The BT-9300ST laser particle size analyzer is a compact, integrated laser particle instrument that uses dual lens technology. Its dual lens optical system allows for effective reception of forward and backward scattered light signals, expanding the measurement range and improving repeatability and accuracy. At the same time, its integrated structure makes the system more compact, with shorter pipelines, smaller size, lighter weight, and high cost-effectiveness.

As an intelligent laser particle analyzer, the BT-9300ST has special functions such as automatic testing, automatic alignment, automatic water inlet/outlet, automatic bubble elimination, and automatic cleaning. The intelligence not only simplifies operation but also reduces human factors' impact on test results. It meets international standards in terms of range capability,repeatability accuracy,and resolution. This instrument is particularly suitable for small to medium-sized laboratories in powder production and application enterprises,colleges,and research institutes.It serves as a reliable means of particle size monitoring for powder quality control ,production process control,powder application research,and new powder material research.

The BT-9300ST is a widely sold laser particle analyzer that has been exported in large quantities to over 20 countries and regions including the United States,Germany,South Korea,Brazil,Russia,Pakistan ,India,Vietnam,Malaysia,in addition to being sold domestically in 30 provinces,municipalities,and autonomous regions by the end of 2019,the sales volume of BT-9300ST both at home abroad had reached 1220 units.Its exquisite design,sophisticated manufacturing process,outstanding repeatability accuracy,and one-key operation have received high praise from domestic foreign users.

Salient features

●Optical path system: It adopts Baxter's advanced technology dual-lens optical path system, which is equipped with photodetectors in the front, side and rear directions, ensuring accurate reception of scattered light signals of all particles within the measurement range, ensuring accurate and reliable results.

●Automatic water inlet function: Built-in water suction pump and water level detector can absorb water into the automatic circulation and dispersion system, completely changing the design of relying on pressure or manual water inlet, simplifying operation, improving accuracy, and improving efficiency.

●Sample preparation system: Built-in automatic circulation, dispersion, water inlet, drainage, water level monitoring and other systems ensure that samples are fully dispersed and test results are stable and reliable.

●Automatic testing: Automatic centering, circulation, dispersion, testing, cleaning, saving, and printing functions completely change the situation in which the reliability of particle size test results depends entirely on the operator, making the results more objective and accurate.
