Non-Invasive Wood and moisture Meters
Getting away from all the concrete stuff. I am in need of a new non-invasive moisture meter, maybe one that also does wood as well. But I do laminate inspections over concrete as well and need one that can do it all.

Whatcha got?

RE: Non-Invasive Wood and moisture Meters
I have a Tramex CRH. I actually had three of them I used for RH testing, until I found out what a pain they were to keep in calibration and how long they took to measure RH accurately. I gave two away and I'm keeping one for display during lunch-n-learns....

RE: Non-Invasive Wood and moisture Meters
Thats not quite on topic but, I have a non-invasive tramex for wood (wood encounter), works ok but I was a new one with all the bells and whistles, like the species specific gravity and all that. Gets old checking the chart but then, I might not trust a meter to do it.

Got the whole Tramex flooring inspectors kit several years ago, plus another pin meter from lignomat. So I got 2 pin meters to double check wood and then the wood encounter.

I hear Wagner does not believe in pin meters. I'd like a scientific explaination of that if someone could.

RE: Non-Invasive Wood and moisture Meters
What do you mean when you say Wagner doesn't believe in pin meters?

If you are asking if Wagner disputes the results of electrical impedance readings, I would say YES!

EI readings only measure the top surface of the concrete, and they are easily swayed by concrete composition including fibers, steel reinforcement, density, aggregate type, etc. etc.etc.

And again, they really tell you nothing about the concrete.

I'm strictly speaking pin meters for wood, you know like hardwood and soft woods.

Jason said they never have made a pin meter. Which I feel is astounding because every other manufacturer has.

RE: Non-Invasive Wood and moisture Meters
Perhaps Wagner just like to be different. Just look at Rapid RH!. They have their electromagnetic wave system for the MMC220. Non destructive is a bit of a bonus in our industry. Those pins- the flooring looks like its been attacked by snakes. And the MMC's readings do go deep! Yes, I know I sound like an ad for Wagner (Jason PM me for my mailing address when you're ready to send the cheque).

Agreed that I don't trust a meter to adjust for species but hey, you can always calibrate it for Oregon or Douglas Fir or whatever the starting point is, and use a chart to check the meter's accuracy!

But yes, as for what JD said- if you're talking concrete, drill, baby, drill!
