SRX-CA120-4 % Oxygen Sensor for O2 Purity Analysis – Replaces GPR-11-120-4 O2 Sensor

The AST Model SRX-CA120-4 Oxygen Purity Sensor is designed for accurate oxygen purity measurement. This sensor utilizes galvanic micro fuel cell technology specifically engineered for oxygen, thereby delivering reliable and stable performance.

The SRX-CA120-4 % oxygen purity sensor serves as a direct replacement for Analytical Industries GPR-11-120-4 oxygen purity sensors. As a result, users can integrate it seamlessly into existing systems, including the model GPR-3100, GPR-3100MO and GPR-1200MO oxygen purity analyzers, without requiring any electronics modifications.

In addition, this sensor has lower signal output in air and hence is suitable for higher levels of oxygen. The sensor also contains a larger amount of the anode material that provides an extended operating life of up to 120 months in air under ambient temperature and pressure. Consequently, users benefit from longer service intervals and reduced maintenance requirements even when used to measure elevated levels of oxygen.

The sensor also incorporates a super-activated anode with a unique geometry, which enhances linearity, accuracy, and overall stability. Furthermore, its proprietary lead (Pb) anode structure maximizes anode utilization while minimizing signal drift. As a result, the sensor maintains consistent performance even under varying ambient conditions and reduces the need for frequent calibration.

To ensure reliability, AST subjects every sensor to rigorous validation procedures, including output verification and 24-hour stability testing. Consequently, each unit meets strict performance and quality standards prior to shipment.

CAUTION:

1. Users must verify compatibility of the AST oxygen sensor with their intended equipment before installation.
2. Although the sensor offers enhanced stability, users should calibrate it before use.
3. Always follow the instructions in the owner’s manual of the intended analyzer for proper calibration procedures.

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