- Model AM-5100 - SO2 Analyzer System



SO2 analyzer adopts ultraviolet fluorescence method and combines with advanced microprocessor technology. It provides accurate and reliable detection of SO2 at ppb~ppm level which meets the requirements of ambient gas monitoring and online monitoring of pollution source with dilution method. The operation principle is based on ultraviolet fluorescence method. After absorbing the ultraviolet energyg, SO2 molecule is inspired to excited state and once it returns to ground state, it will release specific fluorescence. The intensity of fluorescence could realize quantitative measurement.

Measurement stability is greatly improved by using timed dark current measurement to compensate photomultiplier drift and reference detector to calibrate the change of UV light intensity. With high-efficiency hydrocarbon remover and unique optical design the analyzer can effectively clear up inexactitude caused by interference. This analyzer can completely control all functions and also provides online instruction for important work parameters. Real time auto compensation for temperature and pressure will be made during measurement.
