Worked well in caravan

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.

Nothing to dislike, damage free inspection of plaster board etc with the benefit of pins for checking masonry and timber etc

I do not feel sure that this gives accurate readings.

Great piece of kit, does what is advertised and easy to use.

Great damp meter at Amazing price

Did the job

Exactly what I wanted.

Bought this tester to check on damp in caravan. Very easy to use with the pins that give a reading without requiring piercing materials. The added benefit of the flat surface scan gives depth readings which is very useful. A backlit display would be a bonus.

Advantages: Pin and pinless mode in one instrument. The pinless mode allows quick scanning of walls. The device seems to give the correct general behaviour i.e. damper materials give higher readings and (usefully) faster beeping when sound is on. So far, the readings seem reasonably reproducible - going over the same area again give more or less similar readings. It isn't expensive.Drawbacks: Absolute readings in pinless mode do not seem credible (it overestimates - bone dry plaster on block reads about 19%). The pinless comparison mode (whereby you can zero the device on a known dry material before testing damp specimens) does not work - the device does not zero when switched on in contact with the dry reference.
