- Model EM-5UL - Ultra low emission flue gas analyzer, on-line analyzer, SOx, NOx, CO, CO2, O2

0
EM-5 flue gas analyzer is a self-developed gas analysis product of multiple return light path. The analyzer is based on DOAS and chemometric algorithms (PLS), able to measure SO2, NO, NO2, O2, NH3, CO, CO2, Cl2, O3, H2S, HCl, CH3I, etc. With high accuracy and reliability, low operating costs, fast response time, wide measurement range and application fields, it has achieved even surpassed similar products home and abroad. Features - Low detection limit and temperature-drift - Getting NOx by directly measuring NO and NO2 without NO2→NO converter - No interference of particulate matter, moisture and other factors - No optical moving parts, high reliability, no interference to the measurement by field vibration Using return light path and high quality spectrograph, the minimum measuring range is 0-20ppm, - Lowest detection limit is 200ppb

Apply to exhaust emission monitoring and process control such as coal-fired power plants, garbage power plant, cement, glass, lime factory, ceramics factory, sinter, coke oven, desulfurization, denitration technology and etc.
