Adopting advanced central processing unit technology, it processes various collected data quickly and has strong anti-interference ability, greatly improving the detection accuracy of the instrument. At the same time, it can store 50 test records in chronological order. The instrument consists of a Chinese display screen, high-performance vacuum pump, dust concentration detection circuit, undervoltage protection display, safety power supply, etc. The instrument is equipped with a graded dust collector, which can collect the concentration of respiratory dust. The instrument can adopt automatic or manual sampling methods to adapt to different detection standards. This instrument adopts an Exibl (150 degrees) level safety explosion-proof structure, which is particularly suitable for use in coal mines and other workplaces containing explosive gases.

It is a light scattering rapid dust analyzer with laser as the light source. This instrument is ingeniously designed as an intrinsic safety explosion-proof dust detector with an alarm function for dust concentration exceeding the standard. It can measure five particle sizes including PM2.5/PM10, and can be portable for fixed-point monitoring or continuously monitored online.

Coal mine dust analyzerCharacteristics:

1. Using the principle of laser backscatter, it is not afraid of beam oscillation caused by mechanical vibration of the flue and uneven refractive index caused by uneven flue gas temperature.

2. Single end installation, no need for optical alignment.

3. It has on-site display function and can directly read the dust concentration on site.

4. After modulation, the laser beam greatly improves the anti-interference ability of the system.

5. The instrument design follows the concept of "tool free" on-site installation, minimizing the complexity of on-site installation to the greatest extent possible.

6. Adopting standard industrial standard current output, easy to connect.

7. The overall power consumption of the instrument is very low, about standard.

8. The general standard setting parameters can be applied when the thickness of the flue wall is less than the standard setting value, and the measurement area size can be customized under special requirements. Users can also make adjustments with the recognition and guidance of maintenance personnel.

The precautions during use are as follows:

(1) The instrument is prohibited from being used in environments with high dust concentration, environments containing water vapor, oil stains, and corrosive substances, as well as high-temperature environments.

(2) It should work in a state where there is no pressure or temperature difference between the sampling port and the working position of the instrument.

(3) The power plug socket must have reliable contact.

(4) Avoid vibration and impact when moving the instrument.

(5) Not suitable for occasions that require explosion protection.

Application location and environment:

Suitable for health quarantine testing, power plants, coal bunkers, grain warehouses, cement plants, and other industrial sites with high dust quality coefficients, safety testing in coal powder production workshops, and environmental testing in flour workshops;

Dust monitoring by labor departments of industrial and mining enterprises, workshops, fiberglass, filter cartridge dust removal, bag dust removal, electrostatic dust removal;

Environmental protection testing and pollution source investigation are suitable for environmental protection departments to conduct environmental acceptance monitoring of enterprises such as dust removal and cement, as well as municipal smoke monitoring; Rapid testing in scientific research, filter performance testing, and other aspects;

On site dust concentration measurement and exhaust dust concentration monitoring; Research on temporary online dust removal/granulation process;

Occupational health and safety testing factories require clean air in places where precision instruments, testing equipment, electronic components, food, pharmaceutical manufacturing processes, and various research institutions, meteorology, public health, industrial labor hygiene engineering, and air pollution research are needed.
