Serinus® 44

Ammonia Analyser

The Serinus® 44 analyser delivers precise and reliable performance at excellent value. It uses proven chemiluminescence technology and an external thermal catalytic converter to measure NO, NO2, NOx, and NHin ambient air (LDL < 0.4 ppb, range 0 – 20 ppm). The Serinus® range of analysers has been designed using the experience and knowledge Acoem has gained from operating large air quality monitoring networks for more than 40 years. The result is a range of instruments that integrates seamlessly into continuous monitoring networks.
