What is the difference between combustible gas and toxic gas detectors
The combustible gas detector mainly detects combustible gases and uses methane as the standard to detect the concentration of combustible gases. According to the different combustible gases in the user's usage area, the gas concentration can be set according to the main gas as the standard for detection.
Combustible gas detection is generally used in situations such as petroleum and chemical industries where there are flammable hazardous gases, mainly targeting organic gases such as alkanes and inorganic gases such as methane and carbon monoxide. Combustible gases reaching a certain concentration, combined with sufficient oxygen concentration and ignition source, will produce an explosion. Explosions may be accompanied by large-scale fires and accidents, posing a threat to the safety of personnel and property. Therefore, in industries that produce volatile organic compounds during production and manufacturing, it is important to use specific combustible gas detection as a safety production standard, as most volatile organic compounds are flammable.
The toxic gas detector needs to know which specific gas or gases to detect. You can choose a separate toxic gas detection alarm device or a composite toxic gas detector, depending on whether the toxic gas in the usage area needs to be detected for a single gas or for multiple gases.
The application scope of toxic gas detection is relatively wider, targeting volatile organic compounds (VOCs) contained in production raw materials, or gases such as ammonia (NH3), carbon monoxide (CO), hydrogen sulfide (H2S), chlorine (CL2), hydrogen cyanide (HCN), nitric oxide (NO), sulfur dioxide (SO2) generated in the production process. These gases with concentrations exceeding specific standards can cause discomfort to the human body, lead to various diseases, and in severe cases, directly result in death. At the same time, the monitoring of these toxic and harmful gases is an issue that the country attaches great importance to in the prevention of occupational diseases.
The difference between combustible gas and toxic gas detectors is that combustible gas detectors use catalytic combustion gas sensors, while toxic gas detectors use electrochemical sensors, infrared sensors, or PID sensors. The unit concentration content of the detected gas varies.
