What is the difference between combustible gas detector and toxic gas detector?
The combustible gas detector is a detector that responds to the concentration of single or multiple combustible gases. Combustible gas detector has two types: catalytic type and infrared optical type. When combustible gas enters the detector, it causes oxidation reaction (flameless combustion) on the surface of platinum wire, and the heat generated by it raises the temperature of platinum wire, and the resistivity of platinum wire changes.
Toxic gas detector can be used to detect the concentration of related toxic gases in petroleum, chemical and pharmaceutical fields in real time to ensure the safety of workers! The toxic gas detector is a non-interference "intelligent" detector, and the types of toxic gases that can be detected by this detector and the breadth of detection range are second to none in the industry.
Combustible gas detector and toxic gas detector are commonly used equipment in industrial places, and many people don't know the difference between them. The following article will tell you about it:
1, detection of gas
The combustible gas detector mainly detects combustible gas, and uses methane as the standard to detect the concentration of combustible gas. According to the different flammable gases in the user's place of use, it can be set according to its main gas as the standard detection gas concentration.
The toxic gas detector needs to know which one or more gases to detect specifically. You can choose a single toxic gas detection alarm or a combined toxic gas detector, depending on whether the toxic gas in the use place needs to be detected alone or multiple gases need to be detected.
2. Gas sensor
Combustible gas detector uses catalytic combustion gas sensor, while toxic gas detector uses electrochemical sensor, infrared sensor or PID sensor, etc., and the unit concentration content of detected gas is different, which requires a series of formulas for conversion.
