Ideal for

    The ANALYETTE 28 ImageSizer is the ideal Particle Sizer for all applications that require accurate and reproducible measuring results for both particle shape and size of powders and bulk solids.
    The optical process of Dynamic Image Analysis provides results for an extra wide measuring range of 20 μm – 20 mm, delivers multiple shape parameters and also offers a very easy and cost-effective alternative to sieving.
    Via the optical analysis of the particle shape and particle size, damaged particles, contaminates, agglomerates or oversized and undersized particles are identified accurately and fast, and can be viewed as single images. The measuring time depending on the sample quantity, is under 5 minutes. And the result is available immediately.
    Your advantage: Great flexibility in a wide range of measuring tasks – at a perfect price-performance ratio.

  • Typical areas of application

    Ideal for the analysis of: fertilisers, refractory products, glass and ceramics, carbon products, catalysts, plastics, foodstuffs, metals and ores, pharmaceutical products, carbon black and coal, salts, sand, abrasives and cements for fast, safe and uncomplicated quality control as well as in research and laboratories.
    And a fast alternative to sieving: If you conduct many and frequent sieve analyses, the ANALYSETTE 28 ImageSizer is the ideal, time-saving alternative completely without weighing, assembling of a sieve stack and time-consuming cleaning. And with substantially reduced follow-up costs, as there is no need to calibrate or purchase new sieves. Additionally, you receive besides the particle size distribution, also valuable information about the particle shape.

  • Automatic measurement with AutoCheck

    Optimal sample feeding via feeder
    For measurement, the sample material is filled into the funnel and conveyed to the falling chute via the automatically controlled feeder, which has a U-shaped cross section to ensure good material feed. There, the sample falls through the measuring chamber between the camera and LED strobe light into an easy to clean sample collecting vessel. The images recorded continuously during this process offer a variety of evaluation possibilities. And the sample remains undamaged and completely intact throughout the entire analysis process. Ask for different coatings of the feeder when using special sample materials.

    Optimal number of particles due to AutoCheck
    The AutoCheck function determines and controls the particle concentration. The ideal feed rate of the feeder can be set in the SOP – precisely adapted to the sample. Your advantage: always the optimum number of particles per image for a reliable and significant analysis.

    Fast, safe and uncomplicated measurement of particle shape and size
    Just add the sample, start the measurement, read the evaluation. With short measuring times under 5 minutes and reliable reproducibility due to pixel-precise evaluation for always consistent results. The duration of the measurement can be varied depending on the desired number of images or number of measured particles. Due to its special geometry, the measuring chamber is automatically kept clean so air flushing is not necessary. And nevertheless, if soiling should occur, it is fast and easy to clean.

  • Strong lenses

    5 megapixels for highest resolution
    The core of the ANALYSETTE 28 ImageSizer is one of the highest-performance industrial cameras. Its 5 megapixels provide highest resolution of even smallest particles and covers a large particle range. In one image large and small particles can be directly captured, displayed, edited and deleted. And a direct Ethernet connection to the computer ensures the fastest possible data transmission for evaluation of the results.

    Heavy-duty for all applications
    The telecentric lenses are also optimised for industrial utilization: With a simple, heavy-duty design, and hermetically sealed against dust and moisture, a precise opto-mechanical setting and high optical performance are ensured at any time.

    Always the right lens
    4 telecentric lenses with different measuring ranges are offered for the ANALYSETTE 28 ImageSizer. Choose according to your needs and order the appropriate lens for your measurement tasks. They can all be retrofitted at any time, and are easy to replace.

    Extra strong LED illumination
    For an automatically adjustable exposure time, that can be saved as an SOP, and perfect measurements, even with a smaller aperture. The flashing frequency is freely selectable, allowing optimal adaptation to each sample, and can easily be saved in the SOPs.

    Additional information about the lenses

  • Highest shape precision due to telecentric

    Thanks to the bi-telecentric lenses, the ANALYSETTE 28 ImageSizer guarantees completely distortion-free images of each individual particle in the same scale wherever it is located in the measurement volume. Your advantage: a higher magnification consistency and a more uniform CCD chip illumination. The specially selected aperture ensures the greatest possible depth of focus, without affecting the resolution due to the diffraction threshold.

  • FRITSCH Cloud - Easy evaluation

    The evaluation software ISS displays each recorded particle clearly as a data point in the immediately available FRITSCH Cloud. The really important information for you about the morphology will be shown by the position of the data point in the Cloud. You freely choose which statement is of interest to you: the Sphericity in regards to the Minimum Feret Diameter, the aspect ratio, applied on the porosity, or the convexity as a function of the particle Cross Section. Especially convenient: have several measurements displayed simultaneously in a chart and you will immediately see the differences between the relevant samples. A direct visual evaluation: brilliantly simple, uniquely flexible.

    Also the results of the particle size distribution are available either as a Cloud, as a cumulative curve, as a bar chart or in a table form. Or define a layout according to your sieve analysis. The displayed results are printed out as you set it up on the monitor.

  • Dynamic Image Analysis instead of a microscope

    With the principle of Dynamic Image Analysis, the ANALYSETTE 28 ImageSizer offers the same benefits as an analysis via microscope, but record up to 30 images per second, and therefore a considerably higher number of particles, due to the fully automatic process.

    Particle Analysis with the Camera

    Dynamic Image Analysis is a perfect method if not only the particle size of powders is to be determined, but if you also want to ascertain something about their shape.
