APPLIED SENSING TECHNOLOGIES PPM Oxygen Sensor Model: SRZ-MA333 SRZ-MA333 PPM Oxygen Sensor is a galvanic type micro fuel cell specific to oxygen and is a direct replacement to Analytical Industries Model XLT-12-333. Proprietary electrolyte 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. 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 life. 1. Signal Output measured in air at 25°C and at atmospheric pressure. 2. At constant temperature and pressure. 3. At operating temperature uder 35oC, atmospheric pressure and oxygen content in sample gas less than 1,000 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.
