Fast analysis of particle shape and size of powders and bulk solids!

With Dynamic Image analysis in an extra wide measuring range of 20 µm – 20 mm!

The FRITSCH ANALYSETTE 28 ImageSizer is the ideal Particle Sizer for fast analysis of particle shape and size of dry, free-flowing materials. Via the optical analysis of the particle shape and particle size, you can identify damaged particles, contaminates, agglomerates or oversized and undersized particles accurately and fast and view them completely uncomplicated in single images. The measuring time depending on the sample quantity, is under 5 minutes. And the result is available immediately. This makes the ANALYSETTE 28 ImageSizer the perfect measuring instrument for the easy quality control, as well as for research and for laboratory tasks – and it is the fast alternative to sieving.

Your advantages

- Extra wide measuring range of 20 μm – 20 mm, individually adjustable

- 3 telecentric lenses are available

- Up to 75 images per second

- Agglomerates are preserved

- Practical Clean Design of the measuring chamber

- Optimal number of particles due to automatic adjustment of the feeder

- Easy handling

Efficient dry measurement

For measurement, the sample material is filled into the funnel and conveyed to the falling chute via the automatically controlled feeder, which its U-shaped cross section ensures a 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.

Optimal number of particles due to automatic adjustment of the feeder

For exact reproducible measurements, the position of the feeder and the funnel height can be adjusted via a scale and stored as information in a SOP. The ideal feed rate, precisely adapted to the sample, can also be stored in the SOP. The particle concentration is determined and controlled by the software. Your advantage: always the optimal number of particles per image for a reliable and significant analysis.

Telecentric lenses for highest shape precision

Thanks to the bi-telecentric lenses, the ANALYSETTE 28 ImageSizer guarantees always the same reproduction scale of each individual particle wherever it is located in the measurement volume. Your advantage: a more accurate measurement by a higher magnification consistency.

Variable measuring time

The duration of the measurement can be varied depending on the desired number of images (up to 75 images/sec.) or on the number of measured particles.

State-of-the-art, simple and fast evaluation via FRITSCH Cloud and Gallery

The evaluation of the measuring results is uniquely simple with the ANALYSETTE 28 ImageSizer. The evaluation software ISS displays each recorded particle clearly as a data point in the immediately available FRITSCH Cloud as well as in the FRITSCH Gallery. You freely choose which statement is of interest to you: for example 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. Or display the particle size distribution as a cumulative curve, as a bar chart or in a table form.
