Cubic-Ruiyi Gas Modules Gasboard-2108 series is suitable for automobile exhaust emission monitoring and environmental monitoring, meeting gasoline vehicles emission measurement standard of GB 18285-2018.
Adopting the high-precision dual-beam infrared gas analysis technology of independent intellectual property rights to measure the concentration of CO, CO2, and HC, and the international PCT patent (PCT/CN2018100767) micro-flow infrared dual-gas chamber technology to measure the concentration of NO, the Gasboard-2108 has good anti-interference and high accuracy performance.
Infrared dual-gas chamber technology is an advanced measurement methods. The measured gas and the reference gas are in separate two chambers. When the infrared light source irradiates the measured gas and the reference gas respectively, the signal waveform formed by detector is passed through the signal processing system to obtain the measured gas concentration through the ratio value.
