Connection of 2 plug-in probes and 3 wireless probes Measurement of temperature, air humidity, material equilibrium moisture, pressure dewpoint, absolute pressure and U-value Display of dewpoint distance, min., max. and mean values Illuminated display Protection class IP 54 Instrument store for 10000 measurement values (testo 635-2 only) PC software for archiving and documenting measurement data (testo 635-2) Humidity/temperature measuring instrument testo 635 – Measurement technology for humidity measurement %RH hPa The testo 635 offers the possibility of testing and analyzing air humidity, material moisture, U-value and the dewpoint in compressed air systems. In addition to measurement with classical probes, a wireless measurement over up to 20 m distance is also possible with the testo 635. This eliminates damage to the cable or difficulties in handling.The wireless probes are available for the measurement parameters temperature and humidity, up to three wireless probes can be recorded and displayed by the testo 635. The optional plug-in radio module can be retrofitted at any time. The testo 635 stands out thanks to its intuitive operation and clear menu structure. For example, for measurements at different measurement sites, the testo 635-2 provides the advantage that the measurement values can be allocated to the respective measurement site. For long-term measurements and material moisture measurements, the instrument can be switched between different user profiles. The testo 635 is available in two versions. The version testo 635-2 has extended instument functions such as an instrument store, PC software, direct display of material humidity and the possibility of connecting a U-value probe www.testo.com We measure it. testo-635-P01 06.08.2013 14:18 Seite 1
