DOAS Flue Gas Analyzer, Online Monitor SO2, NOx

Product Description

Product description
EM*5 flue gas analyzer is a self-developed gas analysis product for domestic and overseas environmental and industrial on-line monitoring online analysis. 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.It can be widely used in environmental online monitoring, industrial process control, safety monitoring, etc.

Features
1. Low detection limit and temperature-drift
2. Getting NOx by directly measuring NO and NO without NO →NO2 converter
3. No interference of particulate matter, moisture and other factors
4. No optical moving parts, high reliability, no interference to the measurement by field
