Optical Refractometer for Measuring Salinity in Marine Aquariums
The Grotech optical refractometer is a measuring instrument designed for the precise control of salt concentration in seawater. It allows for a direct reading of salinity, an essential parameter for maintaining stable conditions in marine aquariums.
Function and Measurement Principle
The refractometer operates by analyzing the refraction of light through a water sample. The integrated measurement scale allows for a direct reading of salt concentration, expressed in parts per thousand, without intermediate calculations.
The device is equipped with an automatic temperature compensation system, ensuring reliable measurements even in cases of moderate thermal variations.
Main Features
Type of measurement: salt concentration and salinity.
Reading: direct on optical scale.
Temperature compensation: automatic.
Use: marine aquarium.
Benefits for the Aquarium
Precise control of salinity is essential for the health of fish, corals, and marine invertebrates. The Grotech optical refractometer offers reliable and reproducible measurements, suitable for both reef aquariums and fish-only marine tanks.
Package Contents
An optical refractometer and a protective case are included.
Optical refractometer Grotech with automatic temperature compensation, for precise measurement of salinity in marine aquariums.
