This sensor utilizes an original AO2 CiTiceL electrochemical oxygen sensor probe, offering a full-scale 0-100%Vol measurement range. The electrochemical principle ensures strong anti-interference capability, high sensitivity, and a typical service life exceeding two years in air. The onboard signal conditioning circuitry digitizes the sensor output and provides multiple interface options.
Designed for durability, the sensor operates across a wide temperature range of -20°C to +50°C and 0-99% relative humidity (non-condensing). Its compact form factor and standard Gravity connector simplify integration into environmental monitoring systems, oxygen generators, and combustion analysis applications.
