Amateur meter not for professional use
Amateur meter not for professional use, I used this next to a MMS2 and it offered differing readings, this machine is OK for occasional domestic use but not for a professional.

Worked as described appears to be a great product.
I was having a problem with moisture in a couple of basement apartments so I wanted to determine the source of the moisture. This tool appears to work very well for this application.

Reasonably Reliable Tool
I'm a general contractor and I find myself occasionally having to test for moisture in a client's home. This is my second General Tool moisture meter. This model - the MMH800 - has more functions then my previous one including the ability to test for moisture as well as providing a temperature readout. The meter is a dual-function pin and pin-less model which allows testing without leaving holes in walls or woodwork. I had the opportunity to be on a customer site with a mold remediation tech who was taking moisture readings to determine possible wet areas that might have been contributing to a mold issue. The tech didn't tell me the model he was using other than it was a professional -series, scan-only type and that it was very accurate with a good scan depth. When I compared my readings from the MMH800 with the tech's meter I found very little differences in the readings. There is one inherent limiting factor with all pin meters and that is they only test to the depth of the pins, useful on drywall or wood but very limited on masonry and/or concrete. Concrete testing is virtually unreliable due to the penetration issue. The ability to take a scan reading alleviates some of that issue. What I like most about the MMH800 is that is reasonably accurate and affordable. Adding a moisture meter (along with a good gas sniffer) to my tool bag provides data which ultimately allows me to better serve my customers.
