3X Oxygen Sensor AO-02 Gas Detector Compatible with AO2 AA428-210 AO2PTB-18.10_jsar1

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 and Fast Response – Measures oxygen levels from 0% to with an accuracy of 0.01%. Reacts in under 5 seconds (T90) and fully stabilizes in less than 40 seconds (T99.5). 3. Long Service Life – Designed for durability, it delivers reliable performance for up to two years under standard conditions, with a gradual signal loss of less than 10% per year. 4. Wide Operating Range – Works reliably from -20°C to and50°C, with humidity tolerance up to 99% (non-condensing) and pressure compatibility from 500 to 2000 mbar. 5. Easy Compatibility – This sensor is a direct replacement for models such as AO2 AA428-210 and AO2 PTB-18.10, commonly used in oxygen index meters and gas detectors. Product Details: The AO2 oxygen sensor is a consumable component used in oxygen measurement equipment. Once exposed to air, it begins operating through an electrochemical reaction. It provides a stable, linear output from 0% to O₂, with minimal zero offset (under 20µV) and low drift over time. The built-in temperature compensation ensures readings stay consistent in varying environments. Ideal for applications requiring precise, reliable oxygen monitoring.
