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.

Features

• 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.
