Salinity Refractometer - 0 to 100 PPT with ATC rockwool Better Starter: Use the starterThis Salinity Refractometer provides precise measurements of salt levels using specific gravity (SG) for Seawater and Salt Water Aquariums. Automatic Temperature Compensation (ATC) is perfect for field use as it compensates its readings according to temperature. The Salinity Tester can be used in oceanography and seawater studies for determining water quality. It provides reliable refractive index and salinity readings of total dissolved solids of
