Salinity Refractometer - 0 to 28%

Measures salt content in sea water, pickling-brines and other applications. While the scale is calibrated for sodium chloride, it can also be used for calcium chloride, barium cobalt, magnesium, cesium, potassium, sodium chloride, cupric sulfate, potassium iodide, citric acid, acetic acid and (vinegar).Place a drop or two of a sample on the prism and read the results. Sper Scientific portable refractometers work in ambient light with no battery or other power source necessary. 0-28% Sodium Chloride Resolution 0.2, Accuracy ±0.2% 5 year warranty, RoHS, water resistant Range: 0 to 28% Sodium Chloride Resolution: 0.2% Accuracy: +/- 0.2% A refractometer measures the extent to which light is bent (refracted) through a liquid sample. They are commonly used to help identify or confirm the identity of a sample, assess the purity of a sample, or determine the concentration of a solute in a solution. They can be used in labs, on production lines, in the field or anywhere. Simply place a drop o
