Serinus 55 Hydrogen Sulfide (H2S) Analyser

Ambient & Trace Monitor SO2

Category: Tag:


The Serinus 55 Hydrogen Sulfide analyser (H2S) analyser delivers precise and reliable performance at excellent value. It uses proven UV fluorescent radiation technology and an internal thermal catalytic converter to measure H2S in ambient air (LDL <0.3 ppb, range 0-2 ppm).

The Serinus range of analysers has been designed using our experience and knowledge gained from operating large air quality monitoring networks for more than 35 years. The result: instruments that integrate seamlessly into continuous monitoring networks.
