b) Measuring Procedure
Temperature Measurem.: K-type thermocouple ( ) for waste or flue gas temperature
for air or ambient temperature.
O -Measurement : Electrochemical measuring cell.
CO-Measurement : Electrochemical measuring cell.
Draft Measurement : Piezo-resistive principle with internal temperature compensation.
Measuring Duration: Short-term memory measurements of max. 60 minutes are possible, followed by
a new calibration phase with ambient air.
Waste Gas Measurement : Via an external water separator and filter, the waste gas is fed to the sensors by
means of a gas feed pump. The pump capacity during the feeding phase is
approx. 0.8 l/min.
Sensor Calibration: 60 seconds after switching on the instrument.
CO Concentration: CO sensor with H compensation, measuring range 0 - 4.000 ppm. Cutoff
threshold at 4.000 ppm for sensor protection via separate flush pump.
The remaining measuring values are not affected. The instrument is switched on
again at a value of 1.600 ppm.
Waste Gas Sampling: By means of a waste gas sampling probe with retainer cone.
