Brief introduction
Bettersize2000 is an intelligent particle size analyzer that adopts dual lens technology, which has particular functions of auto test, auto alignment, auto water supply, auto drainage, auto bubble removing, auto cleaning etc. It adopts high performance imported semiconductor laser and life time is greater than 25000 hours. As adopting imported high precision battery of lenses, imaging clearly and low distortion, which ensures that weak scattered light signals and light signals from various angles can be detected completely. The instrument has outstanding characteristics of accuracy and good reliability, good repeatability, easy operating, fast test speed, etc. It is a new generation of particle size test instrument that integrates the technologies of laser, computer and photoelectron, and especially suits the laboratories of enterprises, colleges and universities and research institutes to use.
Principles
Laser diffraction measures particle size distributions by measuring the angular variation in intensity of light scattered as a laser beam passes through a dispersed particulate sample. Large particles scatter light at small angles relative to the laser beam and small particles scatter light at large angles, as illustrated below. The angular scattering intensity data is then analyzed to calculate the size of the particles responsible for creating the scattering pattern, using the Mie theory of light scattering. The particle size is reported as a volume equivalent sphere diameter.

Good repeatability
Laser, detector and signal transmission system are stable and reliable.
Stable and effective dispersing system.
Automatic alignment system keeps the instrument always in optimum condition.
Sampling rate can reach 3500 times/second, and mass data can effectively reduce the influence of repeatability caused by little abnormal data.
As adopting high precision battery of lenses imported from Japan, imaging clearly and low distortion, ensuring that weak scattered light signals and scattered light signals from various angles can be detected completely.
Kindly reminder:
Repeatability is primary index of particle size analyzer. It is worthless for particle size analyzer if repeatability is not good. Repeatability is related to the instrument, also, related to the operator, voltage, water quality and interference. It is a reflection of integrated factors.
Good accuracy
Adopts dual lens optical system invented by Bettersize and imported Japanese composite lens, which improves the precision of the measurement greatly.
Number of photodetectors reaches 90, plus high performance software, can carry out auto test accurately, no matter it is single peak, double-peak or multi-peak sample.
Complete sample preparation system included circulation, ultrasonic dispersing, stirring, auto water supply, auto drainage and auto cleaning.
Use standard sample to verify and result is identical with nominal value.
Compare with test results of overseas advanced laser particle size analyzer: good consistency.
