LPC-301 laser particle counter is used to measure the size and quantity of particles within air of unit volume in clean environment, it can directly measure clean environments from clean class 100,0000 to 10. This counter has used semiconductor laser power and big liquid crystal screen, so it is small, light, highly accurate, easing-operating and microprocessor-controlled. It may store and print the measure results, the printed result will show the clean class of that point and the measure of the clean environment is convenient. Besides, the computer shall be on long-distance control through proprietary software. The product is widely used in electronics, optics, chemistry, food, cosmetic, medical science, biological products, aviation, and so on.　 Pick up Parts characteristics：high accuracy thermal  printer inside, can be transferred to M3small, light ,easy-operating, convenient short self-purifying time with flowmeter itself
