Moisture meter recommandations
It looks like this might be my next tool investment. How much do you need to spend to get a decent one of these? Any recommendations? Primarily for drywall and wood.

They start out at $30 to around $400.

I have a competing model but the Lignomat mini-Ligno S/DC gets good press

Issue 5 of the free On-line Magazine This Is Carpentry has an excellent overall view of Moisture meters starting on p76

Moisture Meters
I was browsing the web and ran across this thread. I'm the owner of (just to be clear, I'm not trying to spam this forum).

I'm assuming you're working with the wood and drywall before they're installed. Afterwards, it gets a bit trickier.

I'd recommend you go with a Wagner, probably an MMC 220. That's you're best bet for accurate readings.

For important background info, whatever brand of meter you get, take a look at this Moisture Meter Video Library that Wagner put up on their website. This side of things needs to be a science, not an art. Most people know pretty well how to guess at proper moisture content in wood, but for quality work, spend some more time learning.

Oh, and take a look at our Moisture Meter Technology page at, talking about the technology behind pin and pinless meters.

The mini ligno mentioned above may be sufficient for estimates, but it's too sensitive to non-moisture factors. If you're got the money to spend over 100 dollars, just go all the way and buy that 220.

I'd definitely go with the Wagner MMC 220 instead of those listed on that nextag page. The Extech there doesn't deserved to be called a moisture meter any more than two nails, a multimeter, and a correction table does. Perhaps good for a guess, but accurracy is obviously compromised.

If you pay more, do you get increased
battery life
stays in calibration longer
batteries easier to obtain or less costly
less sensitivity to confounding variables

Lots of good info here, thanks. I am going to be renovating my other bathroom and kitchen in the near future. For those I am going to want to evaluate the moisture in the preexisting wall materials to determine the need to either dry out or replace before painting. Further down the road, maybe wood flooring materials. More research is probably a good thing but for my occasional use, I probably don't need to go top of the line.
