This new digital salinity refractometer is a precision optical instrument used for measuring concentrations of substances in aqueous solutions. They work using the principle of lig ht refraction through liquids. When passing light through a liquid, the test result will be calculated by the computer and shown in the digital display. This MA887 actually measures the salinity of seawater, not sodium chloride levels, making it the ideal equipment for the enthusiast or expert aquarist in the marine aquarium hobby.Milwaukee refractometers are very simple to use: simply place one drop of your sample in the prism well, and read the results immediately!The new Milwaukee MA887 seawater digital refractometer encompasses 3 different types of user selected scales for the measurement of seawater providing for a much more precise evaluation. Each scale is temperature compensated. PSU - the newest type scale standard - letters stand for Practical Salinity Units and is fast become the universal standard for seawater measurement PPT - the old standard of Parts Per Thousand of saturated salt. This is the oldest of the 3 seawater measurements scales S.G. - the current standard of Specific Gravity hydrometers and refractometers. Key features include: Dual-level LCD Automatic temperature compensation (ATC) Easy setup and storage Battery operation with low power indicator (BEPS) Automatically turns off after 3 minutes of non-use Detailed instructions included with equipment All parts included for immediate use.
