APPLIED SENSING TECHNOLOGIES PPM Oxygen Sensor Model: SRZ-MGP-41A SRZ-MGP-41A 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. Proprietary electolyte formulation offers excellent compatibility with sample gas containing acid gases such as CO2, traces levels of H2S and SO2. Sensor is designed, developed and manufactured in the USA.

Use sensor immediately after removing from the sealed bag. Do not leave sensor in air 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 and at atmospheric pressure. 2. At constant temperature and pressure. 3. At operating temperature under 35oC, atmospheric pressure and oxygen content in sample gas less than 10,000 ppm. 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 or misuse. * Specifications are validated during design and are subject to change without notice.
