Long-Term Stability, Low-Drift, and Low Maintenance - The JUMO ecoLine O-DO optical sensor – an 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 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 characterized 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. This makes it easy to use Plug and Play without the need for recalibration. The robust sensor in a stainless steel case (D 25 mm x 124.5 mm) operates across a measuring range from 0 to 20 mg/l and can be used in a temperature range from 0 to 60 °C. Immersion and flow fittings are available as accessories.


Luminous display makes readings easier
The sensor is connected to the JUMO AQUIS 500 RS transmitter with integrated controller function via Modbus RTU protocol RS 485. The transmitter is designed as a field device with protection type IP 67 for use on site; however, it can also be mounted in a control cabinet if required. Plain text displays make the operation easier – the backlight enables readings to be taken even in adverse lighting conditions.

The device is programmed via a PC using a convenient setup program that is available as an accessory. The transmitter is equipped with two relays that enable the user to implement switching, monitoring, and control tasks.
The JUMO AQUIS 500 RS complements the proven AQUIS 500 series, which already contains devices for measuring pH value, redox potential, conductivity, and ammonia concentration.
