COS61-A2F0 belongs to Endress+Hauser Oxymax COS61 optical dissolved oxygen sensor family. Adopting luminescence quenching principle, it realizes stable DO measurement with low maintenance requirement. Integrated NTC temperature sensor for automatic temperature compensation. Max working pressure 10 bar, operating temperature range -5 ~ +60℃.

Digital signal output for connection to E+H liquid analysis transmitters. The order code definition: A = non-explosion-proof, 2 = 15m fixed cable, F = G1 thread, 0 = no additional accessories. It supports automatic sensor check function to detect membrane aging and contamination. Wetted materials resist corrosion in water and wastewater environments. Protection class IP68 when fully submerged.

COS61-A2F0 is obsolete E+H dissolved oxygen sensor spare part. Many legacy water treatment sites still adopt this sensor with COM series transmitters. When the original sensor fails, replacement with identical COS61-A2F0 can reuse transmitter, mounting assembly and original calibration parameters. Technicians install the sensor, perform calibration and test signal communication, so dissolved oxygen online monitoring system resumes operation and reduces downtime.

Before shipment, every COS61-A2F0 undergoes comprehensive functional inspection including optical membrane check, temperature test, digital communication verification and pressure tightness test. All products come with 12-month warranty. Our automation technical team provides remote support for installation, wiring guidance, calibration and fault diagnosis. Fast global shipping available for urgent maintenance orders.

For automation maintenance engineers and system integrators, COS61-A2F0 is reliable spare optical dissolved oxygen sensor for legacy Endress+Hauser water analysis systems. It restores online dissolved oxygen measurement, extends service life of water treatment assets and avoids whole analytical system renovation.
