Model AST-CT-12 Oxygen Sensor – Replaces Teledyne R-24MED, PSR-11-917-M2

AST-CT-12 Oxygen Sensor is designed for use in ventilators and other respiratory gas analysis applications. It utilizes galvanic micro fuel cell technology specifically engineered for oxygen measurement, thereby ensuring accurate and reliable performance.

Moreover, the AST-CT-12 serves as a direct drop-in replacement for several widely used oxygen sensor models, including Teledyne R-24MED, Envetec OOM202, City Technology MOX-9, AII PSR-11-917-M2, and Maxtec Max-12. As a result, users can integrate it seamlessly into existing systems without requiring modifications.

In terms of performance, the sensor provides a signal output of 12–16 mV in air, ensuring consistent and dependable readings. To maintain quality, each AST-CT-12 oxygen sensor is tested for gas leakage at 30 inches of water column pressure around the secondary sensor housing.

Furthermore, AST subjects every sensor to rigorous validation procedures, including output verification, 24-hour stability testing and gas leakage at 30 inches of water column pressure. Consequently, each unit meets strict performance and reliability standards prior to deployment.

In addition, the sensor incorporates a proprietary electrolyte formulation and a super-activated lead (Pb) anode structure. Together, these features maximize anode utilization, extend sensor life, and minimize signal drift. As a result, the sensor reduces the need for frequent calibration while maintaining long-term stability.

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 and again after 8 hours of continuous operation.
3. Always follow the instructions in the owner’s manual for proper calibration procedures.

It is important to note that this class of sensor does not currently have FDA approval; however, an application for FDA Premarket Notification remains under review.

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