Intelligent Measuring System for Dissolved Oxygen

In addition to measuring the pH value and conductivity, determining the concentration of dissolved oxygen is an important task in aqueous analytical measurement. For this purpose, JUMO (Germany) presents the ecoLine O-DO – a new digital sensor based on a visual measurement procedure (luminescence method). Unlike conventional electrochemical sensors, the optical sensor is characterised by a measurement that is low-drift, low-maintenance, and has great long-term stability. It is suitable for use in communal and industrial sewage treatment plants, drinking water monitoring, water protection, fish farms, and other applications.

The JUMO ecoLine O-DO saves the calibration data and calibration history straight to the head of the sensor. The robust sensor in a stainless steel case operates across a measuring range from 0 to 20 mg/l and can be used in a temperature range from 0 to 60 °C.
