CLJ-E dust particle counter Introduction
The Laser Dust Particle Counter is an instrument for measuring the number and particle size distribution of dust particles per unit volume in a clean environment. The basic principle is that the detection laser of the optical sensor is scattered by the dust particles and is generated by the photosensitive element receiving well. The pulse signal is output and amplified, and then digital signal processing is performed. The comparison result is compared with the standard particle signal. The parameters are indicated. The instrument's measurement parameter setting, measurement result display, button, timing, printing, time, date, data storage, etc. are all controlled and implemented by the built-in microcomputer (MCU). The instrument can simultaneously display the ambient temperature and humidity well monitoring report laser particle sensor. Working status. At present, there are more and more users of laser dust particle counters. Laser dust particle counters are widely used in medicine, electronics, precision machinery, color tube manufacturing, microbiology and other industries to achieve various clean levels of workbench, clean room, purification workshop. The purification effect and cleanliness level are monitored to ensure the quality of the product. The laser dust particle counter is an instrument used to measure the amount and particle size distribution of dust particles in the air, thus providing a basis for the assessment of air cleanliness.
