APPLIED SENSING TECHNOLOGIES % Oxygen Sensor Model: SRX-CT21 SRX-CT21 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 providing 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 operating temperature uder 35°C, atmospheric pressure and oxygen content in sample gas less than 21% 4. AST warrants the sensor for 9 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.
