HOW TO MEASURE?

Take the hand holding the oblique prism of the refractometer tip at the end of the sample, while looking at the light, and while the lid is in the closed position, try to read the value in the measurement table as you visually position the binoculars. If the values ​​you have seen are not clear, you can adjust the sharpness by rotating the adjustment ring immediately above the binoculars and turning the measurement table to the right or left.

Making Zero Adjustment: First open the prism cover and drop 1-2 drops of distilled water on the inclined prism surface and close the cap slowly. So; a thin water layer will remain between the prism surface and the cover. The dark-light color difference image seen around the 0 (zero) line of the measurement chart, if not; For full alignment with the scale chart zero line, rotate the calibration screw with the aid of a screwdriver to ensure that the dark-light differential matches the measurement chart zero line completely.

WHERE IS IT USED?

Hand held salinity meter refractometers are designed for testing the concentration of salt water and brine. Its triple scale provides a direct reading of the specific gravity and concentration (Parts per Thousand ) of salt in water.

The Ordinary Salinity Values ​​of the Measured Saline Solutions:

If there is 36 grams of salt in 1 liter of water, the salinity of this solution is 36 ‰.
