Brief introduction
BT-9300Z is an intelligent dual lens particle size analyzer which adopts integrated design, and all of operations can be completed automatically under control of the computer. It has particular functions of auto test, auto alignment, auto water supply, auto drainage, auto bubble removing, auto cleaning, etc. Adopts high performance semiconductor laser and life time is greater than 25000 hours; adopts anti-dry ultrasonic dispersing technology, so opening ultrasonic will not damage the instrument when circulating pool without water. The instrument has outstanding characteristics of accuracy and good reliability, good repeatability, convenient operating, fast test speed. It is a new generation of particle size analyzer which integrates technologies of laser, computer and photoelectron, and especially suits laboratories of enterprises, colleges and universities as well as research institutes to use.

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:
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 dual lens optical system invented by Bettersize, which improves the precision of the measurement greatly.
Photodetectors reach 86 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, 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.
