Just wondering if anyone in the home building / repair industry has any experience with using moisture meters? There are different types, intrusive (2 pins that you dig into your material like dry wall) or non-instructive (some kind of flat sensor that you press against the face of your material).
I've had a look at some sensors out there that are available and I am trying to figure out if the soil moisture sensors would do the same job if they were pressed against a sheet of damp dry wall?
I've heard that the intrusive meters with the pins work kind of like the way a multi meter works for measuring resistance?
Still trying to figure out where I need to start my research so any pointers would be greatly appreciated.
