Working on the Measuring Cuvette
Warning hot Surface
During operation, the test gas inlet and outlet are directly connected to the heated cuvette. The surface
temperature of the sample gas inlet and outlet connections may exceed 100°C.
Direct contact with the hot parts for dismantling or maintenance will cause severe burns!
The cuvette may only be removed with heat-insulated gloves. Before removing the cuvette, always switch
off the supply voltage to the electronic system. After removal, store the probe in a safe, protected place
and wait until it has cooled downs below 35 °C (95 °F).
