Salinity or salt refractometer for seawater, brine and brackish water. The scale is parts per thousand: ‰. Indian ocean seawater for example is 36 or 37 ppt. Measuring Ranges: 0-100 ppt of NaCl and 1.000 to 1.070 Specific Gravity (0-10%); Divisions: 1 ppt / 0.001 Specific Gravity; Accuracy: ±1 ppt / 0.001 Specific Gravity (±0.10%)

Salinity, seawater, brine, brackishwater salt content measurement.


Use freswater to zero

Focus (the the eye end) so that you can read the scale. Add a dropof fresh water to the prism, closed the cover avoiding air bubbles. The fluid should spread across the entire surface. Wait about 30 seconds and view under light. Adjust the blue horizon to zero with a screwdriver or the adjustment nut, depending on the model design. The unit is now calibrated. Dry with a clean cloth or tissue. Add sample and close cover so that there are no air bubbles. Read the content indicated by the blue horizon line. Dry and clean and replace in storage container.
