Every year at least thousands of people in the world die from mine disasters. The frequency of mining accidents is particularly prominent in developing countries such as China. In 2003, China produced about 35% of the world’s coal, but accounted for about 80% of the deaths from coal mine accidents.
There may be many reasons for the mine disaster, including toxic gas leakage (hydrogen sulfide) or natural gas explosion (such as methane), coal dust explosion, earthquake activity, flood or mechanical failure and command error，and toxic gases are the least noticeable.
The portable gas detection and alarm instrument has a built-in gas sensor detection element, which can automatically measure the gas in the well, such as methane, carbon monoxide, hydrogen sulfide, etc. When the harmful gas content exceeds the standard, or the oxygen is insufficient, it will automatically alarm to remind the staff to evacuate or emergency Rescue measures to minimize the occurrence of accidents.
Therefore, all types of explosion-proof equipment used in coal mines must comply with the national standard "GB3836-2000". If the explosion-proof equipment is not qualified, the internal explosion flame will be transmitted to the outside of the shell and directly with the combustible and explosive mixed gas underground Exposure may cause a mine fire and gas or coal dust explosion to cause a major malignant accident.
In confined places, such as waterways, agricultural closed grain silos, railway tank cars, tunnels and other working occasions, before people enter, they must be tested, and they must be tested outside the confined space.
A complete confined space gas alarm should be capable of non-contact, sub-site detection with multi-gas detection to detect dangerous gases distributed in different spaces, and should be a portable instrument that does not affect the work of workers. Only in this way can the absolute safety of the staff entering the confined space be guaranteed.
Gas detector is a gas sensor that detects gas composition and concentration. It is mostly used in some mines and other places where hidden safety hazards are hidden, which greatly reduces the occurrence of some possible mine disasters.
Explosion-proof equipment must be used in explosive environments. This is a requirement of my country's labor safety regulations. Except for the coal industry, explosion-proof equipment must be used in petrochemical, metallurgy, military and other industrial fields to ensure production safety. At present, the situation of work safety in my country is still very serious. Explosion accidents have occurred from time to time, and the construction work of work safety in various industrial fields cannot be delayed. For coal mine enterprises, choosing reliable explosion-proof equipment is one of the effective means to effectively contain explosion accidents.

A particle counter is an instrument that uses the scattering principle of light to count dust particles. Light scattering is related to particle size, particle refractive index, light wave wavelength and light absorption characteristics of particles. However, as far as the intensity of scattered light and particle size are concerned, there is a basic rule that the intensity of scattered light increases as the surface area of the particles increases. Thus a certain flow of dusty gas is passed through an intense light, and the particles emit scattered light, which is projected onto a photomultiplier tube through a concentrating lens to change the light pulse into an electrical pulse, and the number of particles can be obtained from the number of pulses. The particle diameter can be derived from the intensity of the scattered light as a function of the particle diameter. This is the basic principle of the light scattering particle counter.

These gases may also produce explosions in the counter. Measure these gases need to contact with the manufacturer for more information.
4. Do not sample compressed air without high-pressure decompression equipment (such as a high-pressure diffuser), as all particle counters are designed to operate at an atmospheric pressure.
5, Water, aqueous solutions or other liquids should not enter the sensor from the pipeline.
6, when connecting an external printer or connecting an external temperature and humidity sensor, the counter needs to be turned off first; when performing printing operations, the printer must have print paper, otherwise it will damage the print head.

In modern society, with the acceleration of industrialization and the existence of various dangerous environments, safety issues have become an important part of our lives that cannot be ignored. Especially in high-risk industries such as chemical, petroleum, coal mining, environmental protection, and fire protection, the leakage and accumulation of harmful gases often pose a fatal threat. Therefore, as an important safety device, portable gas detectors have gradually become personal guards for workers in all walks of life, silently guarding people's lives and safety.
I. Working principle of portable gas detectors
Portable gas detectors mainly detect specific gas components in the air through built-in sensors. These sensors can identify and measure the concentration of gases. When the gas concentration reaches the preset alarm threshold, the instrument will immediately issue an audible and visual alarm to remind the user to take emergency measures.
II. Main functions and features
1. Multiple gas detection: Portable gas detectors can usually detect multiple harmful gases, such as combustible gases (such as methane and hydrogen), toxic gases (such as carbon monoxide and hydrogen sulfide), and oxygen concentrations.
2. High-precision measurement: using advanced sensor technology to ensure the accuracy and reliability of measurement results.
3. Real-time alarm: when the gas concentration is detected to be excessive, the instrument will immediately sound and light alarms to remind users to evacuate quickly or take other safety measures.
4. Portable design: small and light, easy to carry, suitable for use in various complex environments.
5. Data recording and transmission: some high-end models also have data recording functions, which can store detection data and transmit it to computers or other devices via Bluetooth, USB, etc., for subsequent analysis and processing.
III. Application fields
Portable gas detectors are widely used in many industries such as petroleum, chemical industry, coal mining, metallurgy, fire protection, and environmental protection. In these industries, due to the presence of a large number of flammable, explosive, toxic and harmful gases, portable gas detectors have become an important tool to ensure the safety of workers.
IV. Precautions for use
1. Regular calibration: To ensure the accuracy of the measurement results, the portable gas detector should be calibrated regularly.
2. Correct wearing: When using, make sure that the instrument is worn in the right position so that harmful gases can be detected in time.
3. Pay attention to the use environment: avoid using it in harsh environments such as extreme temperature, humidity or electromagnetic interference to avoid affecting the performance of the instrument.
4. Replace the sensor in time: The service life of the sensor is limited and should be replaced in time according to the instructions to ensure the normal operation of the instrument.
As a personal guard to protect life and safety, portable gas detectors play a vital role in all walks of life. It can not only detect potential safety hazards in time, but also remind users to take emergency measures, thereby effectively avoiding accidents. Therefore, we should attach great importance to the use and maintenance of portable gas detectors to ensure that they can play the greatest role at critical moments. In the days to come, let us work together to create a safer and more harmonious social environment.
