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
