Portable Dust Laser Particle Counter 3 Channel CW-PPC300 with Printer 100V-240V

Description

Portable Dust Laser Particle Counter 3 Channel CW-PPC300 with Printer 100V-240V
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.
