Great product; it measures wood from 5 – 50% +/- 3% accuracy We were getting hardwood floors installed – or so we thought – when the installers notified us that they could not do the installation because the wood in our house had acclimated to 6.4% moisture and our subfloors were at 12.8% moisture. The installer found a leak in our water softener line which we got fixed the next day. Unfortunately, we had no way of knowing (ourselves) when to call the installer back. Hence, we purchased this meter.As far as we know, it works great. We aren’t too concerned with the overall accuracy of the instrument, +/- 3% is just fine for us as we’re looking to compare the difference between two materials in our home (assuming the error is consistent between those readings). The resolution of the meter is 0.1%.Other things you might want to know:- It comes with it’s own 9v battery.- It measures wood between 5 – 50% and 1.5 – 33% for other building materials.- It has a hold feature which allows you to save the…

Good Meter with a Long Power-On Delay I bought the General Tools MMD4E Digital Moisture Meter to check the moisture of some flooring and trim moulding for house I am building. At the price of this product, I don’t expect much in the way of absolute accuracy. Instead what I want is relative accuracy. In other words, I don’t care if the wood has 8% or 10% moisture content. What I want to see is, what does the wood do over time. Once the reading stops dropping, the wood has mostly gotten as dry as it is likely to get in its present location. I tested the meter by taking a variety of readings to see if I could reproduce a giving reading. I went from dry wood to wet and back to dry. It seemed to be able to reproduce readings with a reasonable reliability.The meter has a peculiarity that I think is responsible for another reviewer thinking his meter was broken, resulting in a 1-star rating. If the meter has not been turned on for a while, you have to hold down the on/off button for 4-5 seconds to turn the unit on…
