Oxygen Concentration Detecting Probe

The oxygen concentration detector measures the oxygen molecule content in gases through electrochemical or optical sensors, converting chemical signals into electrical signals to display numerical values. It is used to monitor oxygen levels in confined spaces and industrial production environments, ensuring operational safety and preventing risks of hypoxia or hyperoxia. It is commonly found in laboratories, mines, medical oxygen supply systems, and other locations.
Selection
When selecting, consider whether the detection range covers 0–30% VOL and the accuracy error is less than 0.5%. Confirm the sensor lifespan and calibration cycle; electrochemical sensors typically last 2–3 years. Check the explosion-proof rating and IP protection standards, with ATEX certification required for hazardous environments. Ensure the response time is below 15 seconds and that the device is equipped with audible and visual alarm functions. For portable devices, prioritize battery life; for fixed installations, focus on signal output interfaces.
