Applied Sensing Technologies (AST) offers a complete line of % O2 Sensors-Industrial solutions designed to meet the demanding requirements of industrial oxygen measurement. Because processes vary widely in oxygen concentration, AST provides multiple sensor models suitable for both low- and high-level % O₂ detection.
Designed for Accuracy and Longevity
When applications involve elevated oxygen concentrations, sensor durability becomes critical. Therefore, AST includes % O2 Sensors-Industrial models specifically engineered for oxygen purity measurement. In fact, selected sensors are designed to achieve an expected service life of up to two years in 100% oxygen environments. As a result, facilities benefit from longer replacement intervals and lower maintenance costs.
Moreover, AST % O2 Sensors-Industrial products deliver excellent signal stability and consistent output across a wide range of operating conditions. Whether integrated into oxygen generation systems, medical-grade oxygen verification equipment, or industrial process control systems, these sensors provide reliable and repeatable measurements.
Seamless Replacement Compatibility
In addition to original equipment applications, AST manufactures % O2 Sensors-Industrial models as direct replacements for numerous analyzer brands. This ensures quick installation without system modification and minimizes downtime during maintenance.
Replacement sensors are available for:
Teledyne Analytical Instruments – Class B-1, B-3, C-3, A-5, E-2
Analytical Industries Inc – GPR-11-32-RTS, GPR-11-60-RTS, GPR-11-120, GPR-11-120-OP, GPR-11-120-RTS, GPR-11-120-4, XLT-11-24
Because these sensors function as drop-in replacements, users maintain analyzer performance while upgrading to AST’s proven technology.
Proven Oxygen-Specific Technology
At the core of every % O2 Sensors-Industrial product is an industry-proven electrochemical micro fuel cell designed exclusively for oxygen measurement. AST designs, develops, and manufactures these sensors in the USA, maintaining strict quality control and ensuring long-term reliability.
Ultimately, AST’s % O2 Sensors-Industrial line combines measurement flexibility, extended service life, and broad compatibility—providing dependable oxygen monitoring solutions across diverse industrial applications.
