Applications

Advanced optical system

Inverting the Fourier optical system greatly reduces the stray light generated by the multiple reflections of the sample cell and the optical mirror. The large-angle scattered light is not limited by the aperture of the lens, which effectively improves the test resolution and ensures the accuracy of the test data. accuracy.
128-level multi-element detectors, each level of background light is independently compensated, and the gain is increased.
Imported semiconductor laser, dual light source test resolution is higher, main light source: wavelength 650nm, 30mw, lifespan> 70000h.
Auxiliary light source: wavelength 405nm, 20mw. The auxiliary light source enhances the resolution in the small particle size range.
The high-rigid optical structure supported by elastic, the optical path is stable, and the instrument is guaranteed to be in a stable state for a long time.The sample detection cell is glued with high-quality high-optical glass, and the metal material on both sides is reinforced (patented) to ensure the highest optical precision and mechanical strength, and a long service life.

Dry dispersion system

The dry test system consists of a main machine, auxiliary machines (built-in dust extraction system, dust storage waste tank, compressed air purification tank), silent air compressor and other parts, with automatic sampling, automatic dispersion, automatic testing and other functions.
Dry sampling system - dispersion powder spraying device, the sampling inlet is directly integrated with the spray gun, the transmission distance is short, and the samples are all quickly and continuously dispersed to the detection area automatically during the movement of the sample tank, without stratification and adhesion, ensuring the accuracy and stability of the test.
After the test is completed, the working chamber is automatically cleaned, and the waste is automatically collected into the auxiliary machine storage tank, which is not only recyclable for precious powder but also environmentally friendly and pollution-free. The test process is fully automatically completed under computer control, with a high degree of intelligence, and the results are automatically recorded and saved by the computer.

Wet Dispersion System

Wet method fully automatic circulation system - The wet method system consists of ultrasonic dispersion sample pool, mechanical agitator, circulation and other parts. It has functions such as automatic water absorption, automatic centering, automatic testing, automatic cleaning, water level overflow prevention, ultrasonic anti-dry burning prevention, etc. The built-in automatic water suction pump can automatically fill water without manual operation. A water level detector is installed above the sample pool. When the water level reaches the specified height, the electromagnetic valve closes to ensure the accuracy of each test medium.
When the sample is added, the large-diameter ultrasonic dispersion pool and the agitator work at the same time to ensure that the sample is quickly and evenly dispersed. The peristaltic pump circulation pipelines are all equal-section and equal-flow, without centrifugal negative pressure areas, easy to clean, no bubbles during transportation, and short-distance circulation, which effectively avoids sample agglomeration and ensures the accuracy and repeatability of the test.
