ISO13320 wet automatic dispersion particle size analyzer
Mie scattering theory with full-scale, fully taking into account the refractive index of the optical properties of the particles and the dispersion medium measured particle size distribution data, depending on the size of the particles in each angle scattered light intensity changes on the anti-particle group performances.
Particle sizing calculations are generally divided into unconstrained fitting inversion and the constrained fitting inversion. Constrained fitting inversion before the calculation assumes that match a certain distribution of particle group, according to the law of inverse particle size distribution. This type of operation is relatively simple, but because of prior assumptions inevitably exists between the reality of bias, thereby testing the constrained fitting data do not reflect the actual particle size distribution of the particles.
Unconstrained fitting inversion test before the particle does not make any assumptions, by light intensity directly and accurately calculate the size distribution of particles. Such assumptions are reasonable detector and particle classification, to make high demands on the device itself. SKZ1062 Wet-laser particle size Analyzer, using optimum of non-uniform cross-dimensional fan-shaped array of detector arrays and reasonable size grading, making it possible to accurately measure particle size distribution.

The unique anti-vibration structure can effectively avoid the interference of external vibration to the instrument, and make the test result more stable and reliable.
Automatic alignment: The exclusive use of the combination of mechanical center and optical center, the optical path automatically adjusts the positioning more accurately, reaching the micron level; at the same time, the optical path adjustment speed is faster and faster and can be adjusted in 15 seconds. The self-developed automatic alignment system consists of stepper motor, precision guide rail, precision controller and software system. The minimum step distance is 0.2 microns, ensuring that the focus of the laser beam always passes through the center point of the detector, improving the accuracy of the test results and testing. Repeatability.
Free bubble design: The new design makes no bubbles enter the test sample window and avoids air bubble interference.
Sample no residue design: The instrument pipeline and drainage structure have been optimized, and there is no residual liquid in the instrument pipeline and circulation pump to avoid the impact on the next test data.
