Customer Reviews

Rated 4.1 out of 5 by 7 reviewers.
Rated 5.0 out of 5.0 by Very easy to use This meter is very simple to use. Switch on, push onto the material, and read the moisture content! Could not be easier. There is also an audio signal for low/medium/high moisture ranges and the ability to lock a reading for hard to reach areas. I obtained readings from 5% to 19% around the house and some seasoned firewood I bought. The current humidity and temperature is also displayed. There are two modes of measuring, using the sharp pins or a pair of flat sensors on the back which are to be pressed onto the material being measured. One can measure the humidity of either wood or masonry materials. There is a good protective cap to keep the sharp probes from getting damaged and injuring the user. The case it comes in is mostly marketing. It is made to look like some expensive instrument case but in reality the inside is just a cheap plastic insert and the box is mostly empty. It would make a nice lunch box! September 4, 2014
Rated 5.0 out of 5.0 by great little gadget I used the moisture meter on it and it was simple to use ,compact, and very user friendly July 22, 2015
Rated 5.0 out of 5.0 by Helpful Evaluation Tool This is the most useful tool to evaluate any home. I used it to ensure that our bathroom which previous had a leak, is no longer leaking. You can either use the needles on the top to poke into wood, or slide the meter along the floor for a reading. When I was testing the basement it was hard to see the screen and the meter chirps warnings when the moisture level is medium or high, which is helpful. You can also lock the screen after a reading and then look at the number later. Overall I highly recommend this, it can save you lots of money by proactively looking for water related problems.

Rated 5.0 out of 5.0 by This tool saved me thousands of $ I was doing a home inspection on a house i put a contract on and and my inspector buddy let me borrow this because he said i couldnt do an accurate inspection with out it. I was amazed when i started scanning the stucco and some areas in the basement and found high moisture levels. Upon further inspection i could check temperature on the windows showing that the windows were poorly insulated. This tool was the perfect tool for the job so that is why iam writing this review and will purchase with the money i saved from not buying the house that would have been a money pit.

Rated 5.0 out of 5.0 by Definitely would buy again!!! This is an excellent product and value for the money!!! April 27, 2015
Rated 3.0 out of 5.0 by Does what it says This meter is pin reading or surface reading if you want to read the moisture behind a wall or inside the wall you need the MM990 meter instead. I returned this and bought the 990 it works much like the Proscan GE meter and so far in comparisons it seems to be very accurate for one fifth the cost of the Protimeter surveymaster we'll see how it holds up.

Rated 1.0 out of 5.0 by Useless Read 0% on various lumber, both kiln dried and air dried. Read 4 to 6% on fresh logs stored outside. it is impossible for the readings to be correct. This meter was worthless to me and has been returned. February 17, 2015
