Reliable Performance for Life-Support Applications
In scuba diving, oxygen sensors play a critical role in maintaining proper PO₂ levels. Therefore, accuracy and reliability are essential for diver safety.
Accordingly, AST O2 Sensors for Scuba Diving provide precise and consistent measurements. In addition, stable electrochemical technology ensures reliable PO₂ monitoring in both rebreathers and analyzers. As a result, divers can maintain safe breathing gas mixtures throughout their dives.
Direct Replacement Compatibility
To simplify maintenance, AST designs sensors as direct replacements for many common systems. Consequently, users can install them easily without modifying existing equipment.
For example, compatible models include:
Teledyne Analytical Instruments – R-22D, R-22S, R-17D, R33S, R33S1, R33D, R33D1
Analox – 9100-9212-5A/5AD, 9100-9212-94, 9100-0220-9B, 9121-0
Nuvair – UBS O₂ Stick, Model 9510, Model 9507
Vandagraph – R-17VAN, VN202
Analytical Industries Inc. – PSR-11-39-MD, PSR-11-39JD, AII-11-60, AII-11-75D, AII-11-75-PO2-D
Furthermore, AST supports many additional models, offering greater flexibility across platforms.
Proven O2 Sensor Technology
At the core of each sensor is an electrochemical micro fuel cell designed specifically for oxygen detection. Moreover, AST designs and manufactures these sensors in the USA. Therefore, users benefit from consistent quality and reliable performance.
In summary, AST scuba diving O₂ sensors combine accuracy, reliability, and compatibility. As a result, they support safe and confident oxygen monitoring in critical diving applications.
