Product details
Technical overview
AST-60D Oxygen Sensor replaces AII-11-60 in AII-3000A and AII-3000M analyzers. AST-60D is a galvanic type micro fuel cell specific to oxygen. Expected sensor life is 60 months in air at ambient temperature and pressure. Its innovative design with proprietary Pb anode structure provides with excellent stability and ensures full utilization of the anode without signal drift thus minimizing frequent periodic calibration requirement. Sensor is designed, developed and manufactured in the USA.
Applications and guidance
Advanced Sensor Technology
The AST Model AST-60D % Oxygen Sensor is designed for accurate measurement of oxygen from low percentage up to 100% . This sensor utilizes galvanic micro fuel cell technology specifically engineered for oxygen, thereby delivering reliable and stable performance.
The AST-60D % oxygen sensor serves as a direct replacement for Analytical Industries AII-11-60 % oxygen sensors. As a result, users can integrate it seamlessly into existing systems, including the model AII-3000 and AII-3000A oxygen analyzers, without requiring any electronics modifications. The signal output from the oxygen sensor is supplied via a phone jack. The front end of the sensor has M16x1 thread for easy mounting.
The sensor also contains a medium level of the anode material but still provides an extended operating life of up to 60 months in air under ambient temperature and pressure. Consequently, users benefit from longer service intervals and reduced maintenance requirements.
The sensor incorporates a super-activated anode with a unique structure, which enhances linearity, accuracy, and overall stability. Furthermore, its proprietary lead (Pb) anode structure maximizes anode utilization while minimizing signal drift. As a result, the sensor maintains consistent performance even under varying ambient conditions and reduces the need for frequent span calibration.
To ensure reliability, AST subjects every sensor to rigorous validation procedures, including output verification and 24-hour stability testing. Consequently, each unit meets strict performance and quality standards prior to deployment.
CAUTION:
- Users must verify compatibility of the AST oxygen sensor with their intended equipment before installation.
- Although the sensor offers enhanced stability, users should calibrate it before use.
- Always follow the instructions in the owner’s manual of the intended analyzer for proper calibration procedures.
AST designs, develops, and manufactures its sensors in the United States, thereby ensuring high standards of quality, consistency, and reliability
