Product Description

ST-P209A dual beams wet laser particle sizer is based on the patented dual beam laser particle size analysis technology independently developed by micro nano particles. By collecting scattering information over a large angle range, it improves the utilization of optical signals and ensures data stability and consistency in complex sample testing. The optimized optical structure and signal acquisition path effectively reduce optical interference, expand the available scattering angle range, and provide a reliable measurement basis for wide particle size distribution particle systems.

By combining the principle of laser scattering, optimized inversion algorithm, and strict calibration system, it achieves high repeatability and resolution particle size analysis, and can still obtain stable and statistically significant particle size distribution data in wide distribution, multi peak, and complex particle systems. By optimizing optics, algorithms, and calibration as a whole, reducing the impact of human and environmental factors, improving the comparability and traceability of experimental results, and ensuring consistent particle characterization in different scenarios.

Product Features

1 . Intelligent and fully automated operation, building a high consistency testing process
Support fully automatic intelligent operation mode to achieve true one click testing. Users only need to follow the prompts to add samples and start testing, and the system will automatically complete the entire process of water inlet, dispersion, circulation, measurement, cleaning, data analysis, and result output. Through standardized testing process design, the impact of human operation differences on test results is effectively reduced, and data consistency and credibility are improved.
2 . Automatic alignment of the optical path ensures long-term stable operation
The optical path automatic centering system is composed of a precision four item hybrid stepper motor, with a micro motion accuracy of 0.1 microns, ensuring that the instrument's optical path is always in the best state. This design not only eliminates manual centering operations, but also continuously guarantees the accuracy and stability of measurement results, enhancing the stability and consistency of long-term operation.
3 . Fully built-in integrated decentralized system ensures consistent sample status
Adopting a fully built-in dispersion system, mechanical stirring, ultrasonic dispersion, and circulation pipelines are organically integrated. Through integrated coordinated control and optimized flow path design, the sample transmission path is shortened, effectively suppressing the secondary settling of large particles during the testing process, and providing reliable sample conditions for stable and reproducible particle size measurement.
4. Dual beam testing
The use of dual laser and dual beam technology not only overcomes the optical interference of the sample cell, but also expands the testing angle and opens up a new field of wide distribution particle testing.
