that there wasn't as much damp in my house as I thought that there was. The product was extremely easy to use and understand and would thoroughly recommend it.
