Hello all,
Looking for a moisture meter for engineered wood flooring installations on both plywood & concrete subfloors. I'd like a meter that won't break my wallet but rather gives me the most bang for my buck.
Suggestions?
Thanks!

Harbor Freight has one for wood that costs less than $20.

Hmmm, well IMO if you install professionally you should have a professional grade meter. Take a look at the Lignomat SDM and the higher grade one that does insitu testing. Only a couple hundred bucks. It is the only one on the market that can read at 1/4 inch and 3/4 inch depth so your not reading anything below when checking installed floors.

Thanks!
That's quite a difference from $20-$200. FWIW, I don't install professionally; I am renovating my home so, who knows how often or when I'll use it again after this.

Looking at HF Digital Mini Moisture Meter item #67143 for $14.99...It has 23 reviews with 4 out of 5 stars (grain of salt taken). Reading through the reviews, I don't recall anyone using it for hardwood flooring but rather more for fire wood and logs.

With that said, this may be a dumb question but...Is wood...wood? I mean...Whether I'm checking the moisture of logs, fire wood, engineered wood flooring or plywood; how well do moisture meters work on different types of wood?

I wouldn't trust a 20 dollar one.

$30 for one with two pins at the top at Home Depot, or $40 for the contactless one, i used the pins one and worked fine for me:)

The expensive ones have a way to read without making holes in the wood surface.
If you want to read deeper with a pin type, you can drive two nails in at the width of the pins and touch the pins to the nails. Kiln dried wood will read pretty much the same on the surface as deeper into the wood. Air dried or green lumber will be wetter under the surface.
The ones for slabs/cement cost plenty and you will have to drill holes to get a depth reading.

Thanks!
What type of flooring and sub-floor did you use it on?

Its best to use insulated pins like I have with my tramex pin meter, it has a hammer probe with insulated heavy duty pins you attach for going deeper. Otherwise your getting an average as the nails are touching all the wood, not deep down below.

I just ordered a Wagner MMC220. I'll post my experience with it after I use it.

Ouch, both of those units are around $300-$400 each. That's a big pop for one-time use.
Does either unit work on concrete?
How deep into the flooring do the pins need to go?
How do you confirmed accuracy of ANY of these unit?

All meters will give you a slightly different reading.

On a solid go as deep as possible.

On engineered when you go through different layers you may get different readings. Then if one pin is in the bond layer you will get a bad reading. Thats why non-invasive meters read better on engineered.

Also annual calibration of a meter is a necessity. Many new ones you can calibrate with a tool they send you. Some you have to send in.

Very helpful, thanks!
