Bettersize laser particle size analyser uses particle size standard material to calibrate the accuracy. There are two types of particle size standard materials:
(1) Working standard sample provided by Bettersize, which is close to the actual sample, wide distribution, and cost effective.
(2) Internationally-standard particle size standard samples, such as Duke and Whitehouse. These samples are widely distributed, but more expensive.
Through the calibration of these standard samples, the accuracy of the Bettersize laser particle size analyser is fully guaranteed.
