DOAS UV So2 NO NO2 O2 Gas Analyzer for CEMS>>OverviewThe AG-UVll3 flue gas analyzer consists of components such as
alight source, gas chamber, spectrometer, HMl module,
interfaceboard,temperature sensor, electrochemical oxygen sensor,
andexpandable modules.
Based on conventional Differential Optical Absorption
Spectrosco-py(DOAS), the analyzer processes spectral data using the
PartialLeast Squares(PLS)algorithm.The combined measurementchamber
design offers high accuracy, powerful functionality, andeasy
maintenance.lt integrates a high-performance microproces-sor, with
embedded software that enables signal processing, datacalculation,
real-time monitoring, and functions such as keyboardoperation,LCD
display,alarms,and settings in the human-ma-chine interface.
>>Feature
1. Multi-pass gas chamber design for extended optical path and
ultra-low gas concentration detection.
2. Low drift, high precision, low power consumption. fast response.
3. High-performance UV xenon lamp with long lifespan and
vibration-resistant design.
4. Modular desian for liaht source, detector, and core circuit,
ensuring hiah reliability, scalability, and easy maintenance.
