◆ Dust particle counter is an instrument used to measure the number and size distribution of dust particles in a unit volume in a clean
environment. It can be widely used in the production enterprises and scientific research departments, such as drug inspection
institutes, blood centers, epidemic prevention stations, disease control centers, quality supervision institutes and other authoritative
institutions, electronic industry, pharmaceutical workshops, semiconductor, optical or precision machining, plastics, paint spraying,
hospitals, environmental protection, inspection institutes and so on.
◆ The basic principle of the air particle counter is that the detection laser of the optical sensor is received by the photosensitive element
after being scattered by the dust particles and generates a pulse signal. The pulse signal is output and amplified, and then the digital
signal processing is carried out. By comparing with the standard particle signal, the comparison results are expressed with different
parameters.
Feature Description:
◆ The dust particle counter is used to measure the number and size distribution of dust particles in a unit volume in a clean
environment, with a maximum sampling concentration of 35000 particles / L.
◆ Semiconductor laser light source, service life of 10 years.
◆ Microcomputer control, touch screen operation, automatic test and display test report.
◆ 6 channels (0.3, 0.5, 1.0, 3.0, 5.0, 10 μ m) of test particle size can be detected simultaneously.
◆ The sampling period can be set by itself, with a minimum of 6S.
◆ The instrument is portable, with battery, and the endurance time is ≥ 5h.
◆ The system can be self-cleaning, with self-cleaning time ≤ 10min.
◆ The instrument has a thermometer interface, and the monitoring report contains temperature and humidity data.
◆ Automatic data storage, built-in micro printer, results can be printed directly.
◆ U disk file data export can be directly opened in Excel.
