Oxygen Gas Concentration Detector

The oxygen gas concentration detector measures oxygen content through an electrochemical sensor. When oxygen reacts with the sensor, it generates a current signal, which is then converted by the circuit into a concentration reading. It is used to monitor oxygen levels in confined spaces or industrial environments, ensuring personnel safety and preventing risks of hypoxia or oxygen enrichment. It is commonly found in chemical plants, mines, laboratories, and other similar locations.
Selection
When selecting an oxygen gas concentration detector, consider whether the measurement range covers environmental requirements, such as 0-30% by volume. The sensor lifespan and calibration cycle affect usage costs. The device must have an IP protection rating to adapt to humid or dusty environments. Check whether the response time and alarm functions meet safety requirements. Choose between portable or fixed types based on the application scenario. Ensure compliance with relevant industry standards.
