Handheld dust particle counter

SX - L301H SZ - 301 - h handheld dust particle counter

A, product introduction
SZ - 301 - h handheld particle counters using color LCD touch screen, the dust particle counter is used for measuring unit volume in the air in the clean environment of dust particle size and number, can be directly testing the cleanliness level for the clean environment in grade three hundred thousand to ten. This instrument adopts the semiconductor laser light source, LCD display, its small volume, light weight, high detection accuracy, operation simple and clear function, computer control, can be stored, printed sampling results, test the clean environment is very convenient. Widely used in electronic, optical, chemical, food, cosmetics, medicine, biological products, aerospace and other departments for public health.
