Technical overview
AST Model SRX-CT-2 Oxygen Sensor, a galvanic type micro fuel cell is specific to oxygen. It replaces Teledyne Model R-17MED, City Technologies Model MOX-2, IT Gambert Model M-15M, AII Model PSR-11-917-J and Envetec Model OOM102-1. The sensor has a 3.5mm mono jack connection, and M16x1 threaded front. Each AST Model SRX-CT-2 oxygen sensor is tested at 30 inches of water column pressure for any gas leakage. Proprietary electrolyte formulation, super activated anode and the unique anode structure ensure full utilization of Pb anode, thus providing longer operating life without significant signal drift thus minimizing frequent calibration requirement. A premarket notification application to FDA has been submitted and is currently under review. AST brand sensors are designed, developed and manufactured in the USA.
Applications and guidance
Advanced Sensor Technology
Model AST-CT-2 Oxygen Sensor
The Model AST-CT-2 Oxygen Sensor utilizes galvanic micro fuel cell technology specifically engineered for oxygen measurement, thereby ensuring accurate and dependable performance in critical applications.
Moreover, the AST-CT-2 serves as a direct replacement for several widely used models, including Teledyne R-17MED, City Technology MOX-2, IT Gambert M-15M, AII PSR-11-917-J, and Envetec OOM102-1. As a result, users can integrate this sensor into existing systems without requiring modifications.
In terms of design, the sensor features a 3.5 mm mono jack electrical connection along with an M16x1 threaded front, which simplifies installation and ensures secure mechanical fitment.
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.
Furthermore, the sensor incorporates a proprietary electrolyte formulation, a super-activated anode, and a uniquely engineered anode structure. Together, these features maximize utilization of the lead (Pb) anode, extend operational life, and minimize signal drift. As a result, the sensor reduces the need for frequent calibration while maintaining long-term stability.
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.
- Follow the instructions in the Owner’s Manual for calibration of the sensor
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.
