## Description

Extech MO55 Combination Pin/Pinless Moisture Meter, Green : desertcart.co.uk: DIY & Tools

Review: Versatile, quick and easy to check for embedded damp without surface damage. - Very useful tool in checking for hidden excess dampness in buildings and materials without leaving any marks or surface puncture damage. Quick to use with options for either surface testing pins or non damaging deeper embedded moisture and also choice of wood or general building material. Works well with wood, blocks, concrete, plaster ect. Even locates damp areas behind 'foil backed' plasterboard. Have found it can gives a false positive sometimes with some natural building stones, but this can be checked against known dry sample. Readings should be treated as indicative of relative dampness, which it is good at, although as with all these meters a digital reading calibration function would have been useful. Easy to use, clear large display. Good value. Highly recommended.
Review: Really easy to use, does the job, saved us money in finding leak - Used it to successfully locate the source of damp in our kitchen and one of the bathrooms. Thanks to this handy little device we didn't have to tear up the entire rooms to find the problem, which turned out to be a leaky pipe in both cases. We could pinpoint where it was wettest and then just remove that tile, and in fact that's where the problem originated from. We found it very easy to use despite having virtually zero DIY experience, and well worth the investment. Will definitely be using this regularly to check the bathrooms and kitchen in our place.

**Q: Want to use a tester on inside walls of caravan/campers without damaging them. Would anyone recommend this? Thx**
