Detailed Description

The Aqua Medic Refractometer is a precision optical instrument used to determine the salt concentration in saltwater aquaria. The exact value can be determined in seconds and can be read either as absolute salt concentration or as specific density.

Refractometers are non-electrical devices that work by measuring the refraction of light through an aquarium water sample on a glass plate. A screw driver for calibration is included.
