Vasthi online monitoring stack gas analyzer (OMGA-2000 DOAS) is a one-site installation stack gas analyzer that is developed after years of teaching and design on online gas analysis instruments. It can monitor gas parameters, including the concentration of SO2, NOx, O2, dust, humidity, temperature, pressure, flow and etc. Vasthi online monitoring stack gas analyzer is mainly applied to tail gas emission monitoring process analysis in many fields including a coal-fired power plant, waste-to-energy plant, cement factory, glass factory, lime factory, ceramics factory, sinter, coke oven, DeSOx process, and DeNOx process.

Vasthi online monitoring stack gas analyzer adopts 150˚C high-temperature heat tracing for the whole process, on-site filtering and sampling, on-site analysis, and measuring technology. All paths contacting with gas are made of 316L stainless steel. This gas analyzer has many transcendent features, such as low detection limit, accurate measuring result, easy to calibrate and compare with simple construction and without any moving parts.
