RF006 Salinity and Specific Gravity Refractometer

Keep a salinity check close at hand when preparing seawater or brine. This optical refractometer uses a small sample on its prism to show a reading through the eyepiece, with an optional storage box.

✅ Check a sample without filling a container - A few drops on the prism are enough for the optical reading.

✅ Follow salt concentration during preparation - The salinity scale gives you a reference to record as you prepare a suitable solution.

✅ Choose storage for the instrument - The boxed option provides a place to keep the refractometer between checks.

Give Your Saltwater Mix a Measured Reference

When mixing water for a marine-aquarium routine, recording salinity gives you something to compare with the requirements of your system. Sample consistently and keep notes alongside the mixture rather than relying on appearance.

Calibrate with the appropriate reference and clean the prism between samples. Temperature compensation is specified for 10-30 degrees C, so keep to the stated conditions. Choose the with-box or without-box option; this model is sold for salinity checks, not general sugar measurement.
