Characteristics of laser particle size analyzer:

● Good repeatability

This instrument adopts Furanhofer diffraction and Mie scattering theory, and the testing process is not affected by many factors such as temperature changes, medium viscosity, sample density, and surface state. As long as the sample to be tested is uniformly displayed in the laser beam, accurate test results can be obtained. Moreover, unlike the settling method, which does not require a settling process, multiple samples can be taken in one test (5-20 times can be set arbitrarily), effectively filtering out the influence caused by electrical noise and uneven sample distribution, and improving the repeatability of the instrument's testing.

● Wide testing range

Due to the use of large-sized photoelectric detection arrays (70 channels), lateral auxiliary photoelectric detection arrays (12 channels), and other corresponding technologies, the single lens testing range can reach 0.1-450 microns; And due to the fact that there is no need to replace the lens or adjust the optical system during the use of this instrument, the stability of the system is improved and the operation process is simplified.

● Adopting semiconductor laser generator

It has a series of advantages such as stable optical parameters, high efficiency, long lifespan, and resistance to vibration, overcoming the shortcomings of traditional gas lasers that require regular replacement due to natural gas leakage.

High degree of automation, simple operation

The GSL-101BI laser particle measuring instrument uses a microcomputer for real-time control, automatically completing functions such as data acquisition, analysis and processing, result saving, and printing. It is easy to operate and has a high degree of automation.

● Rapid testing

Due to the absence of settlement process, the testing speed is greatly improved, and under normal circumstances, a sample test can be completed within 1 minute. (Note: Excluding sample preparation time).

● Software

The testing program of this instrument is developed using MSVC/C++6.0 and runs on the Chinese Windows 95/98/ME/2000/NT/XP human-machine interface. The operation is intuitive, simple, and easy to understand. The data output is rich in content and can output English test reports. For color printers, color test reports can also be output.

● Adopting * mechanical stirring device

It has a series of advantages such as high stirring torque, fast speed, and uniform stirring.
