JAS767906AA is a standard gas flow hood designed for use with SGX VQ500 series pellistor sensors, infrared mini-sensors, and electrochemical non-reactive gas sensors. This accessory is intended to be used with the ECVQ-EK3 evaluation kit and compatible gas sensor evaluation systems. The hood provides controlled gas flow conditions for accurate sensor testing and measurement. It is suitable for applications involving non-reactive gases, making it ideal for laboratory testing, sensor characterization, and instrument development. For applications involving reactive gases such as H2S, NO2, Cl2, ClO2, or ETO, the premium gas flow hood JAS769638AA is recommended instead.
