The Testo 605-H1 thermo hygrometer provides fast and accurate humidity, temperature drybulb and dewpoint readings. Small and compact, it is suited for taking air humidity measurements in ducts. The Testo 605 H1 is particularly versatile and convenient to use thanks to its joint. The display can be rotated into different positions, allowing optimum read-out of the measurement values. The long-term stable sensor guarantees correct measurement results even after years. The probe shaft has a length of 125 mm and can be ideally positioned in the duct using the holder included in delivery. The rotatable protective cap protects the sensor from dirt and impact.
