Portable Particle Size Analyzer

LISST-Portable|XR - Sequoia Scientific, Inc.

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.
