ZHJ-L310A laser dust particle counter is used to measure the clean environment in unit volume of air in the dust particle size and number, Cleanliness level can be directly detected as 300000-100 clean environment. Instrument adopts the semiconductor laser light source, LCD screen display, import large flow sampling pump, import original binding big flow strainer, reasonable structure, high detection precision and function operation simple and clear, the microprocessor control, can store, Print the measurement data, test the clean environment is very convenient. In addition, it can store data through the computer specialized software download. Our products are widely used in electronic, optical, chemical, food, cosmetics, medicament hygiene, biological products, aerospace and other sectors.
