Fixed Oxygen Concentration Detector

The fixed oxygen concentration detector measures the oxygen content in the air through an electrochemical sensor. When oxygen diffuses into the sensor, it triggers an oxidation-reduction reaction, generating a current signal that is processed by the circuit to display the concentration value. It is used to monitor oxygen levels in confined spaces, industrial pipelines, and other areas to prevent safety accidents caused by oxygen-deficient or oxygen-enriched environments, ensuring production safety.
Selection
When selecting a fixed oxygen concentration detector, it is essential to consider whether the detection range covers 0–30% VOL, with an accuracy error of less than ±1%, and whether it includes audible and visual alarm functions. The explosion-proof and protection levels should be determined based on the installation environment, while the sensor lifespan is approximately 2 years. It is also necessary to review the product certification qualifications, ensure data stability and response speed, and choose between a split-type or integrated structure according to the on-site wiring conditions.
