The testo 605-H1 Mini Thermohygrometer is designed for accurate and convenient measurement of humidity, air temperature, and dew point in a variety of environments, including ventilation ducts, storage facilities, production areas, and offices.

It measures air temperature from 0 to 50˚C with an accuracy of ±0.5˚C and resolution of 0.1˚C, as well as relative humidity from 5% to 95% RH with an accuracy of ±3% RH and 0.1% resolution. The instrument also automatically calculates dew point in the range of -20˚C to 50˚C, helping to prevent condensation-related issues in HVAC systems.

One of the standout features of the testo 605-H1 is its permanently mounted probe shaft (125 mm), which is particularly useful for hands-free measurements in ventilation ducts. The included bracket allows secure positioning, eliminating the need to hold the instrument during readings.

The pivoting display ensures easy visibility from different angles, even in tight spaces. Additionally, the flexible probe joint allows for precise positioning, making it easier to obtain accurate readings in complex ventilation systems.

With a 1000-hour battery life, the testo 605-H1 is built for extended usage without frequent recharging. The rotating protective cap helps shield the sensor from mechanical damage, ensuring long-term reliability.

This mini thermohygrometer is a must-have tool for professionals working in HVAC, facility management, and environmental monitoring. It provides a compact, easy-to-use, and highly accurate solution for measuring air temperature and humidity with confidence.
