APPLIED SENSING TECHNOLOGIES % Oxygen Sensor Model: SRX-CA120-RTS SRX-CA12-RTS Oxygen Sensor is a galvanic type micro fuel cell specific to oxygen. Proprietary electrolyte formulation and unique anode structure ensures full utilization of Pb anode, thus providing longer life in 100 % oxygen without signal drift and minimizing frequent calibration requirement. Expected sensor life in air 10 years. Sensor is designed, developed and manufactured in the USA.

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, after calibration with 100% oxygen. 3. At ambient temperature and pressure, and oxygen content upto 100%. 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.
