A test system for gas sensors - ScienceDirect

1995-02-01· Test chambers Test chambers for gas sensors are a vital point of every test system. In order to get reproducible gas mixing at the sensor surfaces, the sensor chambers should be optimally designed concerning the gas flow. The IFT test system provides two interchangeable test chambers, one with a linear configuration (Fig. 6) and the other with a circular design (Fig. 7). Both are optimized ...
