This refractometer has a scale for measuring the salinity per-mill (ppt
or parts per thousand) and water density of seawater. By simple
operation the user can obtain a direct reading quickly of the salt
concentration and specific gravity of seawater. Sample types include:
seawater, artificial seawater, and salt waters.
Size and weight: 4 x 4 x 21cm, 200g
Salinity 0 - 100‰ (minimum scale 1‰)
Specific Gravity 1.000 - 1.070 (minimum scale 0.001)
The S/Mill-E is used to measure the salinity per mill (parts per
thousand) of seawater, artificial seawater, or salt waters. Perfect for
aquarium, educational, and industrial fields.
Includes: Protective storage case and owner's manual.
