Smart amperometric Ozone Analyser: 9185 sc
The 9185sc Ozone Sensor is an online, single-channel industrial sensor that measures ozone in drinking water treatment plants, distribution networks, and other applications that require monitoring of ozone at the ppb and ppm levels. This instrument uses an amperometric method to measure ozone concentration. A membrane allows the selective diffusion of ozone molecules to the amperometric sensor. The measurement is compensated for pH and temperature.
