Preface Welcome to PA-200N spray laser particle size analyzer produced by MRC Co., Ltd. PA-200N is a desktop laser spray particle size analyzer designed specifically for droplet size measurement of small spray equipment. It integrates many original patented technologies including lens protection devices, and can measure non-touched droplets and droplets scattered in the air.
As shown in the figure below, the laser particle size analysis software and the micro dog driver are installed. After installation, insert the encrypted dog into the computer, and then double-click the PA-200N icon of the desktop micro-nano software to use the software.

② . Then the nozzle is aligned with the test tube for spraying. At this time, the wave spectrum is attempted to appear in the spectrum test. After the graphics and concentration tests are stable, click on the button to start collecting and saving the data.
⑤ Click Print on the File menu, and the Print Settings dialog box will pop up. After setting up, click OK to print. If you don't need to print, you can also click the export function in the file option in the print preview. This software can export bmp, word, excel, txt and other files. Click Save on the File menu to save the current record list to a file.
particle. So the test conditions should be determined before the test, which will be comparable for the future testing of the same type of spray. ④ If the computer crashes, you can press Ctrl+Alt+Del at the same time, start the task manager to terminate the relevant programs or restart the computer.

2. After the replacement, turn on the power supply of the instrument, put pure water in the sample cuvette, double-click on the open software, then click on the connection to carry out background test, and then click on the energy spectrum test ten times after the background test. 3.

A---------relative error(%); -------Mean value of ten measurements of median diameter(µm); -----Standard median diameter of reference materials(µm)。 If A is less than 1%, it shows that the accuracy of the instrument measurement meets the requirements. (a) Verification of repeatability of volume median diameter measurements Under the same conditions, the instrument can continuously measure ten times with one sample of the same reference material, and the relative standard deviation of X50 is repeatability.
9. After click ok, go back to sample test interface,click “save data” will get new record, compare new accuracy error & repeatability error, If error <1%, calibration is done, drain out the certified reference materials, you can start to test your samples. Or repeat step 8.
