Review: Works well - Works fine for me!
Review: A very good non-invasive meter - 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.

## Questions & Answers

**Q: Does it sense moisture through a painted surface or just the moisture content of the paint?**
A: It senses moisture through a painted surface.

**Q: Can this be used on concrete and drywall?**
A: Yes, the device has four modes.  Wall, masonry, soft wood, hard wood.  Wall is drywall.

**Q: Can this be used to locate a leak behind drywall. The drywall is not showing wetness so the water is probably running down a stud or outside wall.**
A: This tool will measure the moisture content of any building material including wood and drywall. If the test indicates a high moisture content in just one spot, you could probably conclude that there was a leak at that point.

**Q: Will this unit work on a plywood sub floor, and hardwood flooring to verify the hardwood has properly aclimated for installation?**
A: In order to get accurate readings you will need to make sure the two prongs on the top make contact with the area you wish to measure for moisture.  The two prongs are pretty small and the tips are sharp.  I was able to obtain readings on wet drywall, plywood and ceramic floor tile. As long as contact was made with the points it worked for me and the price is reasonable.
