Detailed Description

The C-Scope refractometer is designed for testing the concentrations of saltwater by providing a direct reading of the speciific gravity and salinity in ppt.

It provides a reliable refractive index and salinity readings of total dissolved solids of aqueous solutions. The refractive index is the ratio of the the speed of light in a vacuum to the speed of light in the medium (saltwater) being measured. Light is slowed by passing through saltwater, so the index of the refraction is an indication of this speed change.

You simply add a few drops of your saltwater water over the prism and focus the eyepiece under direct lighting until you see a line that divides the scale from blue and white. This line indicates the specific gravity and the salinity. Clean off the prism and store. We recommend calibrating the refractometer before your next use. This tool will provide many years of TRUE readings, a must for all hobbyists!
