JUMO Optical Sensor for Dissolved Oxygen

Jumo ecoLine O-DO is an optical sensor for dissolved oxygen for measuring dissolved oxygen in aqueous solutions.

Applications: ETP Aeration, sewage treatment, drinking water control, fish farms and similar.


Tax /GST included

JUMO ecoLine O-DO - optical sensor for dissolved oxygen (DO) serves as an addition to existing JUMO systems by providing the DO concentration measurement feature. It is based on the visual measurement procedure (luminescence method). The device is durable, made out of stainless steel, is robust, with almost no need for maintenance. It can store the calibration data, making it ideal for dynamic measuring environments, such as sewage treatment, drinking water control, fish farms and similar. It operates across a measuring range from 0 to 20 mg/l and temperatures up to 60 °C
