Overview
SJ-310D laser dust Particle Counter is used to measure the size and number of dust particles per unit volume of air in the air environment, and can directly detect the clean environment with a cleanliness level of 300,000 to tenth. The instrument adopts semiconductor laser Illuminant, Touchscreen display, high detection accuracy, large Flow rate, short Sampling time, can directly save data on U disk or control through computer, built-in thermal micro printer, test environment is convenient.
Features
1. Using Semiconductor Laser Illuminant, Life More Than 30,000 Hours
2. Touchscreen display, simple and clear operation
3. High detection accuracy, Flow rate, Sampling time is short
4. No need for computer data collection, can be directly saved in the U disk
5. Computer-controlled, storage and printing of sampling results
6. Built-in thermal micro printer
7. Built-in lithium-ion battery, replaceable, Typical Working time 6 hours
Principle
The instrument adopts the principle of light scattering. When the suspended particles in the air pass through the photosensitive area, the luminous flux is scattered in a certain proportion to its particle size. After photoelectric conversion, amplification and processing, the equivalent diameter and quantity of the collected particles are obtained.
Applications
Electronics, Optical inspection, Chemical, Food, Cosmetics, Biological products, Aerospace
