What is the difference between a combustible gas detector and a toxic gas detector
The combustible gas detector is a detector that responds to the concentration of a single or multiple combustible gases. There are two types of combustible gas detectors: catalytic type and infrared optical type. When the combustible gas enters the detector, it will cause an oxidation reaction (flameless combustion) on the surface of the platinum wire, and the heat generated will increase the temperature of the platinum wire, and the resistivity of the platinum wire will change.
Toxic gas detector can be used to detect the concentration of relevant toxic gases in petroleum, chemical and pharmaceutical fields in real time to ensure the safety of workers! Toxic gas detector is a non-interference "intelligent" detector, which is second to none in the industry in terms of the types of toxic gases that can be detected and the breadth of detection range.
Combustible gas detectors and toxic gas detectors are commonly used equipment in industrial places. Many people don't know the difference between the two. The next article will tell you:
1. Gas detection
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, it can be set according to the main gas as the standard detection gas concentration.
The toxic gas detector needs to know which one or more gases to detect. You can choose a single toxic gas detector or alarm, or you can choose a composite toxic gas detector. It depends on whether the toxic gas in the place of use needs to be detected. Yes, or a variety of gases need to be detected.
2. Gas sensor
Combustible gas detectors use catalytic combustion gas sensors, while toxic gas detectors use electrochemical sensors, infrared sensors, or PID sensors. The unit concentration of the detected gas is different, and a series of formulas are required for specific Conversion.
