Milwaukee Digital Refractometer MA887 (1000-1114 sg.)

Refractometers are optical instruments that serve to determine the concentration of certain substances from the angle of refraction of light when passing through these liquids.

In this case, Milwaukee's array of refractometers measure salinity (NaCl) in the marine, brackish, or freshwater environment. This procedure is essential in controlling water conditions for aquariums and aquaculture.

The concentration can be measured in different units or scales:

• PSU, practical salinity units
• ppt, parts per thousand
• SG, specific weight

It includes automatic temperature compensation, between 10 and 40 ° C and temperature measurement in a range from 0 to 80 ° C. The resolution in the measurement parameters is 1PSU, 1ppt and 0.001SG. The light source of the refractometer is a yellow LED.

The precision is much higher than analog optical refractometers and is at +/- 2PSU, +/- 2ppt, +/- 0.002 specific gravity and +/- 0.3ºC. The reading is displayed on a practical LCD screen and the equipment contains a 9V alkaline battery that achieves 5000 readings.
