The LISST-PORTABLE|XR is the world's only portable, battery powered laser diffraction based particle size analyzer. Designed for use in the field and the laboratory, it analyzes the sample in a wet state to obtain particle size distribution and particle volume concentration.
Pumped and recirculating mixing chamber that keeps large and heavy particles suspended.
7" touch panel display for measuring and displaying data with no need for a PC
Rechargeable battery allows for a full day of work without external power
Shock mounted optics that can withstand the rigors of field use
A built-in ultrasonic probe for complete sample dispersion
All data are immediately processed and stored in an ASCII file on the instrument for subsequent offloading and report generating.
Truly portable - completely self-contained with built-in data logger, processor, rechargeable battery, and 7” touch panel color display.
Touch panel allows for easy SOP programming, sample analysis and display of data without a PC.
Shock mounted optics block.
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.
Built-in ultrasonic probe for complete particle dispersion.
Based on the laser diffraction principle. Compliant with ISO-13320-1 standard.
