Testo Moisture Meter

The Testo 605-H1 thermal hygrometer is capable of precise measurements of air humidity and air temperature, as well as calculations of dew point temperature. With its long term, resilient, Testo patented sensor, the 605-H1 thermal hygrometer can provide correct air humidity, air temperature, as well as dew point calculations for in-duct, as well as ambient conditions.  The rotating cap will further protect the sensor from dirt and impact, ensuring reliable measurements for years.
