The JUMO ecoLine O-DO is an optical sensor designed to measure dissolved oxygen in aqueous solutions. The sensor features excellent interference immunity thanks to the integrated preamplifier and digital signal processing. The measured value for dissolved oxygen is automatically compensated with the temperature, air pressure, and salinity (salt content), and transferred without interference to the connected indicating device and controller via a digital interface. 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. As a result, the Plug and Play function of the system is enabled without the need for recalibration. The sensor also includes a log book containing the last 10 successful calibrations in the form of a ring buffer.

• 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)
• Secure measured value display in combination with JUMO AQUIS 500 RS, JUMO AQUIS touch S and P, and JUMO mTRON T
• Low operating costs due to reduced maintenance requirements (no electrolyte changes and no polarization voltage)
• Greater calibration intervals due to lower drift behavior

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