Application of toxic and harmful gas detector

The use of poisonous and harmful gas detection and alarm instrument The harmful gas detection and alarm instrument is a special safety and health detector that is used to detect the content of flammable or toxic gases and vapors in the chemical workplace or in the air inside the equipment and to limit the alarm. In addition, the air-oxygen detector also belongs to this type of instrument. The detection of harmful gases in hazardous chemical sites mainly includes the following situations:

Leakage detection: Detection leaks on the site of hazardous gases or liquids (vapours) from the equipment pipeline, and leak detection of equipment pipelines.

Inspection and inspection: It is more important to detect residual harmful gases or liquids (vapors) after replacement of the equipments, especially for detection before the fire.

Emergency detection: When an abnormal situation occurs on the production site or an accident is handled, harmful gases or liquids (vapors) shall be tested for safety and hygiene.

Entry detection: When a worker enters a hazardous substance isolation operation room and enters a ditch, cable trench, or equipment operating in a hazardous area, harmful gas or liquid vapors must be detected.

Circuit inspection: When testing for safety and health, it is necessary to detect harmful gases or liquid vapors.

Dangerous chemicals should strengthen safety management, improve safety measures, and control hidden dangers of accidents. However, it is impossible to achieve absolute security and there will still be a situation of loss. Therefore, it is very necessary to detect and alert for hidden accidents and detect and alarm harmful gases or liquids (vapors) in hazardous chemical sites. It is of great importance to avoiding and controlling accidents.
