Applications and guidance

Advanced Sensor Technology

Model SRZ-CA24-4 % O2 Sensor

The Model SRZ-CA24-4 % O2 Sensor is designed for accurate oxygen measurement in a variety of gas mixtures. Utilizing advanced galvanic sensor technology, it delivers reliable and stable %O₂ readings across demanding applications.

Moreover, the SRZ-CA24-4 % O2 Sensor serves as a direct drop-in replacement for Analytical Industries XLT-11-24 % O₂ sensors as well as AII Model OXY P24-2-4 % oxygen sensors. As a result, users can integrate it seamlessly into existing systems without requiring modifications.

In addition, the sensor features an electro-etched sensing cathode that creates an exceptionally smooth surface. This design enhances signal stability and ensures consistent performance over time. Furthermore, its proprietary electrolyte formulation provides excellent compatibility with gas mixtures containing varying levels of acidic CO₂.

The sensor also incorporates a super-activated anode with a unique geometry, which improves linearity, accuracy, and overall stability. Moreover, its proprietary lead (Pb) anode structure maximizes anode utilization while minimizing signal drift. Consequently, the sensor maintains reliable performance even under changing 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. As a result, each unit meets strict performance and quality 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.
