Product Description
EM-5 UV Online Flue Gas Analyzer NOx, SOx, CO2, CO, O2
Pls visit our web:
EM5 series stack gas analyzers are independently developed by Hangzhou Zetian Technology Co., Ltd., based on years of experience in research and development, for domestic and overseas environmental and
industrial control site monitoring online analysis. Based on DOAS and chemometric algorithms (PLS) , this analyzer can measure SO2, NO, NO2, O2 , NH3, Cl2, O3 , H2S and etc.With high accuracy and reliability, fast response time, wide selfdeveloped and industrial 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.
Technical Principle
EM-5 flue gas analyzer applies UV DOAS technology. The optical technology platform consists of
light sources, gas chamber, optical and spectroscopic (including diaphragm, holographic grating, linear array detector) and other optical components.
Ultraviolet light is sent by the light source through the optical window into gas chamber; absorbed by the sample gas through the gas chamber. The light carrying sample absorption information gathers through lens coupled into fiber and then transmits through the optical fiber into spectrometer. After light splitting and photo-voltaic, conversion, absorption spectrum is obtained and analyzed to calculate the concentration of the related components in gas.
Technical Features
- High measurement accuracy
- The minimum detection limit of SO2 , NO2, NO can be 1mg/m2
- No moisture absorption by ultraviolet , avoiding disturbed by moisture and dust
- No cross interference between the gas being measured (see table 1).
- Directly measure NO2 and NO without NO2 → NO converter
- Low detection limit
- High reliability
- Low zero drift and span drift
- Modularization design
- No optical moving parts and resist to vibration
- Strong gas chamber, saving cost
- Spectrum automatic adjustment technology
- Free from maintenance for long period
- Adopts the pulse source for light source with 10-year service life
