Continuous Oxygen Monitor

The fixed oxygen detector employs an electrochemical sensor to measure the oxygen concentration in the environment by generating a current signal through the reaction of oxygen with electrodes. It is used to monitor oxygen levels in confined spaces or industrial processes to ensure safe operation. Commonly found in settings such as chemical plants, warehouses, and other locations where oxygen concentration needs to be controlled.
Selection
When selecting a fixed oxygen detector, ensure the range and accuracy match the application scenario, check the sensor lifespan and calibration cycle, consider environmental tolerance such as explosion-proof rating, evaluate the compatibility of the output signal with existing systems, and confirm the installation method and maintenance convenience.
