The LISST-SL2 has a greatly simplified user interface compared to the original LISST-SL.
Uses laser diffraction; new: redesigned optics cover expanded grain size range, 1-500 microns (from 2-386 microns for LISST-SL)
Isokinetic; new: advanced pump control.
2-wire special communication protocol consistent with USGS B-reel use.
Topside Box (TCB) contains batteries, and transfers data to laptop computer using blue tooth.
Display on computer shows battery life remaining, and issues warning when low.
Real-time display: Current speed, temperature, concentration, grain size distribution, depth, mean sediment grain size.
New: software delivers point-integrated and depth-integrated sediment data.
Blue-tooth data link permits operation out of weather.
Switch between ft and ft/s or m and m/s for depth and velocity units.
Real-time data processing permits time-series or vertical profile format for all data.
Easier storage and maintenance after use.
