The Milwaukee MA887 Digital Refractometer for Seawater Measurements is an optical instrument
that employs the measurement of the refractive index to determine the
salinity of natural and artificial seawater, ocean water or brackish
inter-mediates. The digital refractometer eliminates the uncertainty
associated with mechanical refractometers and is easily portable
for ship, shore or home use.
The Milwaukee MA887 Digital Refractometer is an optical
device that is simple and quick to use. Samples are measured after a
simple user calibration with distilled or deionized water. Within seconds,
the refractive index and temperature are measured and converted into one
of three popular measurement units; Practical Salinity Units (PSU),
Salinity in parts per thousand(ppt), or Specific Gravity (S.G. (20/20)).
All conversion algorithms are based upon respected scientific
publications using the physical properties of seawater (not
sodium chloride). The temperature (in °C or °F) is also displayed on the
large dual level display along with helpful message codes. |
