Weird moisture meter readings

So im inspecting this home and I just got a moisture meter. I go around text some areas below the windows then just for shots and grins I test random areas. I put my meter on the corner if a wall and it goes crazy. Like 60%, go to another corner sane thing. Begin to suspect that my meter isn’t telling the truth so when I get home I test my walls corners and same thing. Am I missing something about these meters? If it matters I’m using pinless.

What brand and model meter?

They react to metal (corner beads, nail protection plates, some ceramic tiles, etc…), check the manual.


Exactly, Simon.


Aaahh thank you!
