The principles of gas detectors can be divided into diffusion type and pump suction type. The so-called diffusion type refers to placing the probe in a hazardous area for detecting gas, spreading the gas to be measured into the probe from the space, and placing the alarm in the monitoring room for indication and alarm. The pump suction type is to pump the gas to be measured into the detection probe, and the suction pump is set together with the gas built-in detector. The detector is set at a dangerous location of the gas to be measured, so as to detect and execute the indication and alarm functions.

Single gas detector: using high-performance catalytic combustion sensors, it can be used to detect various combustible gases in industries such as petrochemicals, environmental accidents, natural gas, liquefied petroleum gas, coal gas, etc., including hydrocarbons, liquefied petroleum gas, natural gas, hydrogen, etc.
