The Protimeter HygroMaster 2 thermo-hygrometer is used to measure relative humidity, air temperature, and surface temperature of structures. Additionally, the difference between dew point and surface temperature can also be displayed for condensation risk assessment applications.

At the time of purchase, choose between the the short QuikStick for general measurement or the HygroStick sensor that is recommended for high RH harsh environment applications such as ERH concrete floor measurement. Both are also available as accessories to purchase in addition or later as replacements. The surface temperature sensor is also available as an accessory.
