A: The MMH800 is designed for use in woodworking, water damage restoration, building construction and home renovation.

    I already have a damp meter that uses two prods that need to be pressed on the walls. We have a wall that registers damp, and as such, the prods tend to make imprints in the relatively soft plaster, and after repeated tests, the wall becomes unsightly.This General Tools Moisture Meter works in a different way. There is a pad on the back of the device that just needs to be placed on the surface in question to obtain a reading. There is an immediate colour-coded response, and the definite benefit of this meter for me is that it can be moved across a wall, obtaining continuous readings, therefore easily identifying the limits of a damp area. The other meter I have needs to probe the wall, then be moved elsewhere multiple times, leaving the wall like a pincushion.The instructions for the meter confirm that the readings are not absolute, but their relative nature means that differences in moisture can be readily identified. Certainly the readings are very different from those on my second meter: where this one gives a 100% reading, the other is giving around 20%. So there's no need to panic at a 100% high reading. However, using this meter I have been able to establish it is a chimney flue simply by the dogleg route I have been able to locate.Recommended.It is an excellent meter; not definitive but certainly indicative enough to enable me to proceed with sorting out the problem.
