The Serinus 10 Ozone (O3) analyser delivers precise and reliable performance at excellent value. It uses proven non-dispersive ultraviolet (UV) absorption technology to measure O3 in ambient air (LDL <0.5ppb, range 0-20ppm).


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.
