Question 1

I am trying to find an affordable meter to use on boats.  does this mmd950 moisture meter read through laminates to read core wetness levels?

Accepted Answer

Yes! it is by far the best one on the market, it's ACCURATE !!! I am a fiberglass and gelcoat repair expert, this is the very one I own.... the back flat part reads 3/4 inches deep, but the probe goes in four inches deep! the only "real one out there" technology has changed a lot in thirty years, I've been in the business of gelcoat colormatching as well as the glass work, guess what? it even comes with needle probes to run down wall leaks in sheetrock. This is awesome and the best, by far... better then the over a thousand dollar ones! Get it you'll love this thing and be armed with the best unit money can buy too! Good Luck  they call me "Dr. Gelcoat" New Smyrna beach Fla...

Question 2

I recently had moisture on the floor on one end of my basement. Could this be used to detect if there is also moisture present behind the drywall, within the wall? (The drywall is plastered, painted, and seems to be backed with a layer of plastic.) Thank you!

Accepted Answer

Well! I decided to keep my MMD950 after some calibration problems. It needs to wander and end up stable at 0 to 2% if the calibration is successful. The instrument is reliable when used in a comparison mode. On sheetrock if no water is present it'll read 7 to 9 in the REL mode. If there's water it will jump to at least 17 and maybe even 99%. On roof leaks, I feel it will pick them up, dry days showing a low reading and rainy days jumping significantly. If I were you, I'd take REL reading at various points on the wall around the basement and see if they show dry in some places. Then, over above water pool, check and see if you get a higher reading. The book says the meter shows four inches deep. I have no experience to confirm that. Don't be afraid to open up the sheetrock to look behind it. You gotta know what's going on.

Question 3

will this work on bamboo flooring and concrete sub floors?

Accepted Answer

Should work on the bamboo flooring but not so good on concrete. Concrete always retains moisture so you will always will get a moisture reading no matter what

Question 4

Would this unit read to 0.1% up to 10% or more moisture?  Wish to use it on a food product

Accepted Answer

Your use of the number 0.1% would indicate you're looking for a high level of accuracy. I figure the meter is good for two or three percent plus or minus. I use mine to detect roof leaks. Six to 10 is no leak and 18 or above is a leak. Of course, as stated in the meter description, it'll measure zero to 99%. May be I don't fully understand your question!
