testo 635-2 humidity/temperature measuring instrument
with memory, PC software, and USB cable for data transfer, including battery and calibration protocol

The instrument is designed for measuring air humidity, material equilibrium moisture, and pressure dew point in compressed air systems. Humidity characteristics can be stored in the device’s memory, analyzed, and then displayed in graphical or tabular form. The device’s display can show data from up to three radio probes for humidity or temperature, transmitted wirelessly via the radio option (*please check the availability of this option in your country).

Selectable user profiles – for example, assigning specific function keys to particular tasks – and a user-friendly menu make the instrument intuitive to operate. Material humidity can be displayed instantly when a special probe is connected.
Characteristics for different materials can be pre-set in the ComSoft software and transferred to the instrument.

When analyzing wall and ceiling humidity, the instrument immediately displays the dew point difference between air temperature and wall surface temperature.
For measuring the pressure dew point in compressed air systems, high-precision probes are available (up to -60 °Ctd).
The Testo humidity sensor is recognized worldwide for its outstanding accuracy, long-term stability, temperature resistance, and robustness.

Internal memory for 10,000 measurement datasets

PC software for analysis, archiving, and documentation of measurement data

Measurement of air humidity, material equilibrium humidity, and pressure dew point in compressed air systems

Wireless radio probes for temperature and humidity

Protection class IP54

testo 635-1, humidity and temperature measuring instrument
Includes battery and calibration protocol

This instrument measures air humidity, equilibrium moisture of materials, and dew point under pressure in compressed air systems. The display can show data from three humidity or temperature probes; data transmission can be done wirelessly using the radio option 9* (please check if this option is available in your country). Measurement data can also be sent to a Testo printer via the infrared port. During cyclic printing, data can be printed at regular intervals, e.g., once per minute. The instrument instantly shows the dew point difference between air temperature and the surface temperature of walls when analyzing wall and ceiling moisture. Precise probes are used for measuring dew point under pressure in compressed air systems, down to -60 °C. The Testo humidity sensor is globally recognized for outstanding accuracy, long-term stability, temperature resistance, and durability.
