LR-N6200 Dry and wet integrated intelligent automatic laser particle size analyzer


LR-N6200 Dry and wet integrated intelligent automatic laser particle size analyzer

LR-N6200 dopts the most advanced Mie scattering principle and convergent Fourier transform optical path. High-density probe and full range seamless test method ensure the accuracy and repeatability of test results. The unique wet circulation dispersing system ensures the particle to ensure that there is no particle deposition in the test process and no waste liquid accumulation after the test drainage, which ensures the accuracy of the second test and makes the test results more authentic and reliable. The dry method adopts the linear jet dispersion method, and the samples fly vertically backward after being dispersed by high-pressure gas, avoiding the secondary cluster of particles to be tested. Meanwhile, the pipeline design without residue is adopted to ensure the accuracy of testing different samples.LR-N6200 unique advantages are highlighted by its excellent optical path automatic proofreading system, dry and wet one-key switching system, dry computer remote control feeding system, etc.

The high density detection unit uses LR-N6200 to have super full range seamless testing capability.

Full range using a single lens to achieve 0.01 to 2,800m micron measurement.

 Fully sealed fiber semiconductor laser: the use of high stability, long life fully sealed imported fiber semiconductor laser, excellent stability so that it has a strong test repeatability, life is more than 30,000 hours.

Laser power monitoring and automatic adjustment: the exclusive use of constant power laser, real-time detection of laser power and automatic adjustment function, effectively avoid long-term use of laser power attenuation problems. At the same time, constant current, constant voltage and high filtering laser power supply are used to prolong the life of laser effectively, and the normal service hours are more than 30,000 hours.

Laser intelligent management system: the first to increase the laser intelligent management system, intelligent management system real-time monitoring of the working state of the instrument, once received the command of the work of the intelligent management system will instantly light the laser, high-performance laser will reach a stable working state in 3 seconds. After the sample test, the intelligent management system will automatically shut down the laser, and the laser basically does not decay. Theoretically, the laser can be replaced for life.

 Dry and wet one key switch: dry and wet switch will be automatically completed by the instrument, the whole process is completed within 10s.

 The main detector Z to automatic movement: after dry and wet switching due to the intervention of optical glass will lead to focal length changes, LR-N6200 will automatically adjust the main detector according to the dry and wet method, so that the main detector is always on the focal plane.

Large aperture lens: large aperture Fourier transform lens, more effectively realize the Fourier transform of optical signal, more accurate, more effective.

Anti-dry burning ultrasonic: LR-N6200 realizes water-free protection of sample pool to avoid damage to ultrasonic; The ultrasonic power is adjustable from 0 to 50 watts.

Dustproof and shockproof design: the whole instrument is sealed to greatly improve the service life of the internal components. The unique suspension structure can effectively avoid the interference of external vibration to the instrument, so that the test results are more stable and reliable.

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

 Imported fiber semiconductor laser: LR-N6200 uses high stability, long life imported high-power fiber output semiconductor laser, excellent monochrome and stability so that LR-N6200 has a super repeatability test.

 Laser intelligent management system: no preheating, on demand switch laser, sample detection after the laser will automatically shut down, this system can prolong the service life of the laser and protect the laser from external interference

 Automatic calibration of optical path X and Y direction: the instrument can adjust the optical path by itself if the optical path is slightly changed due to the change of sample window.

Unique micro circulation system: the whole dispersion circulation system has been optimized design, the dispersion medium is more than 150 ml can cycle test, really achieve the micro circulation test; All joints adopt the design of quick insertion and quick twist, all pipes can be replaced in a short time; The optimized design ensures no waste residue after drainage and the accuracy of the next test result.

Wide range: NKT6200-B range dry method reached 0.1μm ~ 2800μm, wet method 0.01μm ~ 2800μm.

 Free exhaust bubble design: the new design makes the whole test process will not have bubble into the test sample window, avoid bubble interference.

 Sample residue free design: the instrument pipeline and drainage structure are optimized design, the instrument pipeline, circulation pump without liquid residue, to avoid the impact on the next test data; The dry test was also designed to be residue free.

 Dry computer remote control feeding: LR-N6200 dry test test personnel can control the feeding speed through the computer, greatly reducing the labor intensity of the test personnel.

 New upgrade of feeding method: after the upgrade of dispersed good samples directly into the measurement area, can effectively solve the problem of inaccurate test results due to the second sample reunion; At present, we are the only one in China that adopts this method, and the imported instruments also adopt this method. Other manufacturers also need to disperse through a hose, which will lead to the reunion of samples again.

 Sample window: newly designed sample window quick change device, make sample window replacement more convenient and fast, easy to switch and automatic identification, sample pool automatic lock, easy to switch and maintenance of different dispersed systems
