Instrument Introduction

KR-W2000 is the latest product developed by our company. It has won the praise of our customers since its listing. The KR-W2000 wet method laser particle size analyzer uses the most advanced Mie scattering principle and concentrated light Fourier transform optical path. The high-density probe and the full-scale seamless connection test method ensure the accuracy and repeatability of the test results. The unique wet-process circulating dispersion system ensures no particle deposition during the particle testing process, and no waste liquid accumulation after testing the drainage, which ensures the second test accuracy and makes the test result more realistic and reliable. At the same time, the pipeline has no residue design. The accuracy of testing different samples is guaranteed. The superior optical path proofing system demonstrates the unique advantages of the KR-W2000.

Cope of Application

KR-W2000 is widely used in cement, ceramics, pharmaceuticals, emulsions, coatings, dyes, pigments, fillers, chemical products, catalysts, drilling mud, abrasives, lubricants, coal powder, mud, dust, cells, bacteria, food, additives, Measurement of particle size of pesticides, explosives, graphite, photographic materials, fuels, inks, metals and non-metals, powders, calcium carbonate, kaolin, coal water slurry, aluminum silver paste and other powdered materials.

Main Performance Characteristics 

Advanced optical path design: KR-W2000 adopts concentrated light Fourier transform test technology to ensure maximum range at the shortest focal length and improve the resolution of the instrument; unique high-density detection unit realizes forward, lateral and backscattered light At the same time, the W2000 has a strong ability to test small particles, allowing the KR-W2000 to have superior full-scale seamless testing capabilities.

Ultrasonic anti-dry burning: KR-W2000 truly realizes the ultrasonic anti-dry function. The ultrasonic power supply protects itself in the absence of sample cells, avoiding dry burning and damaging the ultrasonic system.

Ultrasonic power is adjustable: The KR-W2000 offers two options for ultrasonic power. You can choose between 0 to 50W for ultrasonic power and 0 to 70w for ultrasonic power.

Dust-proof and shock-proof design: The instrument is sealed as a whole, which greatly improves the service life of internal components. The unique anti-vibration mechanism can effectively avoid the interference of external vibration to the instrument, and make the result test more stable and reliable.

Strong anti-corrosion design (optional): It can be equipped with acid, alkali, oil (including all solvent oil) and organic solvent (such as acetone, phenol, n-hexane and other organic solvents) according to customer's actual needs.

Multi-laser optional: KR-W2000 adopts high stability, long life US MG imported He-Ne laser, excellent monochromaticity and stability make KR-W2000 have superior test repeatability (standard is domestic) You can also choose a high-power, long-life semiconductor laser (you choose a semiconductor laser, the price of the instrument will be slightly cheaper).

Automatic optical path calibration: Autofocus system, the instrument can automatically correct the optical path.

Unique micro-circulation system: The whole distributed circulation system is optimized. The dispersion medium can be cycled test with more than 150 ml, and the micro-circulation test is truly achieved. The optimized design ensures no waste residue after drainage, which ensures the accuracy of the next test result. Sex.

Ultra-wide range: The KR-W2000 has a range of 0.1μm to 2000μm.

Bubble-free design: The new design eliminates air bubbles from entering the test sample window during the entire test process, avoiding 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.

Intelligent test system: The powerful analysis software realizes the highly intelligent test of the instrument. The operations of water inlet, dispersion, circulation, concentration adjustment, test, drainage, cleaning, printing, storage, etc. are all completed under the computer under the computer. The test is completed in one minute.

Sample window quick change device: The newly designed sample window quick change device makes the sample window replacement more convenient and quick.

Other features:

Anti-corrosion design (optional): Can be equipped with acid, alkali and oil resistant (including all solvent oils) and organic solvents (all organic solvents such as acetone, phenol and n-hexane).

Analysis mode: including free distribution, R-R distribution and lognormal distribution, hierarchical classification

Meter mode, etc., to meet the different requirements of different industries for the statistical method of sample size.

Statistical methods: Volume distribution and quantity distribution to meet different statistical methods for particle size distribution in different industries.

Statistics Comparison: Statistical comparison analysis can be carried out for multiple test results, which can clearly compare the differences between different batches of samples, samples before and after processing, and test results at different times, which has a strong practical significance for the quality control of industrial raw materials.

From: User-defined data to be displayed, based on the particle size, according to the percentage

DIY display template: The ratio is determined by the particle size or the percentage according to the particle size interval to meet the characterization of particle size testing in different industries. Span, consistency, interval accumulation, etc.

Test Report: The test report can export various forms of documents such as Word, Excel, Picture (Bmp) and Text (Text), which can be used to view test reports and research results in scientific research articles in any occasion.

Multi-language interface: Chinese and English language interface support, and other language interfaces can be embedded according to user requirements.

Intelligent operation mode: Really automatic automatic unmanned operation, no one interferes with the factors, you only need to add the sample to be tested according to the prompt, the test results are more repeatable.
