Product Description

Brief introduction

Bettersize2000LD particle size analyzer is an intelligent dual-purpose particle size analyzer. Dry dispersing system adopts Venturi dispersing effect to ensure that powders are in complete dispersing state when pass test window by the way of shear, inertia, collision etc. The instrument has outstanding characteristics of high accuracy and reliability, good repeatability, easy operating, fast test speed, wide test range, etc. It is a new generation of particle size analyzer integrated dual lens technology and intelligent test technology, which is especially suited to the large enterprises, universities and colleges, research institutes and key laboratories.

Applications
Non-metallic powder: calcium carbonate heavy, calcium carbonate light, talcum powder, kaolin, graphite, wollastonite, brucite, barite, mica powder, bentonite, diatomite, clay, etc.
Metallic powder: aluminum powder, zinc powder, molybdenum powder, tungsten powder, magnesium powder, copper powder , rare metal powder, alloy powders etc.
Other powder: catalyst, cement, abrasive, medicine, agricultural pesticide, food, paint, dyes, fluorescent powder, river sediment, ceramic raw materials, various emulsion, etc.
Application fields: labs in material, chemical colleges and universities, large enterprises, key laboratory and research institution.

Good repeatability

Reasons of good repeatability:
Has stable and effective dispersion system.
Has stable and reliable laser device, detector, signal transmission system.
The automatic alignment system keeps the instrument in the best state all the time.
The sampling rate reaches 3500 times per second, mass data can effectively reduce the influence of a small amount of abnormal data on repeatability.
By using high precision lens group, the system has clear image and low distortion, which guarantees the faint and scattered light signal from all angles can be received 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 compsite factors.

Good accuracy

Reasons for good accuracy:
It adopts dual lens optical system which is designed by Bettersize. By adopting the quality composite lens, the precision of measurement improves greatly.
The number of photodetectors reaches 84, plus high performance software, which can carry out automatic test accurately no matter it is single peak, double-peak or multi-peak sample.
Complete sample preparation system includes circulation, ultrasonic dispersing, stirring, auto water supply, etc.
Use standard sample to verify and test result is identical with nominal value.

Compare with test results of overseas advanced laser particle size analyzer: good consistency.
