Pressure/draft Piezo-resistive sensor with internal tem-
perature compensation
Measuring duration Short-term, stable measurements of max.
60 minutes are possible, followed by a
new calibration phase with ambient air.
Flue gas measurement Via an external water separator and filter,
the flue gas is supplied to the sensors by
means of a gas pump.
Sensor calibration After switching on the instrument, there is
a calibration phase that takes 30 seconds
after a cold start.
CO Sensor protection The standard CO sensor with dynamic H2
compensation is protected automatically
by separate flushing pump. When the
permissible concentration of CO is
reached (>4000 ppm), the additional CO
pump turns on and flushes the sensor
with fresh air. The measurement starts
again automatically when the CO concen-
tration drop below 1600 ppm.
Flue gas sampling Flue gas sampling is done by means of a
probe which en
ables either a “one-point
measurement” (combi probe) or a “multi-
point measure
ment” (multi-hole probe).
WARNING 
The life of the sensors depends essentially on utilization and
use of the instrument. The expected life of the gas sensors is
about 24 months.
