Description: 1.Portable laser particle counter is the detection of air dust particles of clean room or clean room of the concentration, distribution and purification level detection (clean grade) of the special measuring instrument, it can be widely applied to various provinces and cities, the Blood Institute for drug control center, epidemic prevention station, CDC, quality supervision the authorities, the electronics industry, pharmaceutical workshop, semiconductor, optical or precision machining, plastic, paint, hospital, environmental protection, inspection and other production enterprises and scientific research departments, the ranking in the international level of similar products, is an ideal instrument for detecting user environment purification, clean room, clean room clean level.
2.The number of particles and the distribution of CW-PPC300 portable laser particle counter can accurately measure the local environment, the measurement of parameter setting, result display, buttons, timing, print, time, date, data storage by the built-in microcomputer (MCU) control and implementation, and can monitor the working state of the laser particle sensor. CW-PPC300 microcomputer control, can be directly printed test results. The utility model has the advantages of multiple functions, high measuring precision, high speed, convenient carrying and simple operation. The instrument can simultaneously measure the number of dust particles with different particle sizes, which is very convenient for the research, detection and evaluation of all kinds of clean environment.
3.The promulgation of the particle counter in accordance with international standards ISO14644-1 and GMP design and National Bureau of metrology JJG546-88 measurement standard calibration / English bilingual display with backlight, and on the three particle size file (user can arbitrarily set the measured particle size) were detected, the sampling time for up to 59 minutes and 59 seconds, sampling data as many as 1000 groups can be stored in the built-in flash memory, and can be easily downloaded via the USB interface. The instrument has the advantages of high precision, stable performance, high efficiency, easy operation, and achieves and exceeds all the performance indicators of the international similar products.
