Relative Humidity (RH) Moisture Meters for Concrete

Set concrete cannot be easily penetrated by a pin meter, and it wouldn't allow for measuring in the core of the slab anyway. Therefore it’s often best to measure concrete with an thermo-hygrometer (RH meter). These devices comply with the global measurement ‘gold’ standard known as ASTM F-2170-11.
