b) Measuring Procedure

Temperature Measurem.: K-type thermocouple (

) for waste or flue gas temperature

for air or ambient temperature.

O2-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.
