GWJ-16 Particle Counter is designed according to the principle of laser blockage method to size and count the unsolvable particles in injection, transfusion, macroviscosity solution, colored and organic sample particle examination as well as Particle size distribution measurement. Using high brightness laser source, 16-channels. Nearly 5000 kinds of particle size can be set.
It adopted such a high precision laser sensor, wide detection range, stable performance, not easy to plug, easy to do self-maintenance, can replace different specifications of sensors.
Its sampling system adopts an advanced precision piston pump. The sample volume to be set, the sample precision is high, not be affected by sample viscosity, high corrosion resistance and so on.

Features
1. The overall performance of this model meet and better than requirements of 2010 version of "Chinese Pharmacopoeia", It set testing standards of the pharmacopoeia detection, anesthesia equipment as well as infusion apparatus (GB8368-99 and GB8368-2005),may directly have a detection of particulate pollution directly in a variety of packs of injection, asepsis powder, drug packaging materials, anesthesia utensils, medical apparatus and so on.
2. Three calibration curves can be set in the instruments that stored the calibration parameters of different calibration methods and meet different industry requirements of particulate pollution detection; meet the latest international standard requirements that is ISO21501-new instrument calibration.
3. Wide detection range, 1～500μm, Detection function of particle size distribution
4. Nearly 5000 kinds of the particle size can be set by the user within 1.2 ~ 100um range on testing analysis so as to develop their own internal control standards. Especially for pharmaceutical research units and testing center , It has great advantages in multi-species detection.
5. With high resolution: >95%, Requirements better than the Chinese Pharmacopoeia .At the same time, It is the only according to the United States Phamacopoeia and the ISO21501 for resolution and indicators calibration of instruments.
6. Advanced precision syringe sampling system,Sampling accuracy is better than 1％, smallest sampling is 0.2ml,
7. Selects magnetic stirrer mode which is used universally in international instruments of the light blockage method. Compared with stirring from above, it can stir well and not easy to cause air bubble.
8. All anti-corrosion pipeline is designed in order to test the water matrix, each kind of oil matrix, organic solvents and weak acid that are some samples of corrosive.
9. Closed testing room, sampling head could go up and down automaticlly that take sampling easy.
10. Powerful capability for data storage and analysis, with analysis functions for data histogram, It can store 100 group test results.
11. Large-screen color LCD display, LCD and user-friendly menu prompts, touch screen operation with Chinese Pinyin input, It is extremely convenient that user manage files on the test results.
c12. RS232 serial port connected computer, the computer database software can store all the test data and possess function of data statistical analysis.
13. Voltage range: 100 ~ 264V, The instrument can overcome the power fluctuations, no need external manostat.
