Hand-operated waste gas analyzer for determination of heating installation performance

摘要

A hand-operated waste gas analyzer has a probe tube (8) containing a thermocouple and fixed to the housing (1) of battery-powered processing electronic equipment and pressure, oxygen and carbon monoxide sensor cells. A hand-operated waste gas analyzer comprises a rigid probe tube (8) which contains a thermocouple measurement cell and which supplies a gas sample to a pressure sensor, an oxygen sensor and a CO indicator. The tube is fixed to the housing (1) of battery-powered processing and measuring equipment. A pump draws a gas sample continuously through the probe tube (8) and over the cells and the measurement values of the cells are alternately and/or simultaneously processed, displayed (16) and optionally stored. An Independent claim is also included for a sensor arrangement especially for the above analyzer, the probe tube end being fitted with a condenser (11) which subjects the gas sample stream firstly to flow reversal and turbulent components, secondly to a flow component in the main flow direction and thirdly to a flow reversal component.
