Leakage Gas Detector

Leakage gas detectors identify changes in the concentration of specific gases in the air through sensors. When gas molecules come into contact with the sensor, they generate electrical signals or optical reactions. These detectors are used in places such as chemical plants and laboratories to monitor gas leakage from pipelines and valves in real-time, preventing the accumulation of flammable or toxic gases.
Selection
When selecting, consider the compatibility between the gas types to be detected and the sensors, ensure the measurement range covers potential leak concentrations, check if the explosion-proof rating suits the environment, pay attention to response time and calibration cycles, evaluate the suitability of the equipment's protection level for the usage scenario, and compare the continuous operation time of different power supply methods.
