What would I use this moisture meter for?
This moisture meter is for measuring the moisture retention of certain materials to check for damp. It does this by measuring the percentage of water in the material being tested. The moisture meter can be used on wood, breezeblock, brickwork, plaster and more.

How easy is this meter to use?
The moisture meter is easy to use. It automatically turns on when the prongs detect themselves being pushed into a surface. This then triggers the measurement being taken, which is displayed on-screen as a bar.

Rated 5 out of 5 by from Living in a flat and getting regular floods from apartments above, it can be difficult to know when it's good tor proceed with repairs, this helps you know when it's dry. Another bonus is when a leak has been fixed you should start to see it dry (moisture level drop) if not the leak has not been fixed and may be just weeping! Cheap and simple! Batteries may be a pain to replace if an odd size keep this in mind if you work on a building site.

Rated 4 out of 5 by from Does the job I bought this to try to diagnose a slight "damp plaster" smell I was picking up in a downstairs room in our house. Using the meter I was able to check the relative moisture levels of various parts of the walls and ceiling - so it's done what I needed it to do. In reference to phillalf's comment about the instructions, I think he's probably over-complicating things(!). The meter is very simple to use - no settings to adjust, switches to flick, etc. It simply has two scales on the display - one if using on wood or wood derivatives (card, etc.), one if using on other, harder building materials (brick, plaster, etc.). You take the cap off the meter (which turns it on), stick the probes into/onto the material you want to measure and read off the appropriate scale. If it's wood, use the left scale (with a picture of a tree at the top). If it's other building material use the right scale (with a picture of a house at the top). Simple.

Rated 5 out of 5 by from Very good product if you require simple accurate readings Bought to analyse rising damp. Easily measured areas of extreme damp showing over 2% moisture in brickwork and accurately measured everything in between from 0% to 2% easily for me to outline problem. No bells and whistles and professionals may want more however it was great for my simple needs.

Rated 2 out of 5 by from It appear to measure something but what? Neat looking but with the worlds most useless instructions! They tell you can measure moisture and they give its performance. But they don't tell what the two scales on the device are! Or how to switch between measuring moisture in wood or in brick.

Rated 2 out of 5 by from Moisture Readings I usually use a Hygrometer which gives you a % reading of 50-100%. For Anhydrite screeds i usually look for 75-85%. With this moisture reader i cannot calculate a correct moisture %. It could do with a recommended moisture chart?
