AA428-210 CiTiceL AO2 oxygen sensor
The AA428-210 CiTiceL AO2 Oxygen Sensor provides accurate, stable oxygen measurement for industrial, medical, and environmental monitoring applications.
The AA428-210 CiTiceL AO2 is a high-precision electrochemical oxygen sensor designed to measure oxygen levels accurately and reliably in various gas detection and monitoring applications. Manufactured by City Technology, this sensor provides linear and stable output, ensuring dependable performance even in demanding environments.
The sensor operates using an electrochemical cell that produces a current proportional to the oxygen concentration in the sampled air. This allows for accurate and fast response detection across a wide range of oxygen levels—ideal for use in industrial safety systems, environmental monitoring, medical equipment, and combustion control applications.
The AA428-210 AO2 sensor is renowned for its long operational life, low cross-sensitivity to other gases, and stable zero and span characteristics, making it a trusted choice for OEM integration and instrumentation applications.
