    5.0 out of 5 stars Excellent product 22 Jun 2009

    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.

    5.0 out of 5 stars Simple to use and useful 24 Aug 2009
    Verified Purchase
    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.

    4.0 out of 5 stars Rapitest Damp Test Meter 23 Oct 2004
    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.

    5.0 out of 5 stars RAPITEST-DAMP TEST METER 8 Feb 2009
    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.

    4.0 out of 5 stars this is the one to consider 18 Dec 2009
    By DIY boy
    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.

    5.0 out of 5 stars Damp Test 11 May 2009
    Rapitest - Damp Test Meter
    I have recently been house hunting and looking at old cottages. As this type of building is prone to damp problems I took this little instrument with me when viewing properties. It saved money on expensive damp surveys and helped me to decide weather to commit to buy somewhere that would require expensive damp treatment.
    So well done Little Damp Meter. 10/10

    4.0 out of 5 stars Excellent Buy!! 13 Sep 2010
    This product has done all that I expected. I bought it to check for the location of damp in our caravan - I knew it was damp in some places but wanted to get a better idea of how far the damage had spread. This Meter confirmed the worst places, identified places I did not suspect and confirmed the limit of the damage. I decided to attempt the repairs myself and the Meter has proved to be correct in that I have been able to limit my remedial work to the required locations. The two prong probe is at the end of an extending cable - this makes it easy to push the prongs into tight corners and still read the Meter. I find the needle/scale reading to be easy to understand rather than to guess the frequency of bleeps from an audible unit. In use you need to ensure that you do not get false readings from hidden nails or other conductive materials. Very pleased - would have given 5 stars if the illustration had shown the probe and cable that comes with this Meter. Remember to buy a battery!!

    I chose a rating of 2 as I don't feel the item represents value for money it is flimsy and varies each time you use it I wish I had opted for a more expensive one.
