JUMO 202613 Optical Sensor for Dissolved Oxygen

100 in stock


JUMO eco Line O-DO optical sensor for dissolved oxygen for measuring dissolved oxygen in fluid arrangements and serves in as an expansion to existing JUMO frameworks by giving the DO content. The optical membrane cap is easy to replace, meaning the sensor is very easy to maintain. The current calibration data is saved directly in the sensor electronics.

Applications: Municipal and industrial sewage treatment plants, Drinking water monitoring, Water protection, Fish farming companies, Process plants

JUMO Optical Sensor for Dissolved Oxygen can store the alignment information, making it perfect for dynamic estimating situations, for example, sewage treatment, drinking water control, angle ranches, and comparable. It works over a measuring range from 0 to 20 mg/l and temperatures up to 60 °C. It depends on the visual estimation system (radiance technique). The device is solid, made out of hardened steel, is vigorous, with no requirement for support.

Features of UMO ecoLine O-DO – Optical Sensor :

  • Suitable for indicating device/controller according to T202569
  • Greater calibration intervals due to lower drift behavior
  • High measuring accuracy even for low concentrations
  • Short response time
  • No minimum inflow (no oxygen consumption)
