AST Model SRX-CA32-4 % O2 Sensor

The AST Model SRX-CA32-4 % O2 Sensor is designed for measuring oxygen in a wide range of inert gases and gas mixtures containing up to 0.1% CO₂. Utilizing advanced galvanic sensor technology, it delivers accurate and reliable %O₂ measurements across demanding applications.

Moreover, the SRX-CA32-4 % O2 sensor serves as a direct replacement for GPR-11-32-4 % Oxygen Sensors as well as Analytical Industries Model OXY-P25-1-4 % O₂ sensors. As a result, users can integrate it seamlessly into existing systems without requiring modifications.

The sensor also features a super-activated anode with a unique geometry, which enhances linearity, accuracy, and overall stability. Furthermore, its proprietary lead (Pb) anode structure ensures maximum 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. The sensor has a T90 response time of 6 sec and still offering 32 months of operating life at ambient temperature and pressure.

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 reliability standards prior to deployment.

CAUTION:

  1. Users must verify compatibility 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.
