Quantity:
BL-YQ-AO-02 is an electrochemical o2 sensor designed for use in various instruments related to oxygen detection, such as motor vehicle exhaust detection equipment, exhaust gas environmental protection detection equipment, oxygen index detection equipment, etc. Its use is limited to system monitoring. The data provided in this product is valid for 3 months from the date of gas sensors manufacture at 20°C, 50% RH and 1013 mBar. Please strictly follow the oxygen analyzer operating instructions and replace the oxygen sensor.
Advantages of electrochemical oxygen sensors include high sensitivity, short response times, and relatively low power consumption. This makes them widely used in medical equipment, industrial process control, environmental monitoring and other fields. However, regular calibration is required to ensure accuracy, and some specific models may be sensitive to humidity and temperature.
