Product Details

Quick Details


Brief Introduction

   BT-1500 centrifugal sedimentation particle size analyzer is a particle size analyzer of high performance and extensive application which is developed by Bettersize. It adopts multiple sedimentation methods of gravitational settling, centrifugal settling, and combination of them, etc, centrifugal device and measuring device become an organic whole through ingenious design, and it has the features including wide test range, easy operation, quick and precise, real-time control of test process. It is an ideal particle size test instrument for the fields of production, scientific research and teaching, etc.

Other powders: cement, abrasive, medicine, agricultural chemical, food, coating, fluorescent powder, dye, catalyst, river sediment, ceramic raw materials, etc.



Good repeatability

Reasons for good repeatability:

laser, detector and signal transmission system are stable and reliable;

adopts high-precision and double speed synchronous motor which has stable and reliable rotate speed as well as low failure rate. It combines unique synchronous technology to realize continuous test simultaneously in the state of high speed centrifugation, which ensures the repeatability and accuracy of the instrument.







Test Value 1 (um)






Test Value 2 (um)






Test Value 3 (um)






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.

Our products have been sold to different places in 26 provinces, municipalities and autonomous regions in China, and are also exported to the worldwide market. We have occupied more than 20% of Chinese market. Now there are more than 900 Bettersize-made particle size analyzers operating smoothly around the world. With years of influence and good reputation in this sector, Bettersize has become a member enterprise of Chinese Society of Particuology.

Concerning Laser Particle Size Analyzer and Sedimentation Analyzer, typical products of us, we have two series divided into six types. Laser particle size analyzers include BT-9300H, BT-9300S, BT-2001LD, BT-2002; sedimentation particle size analyzers include BT-1500. Besides, we have BT-1600 Image Particle Analyzer and BT-1000 Powder Integrative Characteristic Tester. The principal performance of H and S meet requirement of most customers, in addition, both have high quality and low breakdown rate at moderate price.

We have our own R&D team in software development and design of IC, optics and mechanics. They possess specialized knowledge and years' of experience in particle size analyzer. We have developed advanced products yearly. Our quality control system is performed throughout the whole production, including processing of spare parts and accessories, purchase, examination, installation, test after connection, storage, packing and transportation. We have passed ISO9000 quality system certification.

On service, we have a concept of "Service, need of manufacturer actually". We make it better by: establishing customer files; specialized engineer perform installation, commissioning, training and after-sales service; full-time clerk communication with customers regularly by phone or Internet; full-time clerk in charge of the supply of spare parts and accessories.

We have made great success through years of efforts. Our customers includes scores of well-known universities, such as Tsinghua University, Harbin University of Industry, China Mining University, Shanghai Tong'ji University, Beijing Chemistry & Industry University, Hubei University and Zengzhou University; scores of well-known research institutes, such as China Science Institute including Shenyang Metal Research Institute, Shanghai Silicate Research Institute, Dynamics Research Institute and Dalian Chemistry & Physics Research Institute. Our particle size analyzer has actually become a standard particle size analyzer in domestic production and application of coal series kaolin and spherical aluminium powder.

Over these years, our products have been not only sold in different regions in China, but also exported to a large number of places all over the world, such as Japan, Korea, Thailand, Malaysia, Indonesia, Turkey, Syria, India, Pakistan, the USA, the UK and Canada, well received by all customers.

We have become a specialized and prestigious manufacturer of particle size analyzers.

Quality is vital to a company of dignity and honor.
