Description

The temperature and humidity measuring Instrument testo 635-1 is perfect for checking air humidity, temperature, and dew point in living rooms, production, storage, and server facilities, as well as museums and cold shops. It also allows for quick and accurate readings of ambient absolute pressure and dew point in compressed air.

Optional probes are attachable and can be used to record the following values:
• Air humidity

• Material moisture

• Compressed air pressure dew point

• Air temperature

• Surface temperature

• Core temperature

• U-value

Two probe inputs for plug-in probes with cables are available on the testo 635-1 for temperature and humidity measurement. Additionally, the testo 635-1 may show up to three additional temperature or humidity probes via radio-controlled data transmission, i.e. wireless.

Robust, practical and easy to handle
In addition to measurements, the testo 635-1 temperature and humidity measurement equipment provides min., max., and mean values.
The dew point and water content of interior air, as well as the psychrometric temperature and air humidity and temperature, are measured by the pressure dew point probe, whereas the humidity probe measures the dew point and water content of interior air, as well as the psychrometric temperature and air humidity and temperature.
The measurement tool also calculates the dew point distance between indoor air and wall surface. The “Applications” tab in testo 635-1 shows if a mould infestation in the home was caused by poor ventilation or moisture infiltration.
The user-friendly menu navigation, lighting feature for reading legibility even in low light, and impact resistance thanks to its sturdy housing differentiate the Testo 635-1.

Documentation of measurement data with testo 635-1 temperature and humidity measuring instrument
You can print measurement data such as air humidity or temperature at any time with the testo fast printer, which is offered as an option.
The testo 635-1’s practical cycle printing function allows you to print full series of measurements at freely configurable intervals on the testo fast printer, in addition to individual readings (for example once a minute).
