Salinity Refractometer

Aquatic Salinity Refractometer for Marine Aquarium Testing

Monitor dissolved salt concentration in marine aquarium water with the Salinity Refractometer. Its easy-to-read scale, simple focus adjustment and automatic temperature compensation help produce clear, repeatable measurements. Only 2–3 drops of sample water are needed for each test.

The refractometer includes a carrying case and calibration screwdriver. To test a sample, place it on the prism assembly, close the daylight plate and wait approximately 30 seconds before reading the scale through the eyepiece. Use the tool as part of routine salinity checks for marine and reef aquarium setups.
