Brief introduction

BT-2001 particle size analyzer is a high performance particle size distribution analyzer. Dry dispersing system adopts Venturi dispersing effect by measures of shear, inertia, collision, etc, to ensure that the powders are in complete dispersing state when pass through testing zone. Even for the sample which is difficult to disperse such as NdFeB powder, it can be dispersed completely and also accurate test result will be acquired. It adopts photodetector array of large size and high sensitivity made by large scale integrated circuit technique which is specially designed, and it has high resolution and good accuracy; adopts whole process Mie theory and data processing mode of multiple distribution models; adopts a series of advanced technologies and manufacturing techniques including high precision data transmission and processing circuit etc., to make the instrument has outstanding features including accuracy and reliability, fast test speed, good repeatability, easy operating, etc. It is a new generation of particle size test instrument which integrates laser technology, computer technology and photoelectron technology.

BT-2001 laser particle size analyzer is the high performance instrument which can be used under both dry and liquid system.

Good repeatability

Reasons for 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.

Kindly reminder:About Repeatability
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

Reasons for good accuracy:
Adopts semi-conductor laser of stable output, good monochromaticity and high efficiency which improves the precision of measurement greatly.
The number of photodetectors reach 84 pcs, 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 includes circulation, ultrasonic dispersing, stirring, auto water supply, etc.
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.
