Zetian - Model EM-5 -Flue Gas Analyzer (Cold-Dry)
EM-5 Flue Gas Analyzer is a self-developed gas analysis product for environment online monitoring and industrial online analysis. Based on Ultraviolet Differential Optical Absorption Spectroscopy (UV-DOAS) and Stoichiometric Algorithm (PLS), the analyzer can measure SO2, NO, NO2, O2, NH3, CO, CO2, Cl2, O3, H2S, HCl, CH3I, CH2O, etc. It owns advantages of high accuracy and reliability, low operating cost, fast response, wide measurement range and application range.

- Adopt UV-DOAS and PLS algorithm, low detection limit and small temperature drift.
- NOX content can be directly obtained by measuring NO and NO2.
- without NO2→NO converter not interfered by particulate matter, moisture and other factors.
- No optical moving parts, with high reliability, vibration has no effect on measurement.
