Refractometer C-scope
Measuring your aquariums Salinity has never been simplier with this Refractometer

The C-scope takes the guesswork out of measuring the salt in your tank.  Keeping a stable  salinity is vital for the well being of your fish and corals in a saltwater tank.  Rely on the precision of the c-scobe for precise measurements of the salt in your aquarium. 

The C-Scope features ATC automatic temperature calibration so you know for sure the readings you get are correct and in the correct parameters or specs that you need.

Compared to the old fashioned swing arm hydrometers that you are used to and much harder to use this refractometer is a breeze to use.

Be prepared for true salinity readings each and every time.

C-scope salinity Refractometer

The C-Scope Refractometer is designed for testing the concentrations of saltwater by providing a direct reading of thespecific gravity and concentration (Parts Per Thousand) of salt in water. The C-Scope provides a reliable refractive index and salinity readings of total dissolved solids of aqueous solutions. The refractive index is the ratio of 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 refraction is an indication of this speed change. Marine aquarists use this refractive index to determine how much salt is present in the aquarium water. Saltwater becomes less dense as the temperature rises.
