6.2.6. testo 6617 cable probe (self-monitoring)
The testo 6617 probe is used if spatial separation of the transmitter
and probe is required, particularly for media (gases, vapours) which
can jeopardize/damage the humidity sensor (the testo 6617 has a
self-monitoring and early-warning function for such applications).

WARNING
In the event of overpressures, the probe may become a
projectile.
> Mount the probe pressure-tight (see pressure resistance under
Technical data)
Application
• Monitoring and regulating industrial humidity processes
involving corrosive media (apart from high-humidity processes)
with the exception of applications with HCL, HF and other acids
and acidifiers in larger concentrations (SO
2
, SO
3
, NO
2
)
• Meeting the top accuracy requirements
• Applications for which a sturdy metal housing is required
This probe does NOT have a longer life with exposure to
aggressive media than the testo 6613, for example.
However, early warning of damage to the sensor is given
so that machine failures can be avoided.
