Introduction
The dust particle counter is an instrument used to measure the number and particle size distribution of dust particles per unit volume in a clean environment. It can be widely used in production enterprises and scientific research departments such as electronics industry, pharmaceutical workshop, semiconductor, optical or precision machining, plastics, painting, environmental protection, inspection institutes, etc.
The basic principle of the air particle counter is that the detection laser of the optical sensor is scattered by the dust particles and then received by the photosensitive element to generate a pulse signal. The pulse signal is output and amplified, and then digital signal processing is performed. By comparing with the standard particle signal, the comparison result is Expressed with different parameters.
Features
The dust particle counter is used to measure the number and particle size distribution of dust particles per unit volume in a clean environment, with a maximum sampling concentration of 35,000 particles/L.
The semiconductor laser light source has a service life of 10 years.
Microcomputer control, touch screen operation, automatic test and display test report.
6 channels of test particle size (0.3, 0.5, 1.0, 3.0, 5.0, 10μm), which can be detected at the same time.
The sampling period can be set by yourself, the minimum is 6S.
The instrument is portable, with its own battery, and the battery life is ≥5h.
The system can be self-cleaning, and the self-cleaning time is ≤10min.
The instrument has a temperature and humidity meter interface, and the monitoring report contains temperature and humidity data.
The data is automatically stored, and the built-in micro-printer can print the results directly.
U disk file data export, you can directly open EXCEL.
