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

This fluorescent oxygen sensor is a solid-state optical O2 sensor for accurate oxygen concentration and partial pressure measurement. It supports 0–25% O2 detection, 0–300mbar oxygen partial pressure, and 500–1200mbar atmospheric pressure output with low drift, low power consumption, and long service life. Suitable for incubators, glove boxes, oxygen measurement equipment, oxygen generators, and controlled atmosphere monitoring.

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.
