SRZ-MT12 PPM O2 Sensor – Replaces Teledyne A-2C PPM O2 Cell

SRZ-MT12 PPM O2 Sensor replaces the Teledyne Class A-2C and AII Model XLT-12-123. SRZ-MT12 is designed for precise trace oxygen measurement in low PPM applications. Utilizing advanced galvanic sensor technology, it delivers accurate, stable, and reliable performance in demanding environments.

Moreover, the SRZ-MT12 PPM O2 Sensor serves as a direct replacement for several widely used models, including Teledyne Class A-2C, Part number C06689-A2C, Analytical Industries Model XLT-12-123, AMI Models T-2 and T-4, and GE Panametrics Model  OX-2 PPM O₂ sensors. As a result, users can integrate it seamlessly into existing systems without requiring modifications.

In addition, the sensor features a proprietary electrolyte formulation that provides excellent compatibility with sample gases containing acidic components such as CO₂, as well as trace levels of H₂S and SO₂. Consequently, it maintains reliable performance even in challenging gas compositions.

To ensure consistent quality, AST gas-tests all sensors for stability, accuracy, and recovery from ambient air to low PPM oxygen levels. As a result, each unit meets strict performance standards prior to use.

Furthermore, AST packages each sensor in Dry-Shield® metallized moisture barrier bags filled with nitrogen to protect against environmental exposure. Therefore, users should install the sensor immediately after opening the package. Prolonged exposure to ambient air will significantly reduce sensor life and performance.

CAUTION: The recommended storage period of SRZ series sensors is 3 months from the date of shipment. The sensor must be stored at ambient temperature and pressure, away from direct sun. Longer storage period may effect the performance of the sensor.

Finally, AST designs, develops, and manufactures all of its sensors in the United States, thereby ensuring high standards of quality, consistency, and reliability.
