SRX-CT23 % Oxygen Sensor – Replaces Class B-3 and PSR-11-23

Advanced Sensor Technology

SRX-CT23 oxygen sensor for industrial process control, sensor can measure oxygen from 0.0% to 25% with quick response and great accuracy. SRX-CT23 is a drop-in replacement for Teledyne Class B-3, AII PSR-11-23 and Panametrics OX-3 % O2 sensors. Expected sensor life in air is 15 months. Response time, R90, is 13 seconds to a step change in oxygen concentration at any level. This sensor offers a good compromise between the sensor response and the life. Its proprietary electrolyte formulation ensures full utilization of Pb anode, thus providing longer life without signal drift and minimizing periodic calibration requirement. Sensor is designed, developed and manufactured in the USA.
