Hygrometer testing

box showing 70% when heating is off

 

So is a wolff GM 200 going to give reliable information on a concrete over wet UFH subfloor?

 

It doesn’t pick up the pipes if that’s what you mean?

Thanks, that was surprisingly fast

 

Looks like my old fish finder

 

Late to this, but how will RH go up when ufh is running? Surely amount of moisture in slab is fixed at any given time so an increase in temperature will reduce the RH?
