High Accuracy and Stability: The sensor’s selective membrane technology ensures reliable oxygen detection with minimal drift over time, reducing recalibration needs in fluctuating conditions .
Low Maintenance Design: The robust POM housing and interchangeable membrane cap withstand corrosive media. Air calibration can be performed quickly without removing the sensor from the process, cutting downtime .
Long Service Life: The sealed reference electrolyte and durable electrode system provide consistent performance, even in high-load wastewater or industrial effluents, extending service intervals .
Flexible Integration: Compatible with Endress+Hauser transmitters (e.g., Liquisys COM253) via TOP68 connectors, enabling seamless data transmission for centralized control systems .
Harsh Environment Suitability: With IP68-rated connections and resistance to chemical exposure, the COS41-4F operates reliably in humid, dusty, or submerged conditions .
Wastewater Treatment Plants: Monitors and controls aeration tank oxygen levels to optimize biological degradation processes, reducing energy consumption .
Surface Water Monitoring: Tracks dissolved oxygen in rivers, lakes, or oceans to assess water quality and support environmental compliance .
Drinking Water Management: Ensures optimal oxygen levels in potable water systems to prevent corrosion and maintain safety .
Aquaculture and Fisheries: Maintains ideal oxygen concentrations in fish farms to promote healthy growth and prevent mortality .
Note: Specifications are based on manufacturer documentation and industry sources. Verify parameters against the latest technical guides for specific applications.
