Moisture Meter Testo 605-H1

It has a permanently mounted sensor probe with flexible probe tube (125 mm) which makes it excellent for control measurements in boreholes and ventilation ducts. The instrument measures relative humidity 5–95%RH and temperature 0…+50 °C, and calculates dew point in the range -20 to +50 °C. The built-in testo sensor provides reliable measurement results with high long-term stability. The display can be angled for easy reading and the rotatable protective cap protects the sensor during storage.
