The Serinus 30 Carbon Monoxide analyser delivers precise and reliable performance at excellent value. It uses proven NDIR gas filter correlation technology to measure CO in ambient air (LDL <40 ppb, range 0-200ppm).


The Serinus range of analysers have been designed using Ecotech's 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.
