The most important equipment in mine work- portable gas detector

portable gas detector

Why is the portable gas detector necessary equipment for mine workers?

At least several thousand people die in mining accidents around the world each year. The frequency of mine accidents is particularly prominent in China and other developing countries. In 2003, China produced about 35 percent of the world’s coal. But accounted for about 80 percent of coal mine deaths.

Many factors can cause mine accidents. Including a toxic gas leak (hydrogen sulfide) or an explosion of natural gas (such as methane).  An explosion of coal dust, seismic activity, flooding, or mechanical and command failures. Toxic gases are the least detectable.

The important role of gas detection equipment in mine work

portable gas detector is necessary for every worker to wear when going down the well. In case of fire or poor air quality, the worker can remove the self-rescue device and open it, plug the mouth to save himself. Gas detection According to different field environments, the corresponding gas alarm and gas sensor should be selected.

In closed places, such as watercourses, agricultural sealed grain silos, railway tankers, tunnels, and other working places, a test is necessary. At this point, it is necessary to choose an alarm with a built-in multi-gas detection function. Because the distribution and type of gas in different parts of the confined space are very different.

Therefore, a complete closed space gas alarm should be non-contact, partial detection with multi-gas detection function, in order to detect the different spatial distribution of dangerous gases, and should be a portable instrument that does not affect the work of workers. Only in this way can the safety of workers entering a confined space be guaranteed.

A gas detector is a gas sensor that detects the composition and concentration of gas. It is mostly used in mines and other places with hidden safety hazards. Which can greatly reduce the occurrence of some possible mine accidents.

How can a Gas Detector help?

The composition of the gases in the mine represents a wide range of hazardous conditions. The toxic gases include carbon monoxide, carbon dioxide, sulfur dioxide, and oxygen deficiency. In some cases, methane may also reach explosive concentrations. Therefore, at present, in much underground gas detection equipment. Different types of gas sensors will be installed, such as oxygen sensors, carbon dioxide sensors, carbon monoxide sensors, and so on. Complex gas composition and concentration can be detected by changing different gas detection probes. Portable gas detection alarm device with built-in gas sensor detection components. It can automatically determine downhole gas, such as methane, carbon monoxide, hydrogen sulfide, etc. when the harmful gas content exceeds the standard, or insufficient oxygen, will automatically alarm, prompt staff evacuation or emergency rescue measures, minimize the occurrence of accidents.

A complete closed space gas alarm should be non-contact, partial detection with multi-gas detection function to detect the different spatial distribution of dangerous gases, and should be a portable instrument that does not affect the work of workers. Only in this way can we ensure the absolute safety of the workers entering the confined space.

In addition to the coal industry, petrochemical, metallurgical, military and other industrial fields must use explosion-proof equipment to ensure production safety. At present, the situation of production safety in Our country is still very serious. Explosion accidents happen from time to time, and the construction of production safety in various industrial fields is urgent. For coal mine enterprises, selecting reliable explosion-proof equipment is one of the effective means to restrain explosion accidents.

What can 4 in 1 gas detector do?

4 in 1 portable gas detector uses the latest digital integrated circuit technology and international gas-sensitive detection technology designed into a new intelligent gas detector. The use of large full-color LCD display real-time reading, probe selection of well-known brands in the industry probe, relying on several years of gas transmitter r & D experience, the use of mature and stable long-life probe program.

The detector adopts the natural diffusion method to detect gas, and the detection circuit designed by the digital chip of the international big factory can achieve very high sensitivity and excellent repeatability. The shell is made of industrial special high-strength composite plastic, with good strength and waterproof, dustproof, and explosion-proof functions.
