The testo 635-2 temperature and humidity meter is ideal for carrying out various measurement tasks in the air conditioning sector. Testo also offers you a wide range of compatible measuring heads (optional) for these measurement tasks, such as:
- Relative humidity
- Material moisture
- Material compensation moisture
- Dew point pressure in compressed air systems
- HTC value
- Air temperature
- Surface temperature
- Core temperature
- Absolute pressure
Provide cover: testo 635-2 thermo-hygrometer, PC software, USB cable, batteries and test certificate. PLEASE NOTE: to be able to operate the testo 635-2 you need at least one compatible measuring head from Testo (optional).
Outstanding features of the testo 635-2 temperature and humidity meter
The testo 635-2 temperature and humidity meter can display Max./ Min. and average values. At the same time, the testo 635-2 calculates the dew point difference between the indoor air and the wall surface. This enables you to analyse the humidity levels on ceilings and walls. Individually programmed characteristic curves ensure that the material humidity is displayed accurately and reliably.
In particular, the features and interface on the testo 635-2 are very intuitive and extremely user-friendly. The integrated display light allows you to read the measured values in low light conditions. The sturdy protective case helps protect the device from unwanted impacts.
The testo 635-2 also enables you to allocate measurement data to relevant measuring locations. Create individual user profiles in case you need to carry out multiple material moisture measurements simultaneously over a long period of time.
The included USB cable can be used to connect the testo 635-2 to a PC and software allows you to record and store measurement data comfortably and easily.
In addition, you can export measurement data to paper on site using the fast printer provided by Testo (optional order).
