The Endress+Hauser COS41-4F is an amperometric dissolved oxygen sensor from the Oxymax W COS41 series. Designed for continuous monitoring in water and wastewater applications, it features a robust POM body, G1" threaded process connection, and a 15-meter fixed cable. This sensor utilizes a 2-electrode system with a replaceable membrane cap and includes an integrated NTC temperature sensor for automatic compensation. The longer cable makes it suitable for deep tanks or distant junction boxes.
Low Maintenance Design: The replaceable membrane cap and stable electrode system ensure long service intervals and reduced lifecycle costs.
Simple Air Calibration: Supports easy one-point calibration in air (saturation calibration), eliminating the need for complex chemical zero solutions.
Robust Construction: The POM sensor body offers excellent chemical resistance against water, wastewater, and mild chemical environments.
Extended Cable Option: The 15-meter fixed cable accommodates installations in deep aeration basins or where the transmitter is remotely located.
Applications
Wastewater Aeration Control: Optimizing blower energy consumption by monitoring dissolved oxygen levels in activated sludge basins.
Surface Water Monitoring: Measuring oxygen content in rivers, lakes, and reservoirs for environmental compliance.
Aquaculture & Fish Farming: Maintaining optimal oxygen levels in fish ponds and hatchery tanks.
Industrial Process Water: Monitoring dissolved oxygen in cooling water systems and boiler feedwater.
