Description
Measuring device for measuring air humidity, material compensation humidity and for measuring the pressure dew point in compressed air systems.
Humidity curves can be recorded and analyzed and displayed graphically/in tabular form. Wireless, i.e. with data transmission by radio, up to 3 temperature or humidity sensors can be displayed in the Testo 635-2 measuring instrument. User profiles can be selected, i.e. the assignment of the function keys and menu navigation adapted to the application enable intuitive operation.
The material humidity can be displayed directly due to the special sensors. Characteristics for different materials can be stored in the ComSoft and transferred to the measuring instrument. For analysing the humidity at roofs and walls the testo 635 shows directly the dew point distance between the room air and the wall surface. For testing the pressure dew point in compressed air systems precision sensors up to -60°C tpd are available.
The humidity sensor developed by Testo itself is proven worldwide and offers outstanding properties in terms of precision, long-term stability, temperature resistance and robustness.
