Introduction to the classification of portable gas detectors
According to the type of gas detected, it can be divided into toxic gas detectors and combustible gas detectors; According to the detection method, it can be divided into natural diffusion gas detectors and pump suction gas detectors; According to the number of detections, it can be divided into single gas detectors and multi in one gas detectors.
Combustible gas detector
A detector that responds to the concentration of a single or multiple combustible gases. The intelligent sensing transmitter used in the detector is a fully functional combustible gas sensing transmitter. The infrared combustible gas detector is an ideal choice for the following application environments: frequent exposure to catalytic toxic gases, frequent emissions of highly flammable gases, oxygen deficient environments, and environments where detection is difficult to achieve
Diffusion gas detector
The gas in the tested area flows slowly into the instrument for testing with the free flow of air, and needs to be placed on site. This method is affected by the detection environment, such as ambient temperature, wind speed, etc., and is not suitable for low-pressure gas sources. The advantage of a diffusion gas detector is that its cost is lower than that of a pump suction type.
Pump suction gas detector
The instrument is equipped with a gas sampling pump, which works by driving the power supply to extract and sample the gas in the test area, and then sending the sample gas into the instrument for detection. The characteristics of the pump suction gas detector are fast detection speed, remote measurement of dangerous areas, and maintenance of personnel safety. Suitable for situations where gas detectors cannot be placed on site and have special requirements for reaction speed, pressure difference, etc.
Single gas detector
Using high-performance catalytic combustion sensors, it can be used in industries such as petrochemicals, environmental accidents, natural gas, liquefied petroleum gas, and coal gas to detect various combustible gases, including hydrocarbons, liquefied petroleum gas, natural gas, hydrogen, and more.
Multi in one gas detector
The detection instrument can be configured with a single gas or multiple gas sensors, and can be equipped with a single, 2-in-1, 3-in-1, 4-in-1 or any of four toxic gas sensors or any single gas sensor for detection.
