What is the difference between flammable and toxic gas monitors?
A 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 combustible gas enters the detector, it causes an oxidation reaction (flameless combustion) on the surface of the platinum wire, and the heat generated increases the temperature of the platinum wire, causing a change in its electrical resistivity.
Toxic gas detectors can be used to detect the concentration of toxic gases in the petroleum, chemical, and pharmaceutical industries in real time to ensure the safety of workers! The toxic gas detector is an interference free "intelligent" detector produced, which can detect the types of toxic gases and the breadth of its detection range, which is second to none in the industry.
Combustible gas detectors and toxic gas detectors are commonly used equipment in industrial settings, and many people are unaware of the difference between the two. The following article will explain to you:
1. Gas detection
The combustible gas detector mainly detects combustible gases, and uses methane as a standard to detect the concentration of combustible gases. According to the different combustible gases in the user's usage location, the concentration of the main gas can be used as the standard detection gas to set.
A toxic gas detector needs to know which specific gas or gases to detect. It can choose a separate toxic gas detection alarm or a composite toxic gas detector, depending on whether the toxic gas in the usage site needs to be detected as a single gas or multiple gases.
2. Gas sensor
The combustible gas detector uses catalytic combustion gas sensors, while the toxic gas detector uses electrochemical sensors, infrared sensors, PID sensors, etc. The unit concentration of the detected gas is different, and a series of formulas are needed for conversion.
