This industrial dissolved oxygen sensor monitors trace oxygen in high-purity water, boiler feedwater and power plant water systems.

Designed for low-level dissolved oxygen measurement, the sensor uses a polarographic electrode with a platinum cathode, silver/silver chloride anode and silicone rubber membrane. It detects oxygen concentrations as low as 0.1 µg/L at 20 °C, helping operators monitor water conditions in oxygen-sensitive processes.

A 316L stainless steel body and double-shielded 5 m cable suit industrial installations. Temperature compensation elements are available to match the connected analyzer. The sensor requires polarization before use and a continuous flow of sample water across the membrane.

Features

• Trace dissolved oxygen measurement for high-purity water applications
• Polarographic sensing with a platinum cathode and Ag/AgCl anode
• Silicone rubber membrane supported by steel gauze
• 316L stainless steel electrode body
• Double-shielded 5 m cable
• Temperature compensation options for compatible analyzers

Temperature compensation elements are available in Pt100, Pt1000, 22 kΩ and 2.252 kΩ configurations. Match the element to the connected analyzer's input requirements when ordering.

Where is this sensor used?
It is intended for trace oxygen monitoring in thermal power plants, demineralized water systems and boiler feed water.

How long does the sensor need to polarize?
The specified polarization time is more than 8 hours.

Does the sample need to flow?
Yes. The specified minimum sample velocity is 5 cm/s across the sensing membrane.

How do I select the temperature compensation element?
Match it to your analyzer's input requirements.
