APPLIED SENSING TECHNOLOGIES % Oxygen Sensor Model: SRX-CT23 SRX-CT23 Oxygen Sensor is a galvanic type micro fuel cell specific to oxygen. Its innovative design with electro-etched sensing cathode provides with extremely smooth sensing surface for excellent signal stability. Proprietary electolyte formulation ensures full utilization of Pb anode, thus providind longer life without signal drift and minimizing periodic calibration requirement. Sensor is designed, developed and manufactured in the USA.

Do not expose sensor to temperatures above 50o C for extended period of time. Failure to do so may have negative impact on its performance and life. 1. Signal Output measured in air at 25°C at atmospheric pressure. 2. At constant temperature and pressure. 3. At ambient temperature and pressure. 4. AST warrants the sensor for 12 months to be free from defects in materials and workmanship. AST will not be held liable for sensor damaged due to customer neglect. * Specifications are validated during design and are subject to change without notice.
