Description
With the testo 635-1 temperature and humidity meter, you can measure temperature, humidity and dew point - even in compressed air. State-of-the-art technology and a large selection of optionally available probes enable this measurement versatility.
The testo 635-1 temperature and humidity measuring instrument is ideally equipped for checking humidity, temperature and dew point in living spaces, 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.
Through connectable probes, which are optionally available, the measuring instrument records the following values:
- Humidity
- Material humidity
- Pressure dew point in compressed air
- Air temperature
- Surface temperature
- Core temperature
- Absolute pressure
The testo 635-1 temperature and humidity meter has two probe inputs for plug-in probes with cable. In addition, the testo 635-1 can receive measured values from up to three additional temperature or humidity probes via wireless data transmission and show them on the clear display. To transmit measurement data by radio, you need the optional radio module in addition to radio sensors. It is simply plugged into the testo 635-1 and can be retrofitted at any time. The radio signal between the radio sensor and the measuring instrument carries over a distance of up to 20 meters.
In addition, the measuring instrument calculates the dew point distance 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 was caused by incorrect ventilation behavior or by moisture penetrating from outside.
Product advantages:- with optional available probes you can measure humidity, temperature, absolute pressure and dew point in compressed air
- two plug-in probes and 3 wireless probes can be connected
- calculates dew point and dew point distance
- display of min-/max- and average values
