A refractometer is the most accurate way in which to measure salinity - the content of dissolved salt in your aquarium or pond water. The refractometer works on the principle of light refraction through liquids. When passing light through water, the refracted angle will be shown on the scale to determine the amount of dissolved marine or pond salt in that sample.

All refractometers incorporate automatic temperature compensation (ATC) and are suitable for applications where the temperature of samples vary.
The refractometers are manufactured from the highest quality materials and incorporate a rubber-insulated hand grip.
