JDHS LD-5H Laser Dust Meter, Range 0.001~ 10 mg/m ³

Introduction

LD-5H/L laser dust meter is a light scattering fast dust meter with laser micro light source. The particle concentration can be directly read, the result can be obtained in 1 minute, or the sampling time can be set arbitrarily according to the user's needs, and the built-in filter sampling device can collect the particulate matter for the analysis of its composition while continuously monitoring the dust concentration, and find the mass concentration conversion coefficient K value. Built-in filter device to avoid the influence of dust on the instrument parts, prolong the service life of the instrument, with self-calibration system, with air curtain shielding and clean air self-cleaning function, to ensure that the optical system is not polluted, to achieve automatic zero adjustment of software, with two-way communication with the computer function, through the PC for data processing, printing curves and tables.

The instrument has a variety of functions such as continuous monitoring of particulate matter concentration, timed sampling and alarm of dust concentration exceeding the standard. Equipped with PM10, PM5, PM2.5, PM1.0 and TSP cutters for selection, the instrument adopts a powerful suction pump, making it more suitable for the detection of PM10 inhalable particulate matter concentration at the exhaust port of central air conditioning equipped with a long sampling tube, and the monitoring of inhalable dust PM2.5. LD-5H/L laser dust meter has obtained the People's Republic of CHINA manufacturing measuring instrument license and measuring instrument type approval certificate!

Explanation of the principle of laser scattering dust meter

The laser beam is irradiated on the dusty gas stream, so that the beam produces scattered light, and the higher the dust concentration, the greater the scattered light intensity, so that the dust concentration is measured. The light scattering method determines the concentration of inhalable particulate matter in the air in public places, which has the advantages of rapidity, sensitivity, good stability, small size, light weight, no noise, easy operation, safety and reliability. On the one hand, the method requires a small amount of sample due to its high sensitivity, and can eliminate or simplify sample handling steps, so that sampling and analysis times can be greatly reduced, and on the other hand, the method does not require sample storage, thus avoiding or reducing all possible error factors in the analytical method.
