The Milwaukee MA887 is a digital seawater refractometer with automatic temperature compensation. It shows the reading on a screen, so there is no scale line to judge through an eyepiece.

Who it suits

Worth considering over an analog refractometer if you measure salinity often or find the eyepiece scale hard to read.
