Measures Particle Size Distribution and Concentration; and Optical VSF

This model supersedes the LISST-100X.


The LISST-200X marks a major advance in technology of our workhorse LISST-100X submersible laser-diffraction instruments used for use in rivers, streams, ports, harbors, coasts and oceans. It also measures the small-angle optical volume scattering function (VSF).


Similar to LISST-100X, it too holds calibration for life.
