JUMO digiLine O-DO S10 Dissolved Oxygen Sensor

Name: JUMO digiLine O-DO S10 Dissolved Oxygen Sensor – Datasheet
Brand: JUMO

Description

Overview

JUMO digiLine O-DO S10 is an intelligent digital optical sensor for measuring dissolved oxygen (DO) in aqueous solutions, engineered to deliver precise, long-term stable measurement in fish breeding, sewage treatment plants, and other water and wastewater technology applications. Using the optical luminescence quenching measuring principle per ASTM D888-05, the JUMO digiLine O-DO S10 eliminates the electrolyte replenishment and frequent calibration burden associated with older electrochemical dissolved oxygen sensors.

Working closely with plant engineers in the region, Seven Star LLC proudly supplies the JUMO digiLine O-DO S10 dissolved oxygen sensor to water and wastewater treatment, aquaculture, and laboratory customers across Oman and the wider GCC. Every unit supplied through Seven Star LLC comes with manufacturer documentation and access to local technical support – supporting facility engineers and procurement teams in Muscat, Sohar, and Salalah who specify the JUMO digiLine O-DO S10.

Working Principle

The JUMO digiLine O-DO S10 measures dissolved oxygen using the optical principle of luminescence quenching: a light source inside the sensor cyclically illuminates a luminophore coating on the sensor cap, exciting it to a higher energy state. As the luminophore returns to its ground state, it emits fluorescent light that is detected by a photodiode; the presence of oxygen molecules collides with and quenches this luminescence, reducing the emitted signal in direct proportion to the surrounding oxygen concentration. Because no oxygen is consumed in this process and no minimum flow rate is required, the measurement remains stable and accurate even at low oxygen concentrations and in stagnant or slow-flowing water.

This optical measuring principle gives the JUMO digiLine O-DO S10 its defining maintenance advantage over electrochemical sensors: there is no anode to decompose and no electrolyte to replenish, and the sensor requires calibration far less frequently. The measured dissolved oxygen value is automatically compensated for temperature via an integrated NTC sensor, and can additionally be compensated for air pressure and salinity using external sensors, ensuring accurate readings across changing environmental conditions.

Engineering Design of the JUMO digiLine O-DO S10

The JUMO digiLine O-DO S10 covers a measuring range of 0 to 20 mg/l (or 0 to 200% saturation), with measuring accuracy of ±1% at 25°C and a fast response time of t90 < 60 seconds. The sensor body is constructed from PVC and PC materials suited to both fresh and salt water applications, with a sensor shaft diameter of 20 mm (30 mm threaded shaft) and an Rp 1″ process connection, and resists exposure to CO2, H2S, SO2, ethylene oxide, and gamma sterilization for demanding process environments.

Two interfaces are available for transmitting the measured value: a bus-compatible JUMO digiLine digital interface with RS485 Modbus RTU protocol, and an analog 4 to 20 mA two-wire current output, giving system integrators flexibility to connect to either digital automation platforms or legacy analog control loops. Configuration, parametrization, and calibration data, including a log book of the last 10 successful calibrations, are stored directly in the sensor’s electronics, and the JUMO DSM (Digital Sensor Management) software allows calibration and testing from a PC via USB. Self-diagnostic functions continuously monitor sensor condition and output warning or error messages upon detecting malfunctions, and the UV-stable sensor cap is easily replaceable when worn.

About brand

JUMO is the German maker of temperature sensors, process controllers, pressure transmitters and liquid analysis instruments. Moritz Kurt Juchheim founded it in Fulda in 1948 as M. K. Juchheim KG, making glass thermometers with six employees. The name JUMO comes from the founder's name. It is still a family company headquartered in Fulda, and the parent company has been called JUMO GmbH & Co. KG since 2003.

Seven Star LLC is an independent supplier in Muscat. We list JUMO RTD and thermocouple probes, thermowells, transmitters, controllers, recorders and water analysis instruments, and supply them to process plants, OEMs, HVAC contractors and water utilities in Oman and the GCC by type number.

Choosing a temperature sensor starts with the range and accuracy. A Pt100 RTD is accurate and stable from about -200 to 600 °C and is the usual choice in process plants. A thermocouple (type K or J, for example) covers much higher temperatures and responds faster but is less accurate. The wiring also matters: a 3-wire or 4-wire Pt100 connection cancels the resistance of the cable, while a 2-wire connection adds an error that grows with cable length. That is why a head-mounted transmitter is often fitted close to the sensor.

Where JUMO products are used

In Oman and the GCC, JUMO sensors and controllers are used in oil and gas and chemical plants, food and beverage production, plastics and metal heat treatment, HVAC and district cooling, water and wastewater treatment, swimming pools and marine applications.
