Hand Held Salinity Refractometer

Hand Held Salinity Refractometer A refractometer measures refractive index to accurately determine the concentration of one substance when dissolved in another, for example; the 5% concentration of salt (Sodium Chloride) in water, which is required by most salt spray test standards The salinity refractometer offered by Ascott has been optimised to give a direct reading of percentage Sodium Chloride in the range 0 to 28%, with automatic temperature compensation. It is convenient to use, as a single drop of the salt solution to be measured is placed on the viewing window, using the pipette supplied, and its salinity read against a high contrast scale, graduated in % Sodium Chloride, to give an accurate reading.
