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
