1. SO₂ ultra low emission inspection technology

The flue gas pretreatment uses a permeable tube to remove water, avoiding S2 dehydration, reduction in the home process, use of a group of permeable tubes, instrumental analysis, and no reference gas. Double range switching: when the discharge reaches the standard, the loose measuring range of SO is 50mg/Nm³, and the tunable laser absorption spectrum is adopted.

2. NOx ultra low emission measurement technology

The NO detection range adopts 100mg/Nm³ to achieve precision inspection; when boiler emissions abnormally, it will automatically switch to the appropriate range, realizing the real-time monitoring on high concentrations of pollutants.

3. Dust, PM25 ultra-low emission measurement technology.

We continuous heat the flue gas to avoid the impact of wet smoke, and take large sampling flow, around 50 times the sampling measurement amount. This method has the advantages of integrated design, on-line continuous measurement, small amount of maintenance, high sensitivity probe, and the instrument unit are used for low concentration measurement.
