Product Overview

The TESTO 605-H1 is a compact thermohygrometer. 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. It has a permanently mounted probe shaft which means it is excellent when it comes to carrying out check measurements in ventilation ducts. The TESTO 605-H1 is ideally suited for duct measurements due to its slim form factor and ability to be read from multiple angles with a rotatable probe. 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.
