Product Description:

The LISST-Portable|XR is the world’s first and only battery powered portable particle size analyzer. It can be used in the field, in the laboratory or on the factory floor.

The LISST-Portable|XR analyzes the sample in a wet state to obtain the particle size distribution and the particle volume concentration. The LISST-Portable|XR uses the same laser light scattering method (laser diffraction) as popular laboratory particle size analyzers.

It has all the features and performance of a laboratory instrument but in a self-contained, portable enclosure that allows you to make measurements where it’s needed, when it’s needed.

Features

  • Truly portable – completely self-contained with built-in data logger, processor, rechargeable battery, and 7” color touch screen display.
  • Particle Size Range 0.35 to 500 microns
  • Pumped and recirculating mixing chamber that keeps large and heavy particles suspended.
  • Shock mounted optics block that can withstand the rigors of field use.
  • A built-in ultrasonic probe for complete sample dispersion.
  • Touch panel allows for easy SOP programming, sample analysis and display of data without a PC.
  • Multiple Mie models as well as Fraunhofer model available for inversion, selectable from the touch panel.
  • All data-processing is performed on board and stored in ASCII format. No post-processing necessary.
  • Outputs: Total volume concentration, mean size, standard deviation, optical transmission, D5, D10, D16, D25, D50 (median grain size), D60, D75, D84, D90, D95, D60/D10 (Hazen uniformity coefficient), particle surface area, silt fraction, silt volume, size distribution, battery voltage, sample notes.
  • Based on the laser diffraction principle. Compliant with ISO-13320-1 standard.

Why do I need a portable particle size analyzer?

There are many applications where having a portable instrument is very helpful. Making measurements of samples from a small stream without sample handling issues or measuring drilling fluid on the drill site for faster results are two examples. However, having a portable instrument is also useful even if you only plan to use it in a lab environment. For example, you might have a need to measure particle size at multiple facilities but the cost of laboratory particle size analyzers is too high to justify one instrument at each location. Moving these instruments from place to place is not easy and takes too long. The LISST-Portable|XR can be easily moved from location to location with no setup. Open the lid, turn it on and you are ready to go. When you are done with it, just store it under the bench or in a cabinet until it is needed.   The costs in money and manpower for labeling, tracking, transporting, storing, and processing samples can be high. Making measurements right at the source can eliminate these costs while providing instant actionable data.
