The Korallenwunder Refractometer Blueline Pro is a high quality device for determine the salt concentration in saltwater aquariums. The absolute salt concentration (°/°°, ppt) or specific density (kg/l) can be determined within seconds. When a beam of light enters the Blueline Proit is bent or “refracted” by the water in the test panel. This refraction is proportional to the salinity of the sample and can be directly read by viewing the internal scale. As salinity varies in inverse proportion to temperature Blueline Pro is fully temperature compensated. The strong plastic carrying case contains the Blueline Pro, a pipette for the water sample, a screw driver for calibration and full instructions.
