testo 635-1 temperature and humidity measuring instrument
The testo 635-1 temperature and humidity measuring instrument is ideally equipped for checking humidity, temperature and dew point in living rooms, production, storage and server rooms as well as in museums and cold stores. Measurements of absolute pressure in the environment and dew point in compressed air can be carried out quickly and efficiently with the testo 635-1.
Using connectable probes, which are optionally available, the measuring instrument records the following values:
- Humidity
- Material moisture
- Pressure dew point in compressed air
- air temperature
- Surface temperature
- Core temperature
- U-value
- Absolute pressure
The testo 635-1 temperature and humidity measuring instrument has two probe inputs for plug-in probes with cable. In addition, the testo 635-1 can receive the measurement values from up to three other temperature or humidity probes via wireless measurement data transmission and show them on the clear display.
In addition to wireless probes, you need the optional wireless module for wireless measurement data transmission. It is simply plugged into the testo 635-1 and can be retrofitted at any time. The radio signal between the radio probe and the measuring instrument carries over a distance of up to 20 meters.
Robust, practical, easy to use
In addition to the measured values, the testo 635-1 temperature and humidity measuring instrument also displays minimum, maximum and average values.
If a pressure dew point probe is connected, it measures the pressure dew point in compressed air. If a humidity probe is connected to the measuring instrument, it measures the dew point and water content of the room air as well as the psychrometric temperature in addition to humidity and air temperature.
The measuring device also calculates the dew point difference between the room air and the wall surface. In the event of mold in the home, this gives you an initial indication of whether mold has been caused by incorrect ventilation or by moisture penetrating from outside. In the "Applications" tab, you can find out more about measuring mold in the home with the testo 635-1.
The temperature and humidity measuring instrument is extremely easy to operate and the menu navigation is convenient. Thanks to the illuminated display, you can easily read the measurement values even in poor visibility conditions. A sturdy housing reliably protects the measuring device against impacts.
Documentation of measurement data with the testo 635-1 temperature and humidity measuring instrument
Would you like to document your measurement values quickly and verifiably? With the optional testo quick printer, you can easily print out measurement data such as humidity or temperature at any time.
Use the practical cyclic printing function on the testo 635-1, which allows you to print out not only individual values, but also entire measurement series on the testo quick printer at freely adjustable intervals (for example, once a minute).
