Description of the Particle counter:
For the OC-400 Handheld three channels particle counter, the basic operating principle of the OC-400 wide size range particle analyzer is a laser scattering pulse signal of an aerosol particle output from an optical sensor which is processed and counted based on digital signal processing. The setting of measurement parameters, results display, and data storage are all controlled and realized by an internal microprocessor (MCU).
The OC-400 portable laser particle counter simultaneously measures three channel sizes that are configurable by the user. The data is recorded in the embedded flash memory and can be downloaded with supplied software through either a USB or RS232 interface.
OC-400 laser particle counter is designed in the USA and is in compliance with the international standards (JISB9925:1997 and ISO14644-1) and has CE certification. The 300 wide size range particle analyzer is very unique compared to other manufacturers in the market; it features high sensitivity, multiple functional capabilities, and is slim, lightweight and very user friendly.
Functions of the Particle counter:
Clean environment monitoring / Indoor air quality
Test/Check filter seal and efficiency / Trace contamination source
Analysis of particle size distribution
Applications of the Particle counter:
The model OC-400 Hand held wide size range particle analyzer can be used in measuring particles suspended in the air in clean environment applications such as microelectronics, fine mechanics, optics, pharmaceutical, medical device, food processing, aerospace as well indoor/outdoor air quality.
Features of the Particle counter:
Simultaneously measures 3 user configurable particle sizes
Counting modes with cumulative / differential / concentration / average / auto-repeat / timer
Up to 1500-data (450 sets) internal memory
Excess-count-limit warning
USB interface for data
