Large range laser dust analyzer

LD-5MLarge range laser dust analyzerIt can simultaneously monitor the concentration of dust particles of multiple sizes in the regional environment without the need to replace the cutter.

Features:

Exquisite design, suitable for flow monitoring of ambient air, with strong practicality. The internal components adopt a laser dust multi particle size monitoring system, which can simultaneously monitor the dust concentration of multiple particle sizes in the area environment without the need to replace the cutting head. The instrument achieves real-time monitoring of inhalable particulate matter through the principle of light scattering. Having a type approval certificate for measuring instruments. This instrument complies with the relevant provisions of the national metrological verification regulation "Dust Concentration Measuring Instrument" JJG 846-2015.

1. Working principle: laser dynamic scattering;

2. All use Chinese operation interface, easy to operate;

3. It can display measurement data of multiple particle sizes simultaneously without the need to replace the cutting head;

4. Real time display of dust mass concentration (mg/m3), with results available in one minute;

5. Designed a constant current controller to ensure a constant sampling flow rate and correct cutting curve;

6. A large capacity filter cartridge can ensure that the instrument can maintain a long-term working state in heavily polluted environments without the need to replace consumables;

7. Equipped with a special protective air curtain, it avoids dust pollution to the core component of the instrument - the optical system, ensuring high reliability of the instrument;

8. Data can be transmitted through various methods such as wired 485 transmission, 4G wireless transmission, LORAWAN wireless transmission, or network port transmission;

9. External filter cartridge design allows for continuous monitoring of particulate matter in the air while collecting dust samples for component analysis and determining the mass concentration conversion coefficient K value using filter membrane weighing method;

10. Optional zero point calibrator.
