Winner802 laser nanometer particle size analyzer for ceramic powder test

 

  Winner802 is our company's latest laser particle size analyzer which based on the dynamic light scattering principle, and also 1st one which use digital correlator in China. Based on Brownian movement principle, smaller particle, faster speed, bigger particle, more slowly. It adopt great performance of  HAMAMATSU photomultiplier and self-developed high speed digital correlator as core parts, Get diffusion coefficient by test scattering light change in some angle, and calculate particle diameter and distribution according to stokes-Einstein equation. So the machine is with characters of fast calculation, high resolution ration, good accuracy and repeatability.

 

 

 

Main Features:

 

1) Advanced test principle

  Dynamic scattering light technology, It could keep nanometer particle original state, guarantee    

  realness and effectiveness of test result.

 

2) High sensitivity and Noise-signal ratio

  Detector is composed of HAMAMATSU photomultiplier, so ensure good accuracy.

 

3) High speed data collection

  Self-developed patent product-CR256 digital correlation, It could finish dynamic scattering light  

  intensity collection and autocorrelative function calculation, effectively reflect dynamic  

  scattering light information of different sizes of particles.

 

4) High stable light system

  Photon correlation spectrum detect system adopt optical-fibre technology, smaller size and high    

  anti-interference and reliability.

 

5) High precision constant temperature control system

  Semiconductor temperature control technology, precision control within ±0.2℃,make samples   

  be in a constant state throughout the testing process, prevent testing error because temperature  

  change will change liquid viscosity and Brownian movement speed.
