Product Details

Quick Details


Brief introduction 

   BT-2800 dynamic image particle size and shape analysis system adopts sheath technology, it has the functions of stirring, ultrasonic dispersing, etc. Just put the sample into the beaker for making suspension liquid in definite concentration, and particle size analysis could be carried out. When shoot the images, the computer recognizes and processes the particles quickly in the meantime, and the screen displays the images, particle size and particle shape data for each particle in real time. Analysis results includes L/D ratio and circularity for reflecting particle shape, particle size distribution, typical value and the largest particle value for reflecting particle size, specific interval contents, contents of less than or more than a definite particle size, specified equivalent particle size, etc. The system has the characteristics of imaging clearly, fast analysis speed, easy operating, accurate and reliable result, etc. It provides a high precision analysis method for study, production and application of abrasive, medicine, high performance metal powder materials, battery materials, rod-like and acicular materials.

Good repeatability

Reasons for good repeatability:

Laser, detector and signal transmission system are stable and reliable.

Stable and effective dispersing system.

High-speed sampling 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.

Company Profile

Dandong Bettersize Instruments Ltd. is a private high-tech enterprise specializing in the research, manufacture and service of particle size analyzers. We were established in 1995, and now staff more than 100 people, among whom engineers take up more than 50%. We have 1 comprehensive office and 4 departments, including R&D Dept., Production Dept., Sales Dept. and International Dept. In addition, we have marketing offices in Canton and Shanghai, with sales agencies in Korea and Taiwan area. 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. To achieve the long term goal of making competitive laser particle size analyzers and creating a famous global brand, Bettersize has established a complete and rigorous quality management system and a scientific and standardized manufacturing process, including designated and nominated purchasing, operating instructions according to working procedures, and 100% inspection for all components, assemblies, assembling processes, and finished products.
