The complete tested modular measuring equipment is composed of the sampling probe, the heated sample gas line, a two-stage sample gas cooler, a gas pump and the multi-component analyzers, ULTRAMAT 23 and SIPROCESS UV600.
An electrochemical or a paramagnetic oxygen measuring cell can be used for the measurement of oxygen.

The gas path splits in parallel after the sample gas cooler. This separately supplies each analyzer with sample gas. One advantage for maintenance is that each analyzer can be individually serviced without affecting the other. The sample gas coolers used have a moisture alarm in case of malfunction. For additional protection, each analyzer is protected by a condensation barrier, which stops the gas flow if moisture penetrates. This guarantees optimum protection for gas analyzers.
For semi-automatic calibration of the zero and calibration gases, a 3/2-way solenoid valve is installed between the first and second cooling stages. The valve can also be used for AUTOCAL calibration of the ULTRAMAT 23 (fully automatic timing) as well as by the integrated PLC (LOGO module).
