High Flow 50L Desktop Laser Dust Particle Counter
KQ-4050 high flow rate 50L desktop laser dust particle counter is the latest generation of our self-developed products. The product discards the LCD dot matrix screen commonly used in the market and takes the lead in adopting 7-inch IPS intelligent touch screen, which, together with the human-machine interaction UI, makes the operation more efficient and greatly improves the user experience. At the same time, the company is led by the post-doctoral team of CSU and cooperates with Nanjing University of Science and Technology in good faith to achieve accurate measurement of dust particles through precise photoelectric sensing technology. At present, the instrument has been widely used in clean scenes of pharmaceutical factories, electronic factories, hospital operating rooms, aerospace, precision processing, food industry, etc. It has become a common instrument for cleanliness testing of clean plants.
