Technical overview
AST Model SRX-CT-4 % oxygen sensor replaces Teledyne T-7 and City MOX-4 O2 sensors. SRX-CT-4 % oxygen sensor is designed for measuring oxygen in ventilators for respiratory gas analysis. This %O2 sensor is a drop-in replacement to Teledyne Model T-7, City Technology Model MOX-4, IT Gambert Model M-07 and AII Model PSR-11-77 %O2 sensors. This sensor shows excellent linearity and accuracy even under varying ambient conditions. AST Model SRX-CT-4 O2 Sensor is primarily used in Teledyne analyzers Model TED 191T, TED 200T, TED 200T7, TED 60J, and TED 60T analyzers. This sensor has a built-in temperature compensation circuit. Its innovative design with proprietary and supper activated Pb anode structure provides with excellent stability and ensures full utilization of the anode without signal drift thus minimizing frequent calibration requirement. Sensor is designed, developed and manufactured in the USA.
Applications and guidance
Advanced Sensor Technology
AST-CT-4 Oxygen Sensor is specifically designed for measuring oxygen in ventilators and respiratory gas analysis applications. Utilizing advanced galvanic sensor technology, it delivers accurate and stable % O₂ measurements even under varying ambient conditions.
Moreover, the AST-CT-4 oxygen sensor serves as a direct drop-in replacement for several widely used models, including Teledyne T-7, City Technology MOX-4, IT Gambert M-07, and AII PSR-11-77 O₂ sensors. As a result, users can easily integrate it into existing systems without requiring modifications.
In addition, this sensor is widely used in Teledyne analyzers, including models TED 191T, TED 200T, TED 200T7, TED 60J, and TED 60T. Its built-in temperature compensation circuit further enhances measurement accuracy by maintaining consistent performance across changing environmental conditions.
Furthermore, the AST-CT-4 oxygen sensor features a proprietary electrolyte formulation and a super-activated lead (Pb) anode with an optimized structure. Together, these innovations ensure full utilization of the anode, improve stability, and minimize signal drift. Consequently, the sensor reduces the need for frequent calibration while maintaining long-term reliability.
To ensure consistent quality, AST subjects each sensor to rigorous testing, including output verification, 24-hour stability testing, and gas leakage testing at 30 inches of water column pressure. Consequently, every unit meets strict performance and reliability standards prior to deployment.
CAUTION:
- Users must verify compatibility with their intended equipment before installation.
- Although the sensor offers enhanced stability, users should calibrate it before use and again after 8 hours of continuous operation.
- 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.
