Brief introduction
BT-9300ST is an intelligent dual lens particle size analyzer which adopts integrated design, and all of the operations can be completed automatically under the control of the computer. It has particular functions included auto test, auto alignment, auto water supply, auto drainage, auto bubble removing, auto cleaning, etc. It adopts high performance imported 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 including accuracy and good reliability, good repeatability, easy operating, fast test speed, etc. It is a new generation of particle size analyzer that integrates the technologies of laser, computer and photoelectron, and especially suits the laboratories of enterprises, universities and research institutes to use.

Outstanding Features
1. Import semi-conductor laser runs for 25000 hours (4 times longer than common He-Ne laser) in wavelength 635nm and power 3mw.
2. Unique 84 photocells are highly sensitive and consistent so as to effectively capture even faintly scattered signal.
3. Two forms of sample feeding by circulation system and small cell assembly expand the applications. Small cell assembly suits costly, heavy metallic samples or samples not workable with water; Circulation system for metallic or non-metallic powders and many fields.
4. Process data by Mie scattering theory, inversion algorithm incorporates R-R, Free1 and Free2 distribution patterns in order to satisfy needs of various industries, fields and customers.
5. Passed calibration enables units to run with better accuracy and correlation.
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.
Good accuracy
Reasons for good accuracy:
Adopts dual lens optical system invented by Bettersize, which improves the precision of 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 samples.
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.
