APPLIED SENSING TECHNOLOGIES PPM Oxygen Sensor Model: SRZ-MA100-4 SRZ-MA100-4 PPM 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, very low noise and drift. This sensor, with its proprietary electolyte formulation, offers excellent compatibility with acid gases such as CO2 in any concentration. This sensor is designed, developed and manufactured in the USA.

Use sensor immediately after removing it from the sealed bag. After removing, do not leave sensor in air for extended period of time. Failure to do so may have negative impact on its performance and operating life. 1. Signal Output measured in air at 25°C and at atmospheric pressure. 2. At constant temperature and pressure. 3. At operating temperature less than 35°C, atmospheric pressure and oxygen content in sample gas less than 10,000 ppm. 4. AST warrants the sensor to be free from defects in materials and workmanship. AST will not be held liable for sensor damaged due to customer neglect and misuse. * Specifications are validated during design and are subject to change without notice.
