The LISST-100X instrument is a
multi-parameter system for in-situ observations of particle size
distribution and volume concentration. It also records the optical transmission, pressure and
temperature. The instrument is fully self-contained with battery and
data-logger. It can be used with supplied programs, or in specially
designed modes, e.g. event triggered based on storms (pressure
variance) or fronts (temperature front). Two size-ranges are available:
1.25-250 microns (Type B) and 2.5-500 microns (Type C). Standard memory
size is 16MB, suitable for storing approximately 115,000 size
distributions, with option to expand to 126MB, or 1,600,000 size
distributions. Special versions are available for deep-ocean,
high-concentration, or low-concentration environments. At the heart of
the instrument is a collimated laser diode and a specially constructed
annular ring detector (see Application Note L001).
Scattering
at 32 angles is the primary information that is recorded. This primary
measurement is mathematically inverted to get the size distribution,
and also scaled to obtain the volume scattering function (VSF), see
Application Note L002. The size distribution is presented as
concentration (micro-l/l) in each of 32 log-spaced size bins. Optical
transmission, water depth and temperature are recorded as supporting
measurements.
An auxiliary salinity sensor is available as an
option to obtain full CTD capability, see Application Note L003.
Designed for extended field application, the LISST-100 is a
self-contained battery-powered instrument that can be deployed on a
tripod, used in a profiling mode, towed, or moored. Many custom
versions of the instruments have been built, including for deep-sea
applications. Custom inquiries are welcome.
A large range of aceesories has been developed for the LISST-100X, please view our accessories page for a detailed listing.
