Review: I apologize to readers in advance for the lengthy post but I feel like providing the background on which I formed my opinion will be more helpful to you than just my opinion alone. I have used the MMD950 before, many times, while doing home inspections with another inspector. It was his device and I always found myself needing to grab it out of his bag in order to verify the findings of my own moisture meter. I finally decided it was time to get my own BUT then I saw that Flir manufactures a similar model for roughly the same price (the MR59 Ball Probe Moisture Meter $199.00). I ordered the Flir thinking it HAD to be superior... I mean it's made by Flir right?!?! Wrong... and I could not have been more disappointed. Both meters have a great quality and durable feel but in the field, the Flir MR59 produced inconsistent and unreliable results that I just couldn't make sense of. Here's the difference: The General Tools MMD950 takes two types of readings with the ball probe sensor, WME% (wood moisture equivalent) and REL% (Relative Moisture, which is based on the calibrated baseline established when the device is turned on). The ability to take these two types of measurements on the same surface (as well as the pin probes if you're really not sure) allows me to make a thorough and confident assessment for my clients during their inspection. I always knew this was a good meter but it wasn't until I put it side by side with the Flir, that I realized how good it actually is. The Flir comes with some cool features but like I said, I found the readings to be arbitrary and unreliable, for example: Putting the ball probe up to a plaster wall that I was 100% certain was dry, might produce a reading of 37, ok fine. Not 37% moisture, just 37. Now my understanding is that this is what Flir calls a "relative" reading. First of all relative to what? And when I put the probe up to a plaster wall that I am 100% certain has moisture behind it, I might get a reading 63. Ok great, now I know one wall is more wet than the other (which I already knew before I spent $200) but how am I supposed to come to any sort of diagnostic conclusion based on the information the device provides?? If 37 represents a material that is dry, then how wet is a reading of 63??? Other dry surfaces may produce a reading of 0, which is fine considering some building materials naturally have lower/higher moisture content than others. But since Flir doesn't provide any sort of info or chart to indicate high/low readings from one material to the next, the thing really just leaves you guessing. Anyway... I'm obviously frustrated/ disappointed with Flir but felt I should air all that out to really highlight why one should choose the General Tools MMD950. Thank you for your patience if you've made it this far lol. All that to say, I love the MMD950 and would recommend it over any other multi-material moisture meter in this price range. Don't be sketched out by the ball probe if you've never seen/ used one before, it works beautifully and you can opt (like I did) to purchase the more traditional, pin probe extension which plugs into the ball probe unit. Hope this was helpful!

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... **Q: 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!** A: 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. **Q: will this work on bamboo flooring and concrete sub floors?** A: 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 **Q: Would this unit read to 0.1% up to 10% or more moisture? Wish to use it on a food product** A: 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! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***. on 21 August 2020* I apologize to readers in advance for the lengthy post but I feel like providing the background on which I formed my opinion will be more helpful to you than just my opinion alone.
