◆ Sj-310d laser dust particle counter is an upgraded product of sj-310d, which is used to measure the size and number of dust particles
in unit volume of air in the air environment. The instrument adopts semiconductor laser light source, color touch screen operation,
high detection accuracy, more simple function operation, computer control, can store and print sampling results, and the test
environment is very convenient. Widely used in electronic, optical, chemical, food, cosmetics, medicine and health, biological products,
aerospace and other sectors.
