Serinus® 57

Total Reduced Sulfur Analyser

The Serinus® 57 Total Reduced Sulfur (TRS) analyser delivers precise and reliable performance at excellent value. It uses proven UV fluorescent radiation technology and an external thermal converter to measure TRS in ambient air (LDL < 0.3 ppb, range 0 – 2 ppm). TRS is measured by converting TS to SO2 using the external HTO-1000 converter and then measuring the resultant SO2 using the pulsed UV fluorescence technique.

Superior air quality monitoring for global environments

Air quality monitoring is increasingly important in today’s urban, industrial and rural areas. The Serinus® range of analysers has emerged through 40+ years of experience and knowledge gained from operating large air quality monitoring networks. The result is a superior portfolio of instruments that integrate seamlessly into continuous monitoring networks. They not only measure human exposure to pollutants but can be combined with trace/background monitoring as well as stack monitoring – thus becoming a vital tool for governments and organisations to track and abate air pollution and its effects on their immediate environment.
