China Laser Diffraction Particle Size Analyzer

BT-9300S laser particle size analyzer
BT-9300S is a laser particle size analyzer which adopts dual lens optical system, initially invented by Bettersize, with the functions of auto alignment, auto water supply, auto cleaning, auto water level measurement and auto dispersing. It adopts the structure that measuring and dispersing system are separated, easier for maintenance and use; 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 of accuracy and good reliability, good repeatability, easy operating, fast test speed, etc., and especially suits the 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 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 included circulation, ultrasonic dispersing, stirring, auto water supply, auto drainage and auto cleaning, circulation rotate speed which is continuously adjustable.
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.
