Product Description

EM-5 continuous online flue gas analyzer, monitor SO2, NO, NO2, CO, CO2, O2, high precision

EM-5 continuous online flue gas analyzer is suitable for online gas analysis of environmental protection and industrial control sites.  Based on UV Differential Optical Absorption Spectroscopy (DOAS) technology, and Non-Dispersive Infrared (NDIR) technology, chemometrics algorithm (PLS). 

The analyzer is able to measure the components SO2, NO, NO2, CO, CO2, O2,  other gas components like NH3, Cl2, H2S can also be measured through configuring modules. One analyzer can measure 5 gas components at a maximum.  The analyzer is featured with high measurement accuracy and reliability, fast response and wide application. 

Applications

•    Continuous flue gas emission monitoring for power plants c (SO₂, NOx, and O₂);

•    Continuous flue gas emission monitoring of waste incineration (SO₂, NOx and O₂)

•    DeSOx process monitoring (SO₂ and O₂)

•    DeNOx process monitoring (NOx, NH₃ and O₂)

•    Trace Cl₂ analysis in PVC process and titanium dioxide production process in chlor-alkali plants (Cl₂)

•    Gas analysis in sulfur recovery process (H₂S)

•    Methyl iodide analysis in coal chemical industry (CH₃I)

•    Online ambient air monitoring (SO₂, O₂), etc. 

Features

•      Adopt Ultraviolet Differential Optical Absorption Spectroscopy (UV-DOAS) + Non-Dispersive Infrared (NDIR) technology.  Long range gas chamber with high sensitivity. 

•      NO and NO2 can be directly measured at the same time without converters. 

•      High stability, high measurement accuracy. 

•      Not affected by background components including H2O, CH4, CO, NH3, dust, etc.

•      Not affected by temperature vibration. 

•      No moving parts and, not affected by vibration.

•      No cross interference between measured gases. 

•      The pulsed xenon light source has a long service life. 

•      Low detection limit, minimum detection limit of SO2, NO, NO2 can reach 1mg/m3 (15m optical path)

Function
Automatic span calibration (customizable)	•  Periodic auto calibration based on the preset cycle    Automatic calibration cycle setting range:1~60,000 hours •  Injection time of each calibration gas can be set during automatic calibration.    Pre-purge time and post-purge time:1~300s.
Zeroing	•  Periodic auto calibration based on the preset cycle    Automatic calibration cycle setting range:1~60,000 hours •  Injection time of each calibration gas can be set during automatic calibration.    Pre-purge time and post-purge time:1~300s.
Upper and lower limit alarm	The alarm will be trigged when the measured value reaches upper and lower alarm limits. The analyzer will send alarm signals when the measured concentration of each component is beyond the preset upper/lower alarm limit.
