Downloadable instruction manual at the bottom of the page

The MA887 is an optical instrument that uses the measurement of the refractive index to determine the salinity of natural and artificial seawater, brackish intermediates, or seawater.

The digital refractometer eliminates the uncertainty associated with mechanical refractometers.

The MA887 refractometer is a simple and fast-to-use optical device. Samples are measured after a simple user calibration with distilled or deionized water.

In a few seconds, the refractive index and temperature are measured and converted into one of the three popular measurement units; Practical Salinity Units (PSU), salinity in parts per thousand (ppt), or density (SG (20/20)).

All conversion algorithms are based on respected scientific publications using the physical properties of seawater (not sodium chloride).

Temperature (in °C or °F) is also displayed on the large dual-level screen with helpful message codes.

Main features include:
• Automatic Temperature Compensation (ATC)
• Battery operation with low power indicator
• Automatically shuts off after 3 minutes of inactivity.
