Industrial Safety: It is mainly used to measure the oxygen gas concentration in the environment, and is widely used in coal mines, steel, petrochemical and other industries, and can be applied to oxygen alarms and atmosphere analyzers.
Medical Field: It can be used in medical oxygen - making machines to monitor the oxygen concentration. It can also be installed on the oxygen - supply side of anesthesia ventilators to detect the inhaled oxygen concentration in real - time, ensuring the safety of patients during anesthesia procedures.
Air Quality Monitoring: It is applicable to air quality detection instruments, underground parking lots, commercial air - purification equipment, in - vehicle air - quality detection and other scenarios to monitor the oxygen content in the air.

Product Features:

False Alarm Immunity: It has the ability to avoid false alarms, ensuring the accuracy of measurement results.
Fast Response: The response time (T90) is less than 15 seconds, which can quickly respond to changes in oxygen concentration, and the enhanced response time in extreme applications can meet the needs of different working conditions.
Long - term Stability: It can reliably meet the stated life, with a long - term output drift of less than 2% signal/month, and typically less than 5% over the operating life. The expected operating life is at least 24 months in air, providing stable measurement performance for a long time.
Good Environmental Adaptability: It has superior environmental performance, with an operating temperature range of - 20 °C to + 50 °C, and can work continuously for up to 3 months across the relative humidity range of 5 - 95% non - condensing (at 0 °C to 20 °C). It can also adapt to the operating pressure range of atmospheric ± 20%.
High Measurement Accuracy: The measurement range is 1 - 25% vol. O2, and the output signal in air is 0.10 ± 0.02 mA, and zero current (offset) is less than 0.6% vol. O2, which can provide relatively accurate oxygen concentration measurement data.
Linear Output: In many cases, it can be considered linear, which is convenient for data processing and analysis.
