LD-3 laser dust analyzer

The principle of LD-3H/L laser dust analyzer is to use a laser beam to irradiate a dusty airflow, causing the beam to produce scattered light. The higher the dust concentration, the greater the intensity of the scattered light produced, thereby measuring the dust concentration.

1、 Instrument advantages
The light scattering method is used to determine the concentration of inhalable particulate matter in the air of public places, which has the advantages of speed, light weight, good stability, high sensitivity, small size, no noise, safety and reliability, and simple and convenient operation. On the one hand, this method has high sensitivity and requires less sample size, and can eliminate or simplify sample processing steps, thus greatly reducing sampling and analysis time; Another advantage is that using this method eliminates the need to store samples, thereby avoiding or reducing various possible error factors in the analysis method.

2、 Instrument features
1. Large screen LCD display
2. Fast, accurate measurement, and high detection sensitivity;
3. Designed a self calibration system with stable and reliable instrument performance;
4. Implemented software automatic zeroing;
