Fluorescent Oxygen Sensor, 0-25%/0-300mbar/500-1200mbar

Purchase industrial fluorescent oxygen sensors utilizing non-contact optical principles to effectively prevent electrochemical drift. The oxygen sensor detects oxygen concentrations from 0 to 25%, partial pressure ranges from 0 to 300 mbar, and atmospheric pressure ranges from 500 to 1200 mbar. It maintains stable operation across a wide temperature and humidity range (10°C to 45°C, 0% to 99% RH).

Feature

• The gas sensor incorporates an integrated barometric pressure sensor, making it impervious to atmospheric pressure fluctuations. It directly outputs readings for ambient atmospheric pressure (measuring range: 500~1200 mbar), oxygen partial pressure (measuring range: 0~300 mbar), and oxygen concentration (measuring range: 0~25%), facilitating easy user interpretation.
• Compared to electrochemical sensors, this optical oxygen sensor utilizes non-depleting oxygen-sensitive materials, offering a longer service life with a design lifespan of no less than 10 years.
• The fluorescence oxygen sensor operates at 4.5–5.5V with an average current of <7.5mA, featuring low power consumption, exceptional stability, and environmental friendliness. It contains no lead or other hazardous substances.
• Due to the high selectivity of oxygen-induced luminescence quenching, cross-sensitivity with other gases is minimal, making it virtually immune to interference from other gases.
