Brief introduction Laser particle size analyzer is based on measuring the particle size of the light scattering principle, see figure. With the advantages of large measurement range, fast measurement speed, easy operation, and so on, it is a kind of particle size analyzer which is suitable for wide application. The principle can be used for the determination of particle size distribution of powder, granule, emulsion droplet. Practical instruments are generally designed according to the specific use. Scattering occurs when the light is in the middle of the road. The scattering angle of large particles is small, and the scattering angle of small particles is large. The larger the scattering angle of the instrument can be received, the lower the lower limit of the instrument is. Features 1 With Inversely Fourier Transform optic structure, the detection of large angle scattered light is not limited by the lens diameter. 2 HE-NE laser source, stable output; Good optic characteristics(good monochromaticity and coherence, small divergence angle, stable); Fixed wavelength. 3 Detector array adopts the DAS patent 4 Bus control circuit, 1000times/second scan frequency, can process 0.06V weak signal. 5 Unique pinhole lock device. 6 Supercharge pump, 2800rpm, 10L/ min 7 German magnetic valve, 20 years life span. 8 Measurement window is made of high quality quartz glass, good wear-resisting property, low refraction index and good light transmission. 9 Enclosed optic unit. 10 Full range measurement without changing the lens. Technical Parameters 1. Test range: 0.2 ~ 500 microns 2. Sampling method: wet, circulation sampler and static sample pool 3. The repeatability error: < 3% 4. The test of time: 1 to 2 minutes 5. Independent detection unit number: 32 6. Light source types: helium neon laser, power: 2.0 mW, wavelength: 0.6328 microns 7. Working conditions: temperature: 5, humidity: < 85% 8. Output project: particle size distribution table, particle size distribution curve, mean grain size, the median diameter, specific surface area, etc
