2X Oxygen Sensor AO-02 Gas Detector Compatible with AO2 AA428-210 AO2PTB-18.10

Feature Highlights: 1. Temperature-Compensated Output – The AO2 sensor’s reading can shift with temperature changes, but it has a built-in thermistor that automatically adjusts the signal. This keeps the output stable and accurate across a wide temperature range. 2. High Precision & Fast Response – Measures oxygen levels from 0% to 100% with an accuracy of 0.01%. It reacts quickly, reaching 90% of the reading in under 5 seconds and full stabilization in less than 40 seconds. 3. Durable & Long-Lasting – Designed for continuous use, with a service life of up to two years under normal conditions. Its output stays consistent, drifting less than 10% per year. 4. Wide Operating Range – Works reliably in temperatures from -20°C to +50°C, under varying humidity (0–99% non-condensing), and can handle different pressure conditions. 5. Easy Compatibility – This sensor is a direct replacement for models like AO2 AA428-210 and AO2 PTB-18.10, commonly used in oxygen index meters and gas detectors. Product Details: The AO2 oxygen sensor delivers precise, real-time oxygen concentration measurement. It integrates temperature compensation to maintain accuracy in changing environments. Ideal for analytical instruments, safety monitors, and laboratory equipment, it offers stable performance, minimal drift, and a long operational life. The sensor is a consumable component—exposure to air begins its service life, so it should be installed when ready for use.
