The Protimeter HygroMaster L thermo-hygrometer measures relative humidity, air temperature, dew point, and specific humidity (GPP, g/Kg). At purchase, choose between the QuikStick for fast-responding full-range measurement or the HygroStick sensor for harsh and high-moisture applications such as concrete floors. Both are also available as accessories or replacements.
