A test system for gas sensors - ScienceDirect

Two test chambers have been developed, optimized for a small volume and a precisely defined gas stream. These test chambers simultaneously contain up to ten sensors of different types (semiconductor, dielectric, microbalance, etc.) and provide measurements of gas temperature and pressure. The exhaust gases are analysed by a dew-point mirror and an optional infrared gas analyser to check the gas combination and accuracy of gas concentration. Measurements with semiconductor sensors, …
