To prevent cooling below dew point at the dilution point, the dilution unit  with critical orifice is in-
stalled temperature-stable in the heated part of the gas sample probe directly in the clean gas outlet.
A gas pre-heater  heats the dilution gas to probe temperature. With the option ..B/..BR wit bypass in-
jector the bypass gas is pre-heated as well (double pre-heater). The probe is available with heating to
maximum 180°C or 320°C.
Test gas can be supplied to the probe for analyser calibration via the integrated test gas feed connec-
tion .
