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 ...

measurement. Indeed, the amplitude, as well as the response and recovery times are very dependent on the testing chamber. In this study, we show that by optimizing the design and reducing the volume of the testing chamber, the responses of metal oxide microsensors are highly enhanced and faster, and therefore closer to the real behavior of the sensor.

SR-3 Bench Top Test Chamber - Figaro

The SR-3 is a compact bench top test chamber for use in evaluation testing of gas sensors using test gases of various concentrations without an additional gas supply control system. The intended concentration of test gas can easily be prepared in the chamber using the volume method. Injected gas is mixed with air by the built-in fan to achieve uniform gas concentration throughout the chamber.
