I picked up an old moisture meter second hand years ago. The probe looks similar to this…

and the meter looks similar to this….

I’m gearing up to make a project with reclaimed lumber that’s been air drying since ‘96 and I’d like to know it’s moisture content.

The only time I’ve seen an old style meter like this used was at a saw mill years ago and I recall the guy looking up some numbers in a table. I think he might have been looking up some kind of correction factor, possibly for wood species or temperature or something.

Any body out there ever use an old style meter like this who can shed some light on the subject?

I don’t think Al Gore invented the interweb yet, when this guppy was spawned

Bubble head you are correct, He was looking at species correction factors. And if I am not mistaken these “correction factors” are all based on the specific conductivity of each species. I wouldn’t be surprised if some of the saw mill owners here on LJ’s had one of these charts laying around.

I did a little research as I’m looking for a new meter for myself. Looking at your pics it looks like yours is an older Delmhorst model. You can go to Delmhorst.com and download the manual for it if that’s who made yours.
I was only half right about the calculations, The correction factor is based on wood density which is different from one species to another.

BTW, even as an older model, that is a very high end model you have.

Thanks for the link Scot,

I was able to identify both my meter and electrode, as well as get instructions and tables for a similar, but newer model.

I’ll have to contact them and see how much new pins cost, as the insulation is chipping off of mine.

Looks like their are correction tables for both temp and species, so I guess my recollection was pretty good.
