Cubic-Ruiyi (a wholly-owned subsidiary of Cubic sensor) independently developed Gasboard 3800GHG portable greenhouse gas emission analyzer.

Adoptting the independent intellectual property rights of Micro flow NDIR dual-chamber sensor technology (international PCT patent PCT/CN2018100767), Cubic-Ruiyi portable greenhouse gas emission analyzer Gasboard 3800GHG can accurately measure the greenhouse gases concentration change of CO2, CH4, N2O etc and CO gas in flue gas at the same time. The range can be as low as 200ppm, the accuracy can be as high as 1%F.S.. Besides it has strong resistance to gas cross interference and low drift. Equipped with integrated sampling probe and heat tracing device, portable pretreatment device, and also expand the measurement indicators of flue gas temperature, pressure, flow rate and others, Gasboard 3800GHG greenhouse emission gas analyzer could achieve the emission rate and emission total statistics;

At the same time, for high concentration of CO2 and high range CO measurement, NDIR gas sensor technology sensor modules with intellectual property rights are optional for flexible configuration. Good stability, small size and low cost.
