Oxygen-Containing Gas Detector

Oxygen detectors measure the oxygen concentration in gases through electrochemical or optical sensors. The electrochemical type utilizes redox reactions to generate an electric current, while the optical type relies on the absorption of light at specific wavelengths by oxygen. They are used to monitor oxygen levels in confined spaces, industrial processes, and ambient air to ensure safety and process control.
Selection
When selecting an oxygen detector, considerations include measurement range, accuracy, response time, and environmental adaptability. Electrochemical sensors are suitable for routine detection, while optical sensors are better for high-temperature or corrosive environments. Confirm the explosion-proof rating, calibration methods, and maintenance requirements, and determine the model based on specific application scenarios and budget.
