Diffusion gas Detector

Diffusion gas detectors operate by allowing gas to naturally diffuse into the sensor, where gas concentration is measured using electrochemical or semiconductor principles. They are used for on-site monitoring of combustible or toxic gases and are commonly employed in industries such as chemical and petroleum for leak warnings and environmental safety inspections.
Selection
When selecting, consider the types of gases to be detected and the measurement range, pay attention to the sensor lifespan and response time, check the explosion-proof rating and protection standards, confirm the alarm methods and data logging functions, and adapt based on the environmental conditions such as humidity and temperature.
