Aqua Medic Refractometer with LED lighting
Handy salt meter with an LED in the valve for very easy reading. Always use the right-hand scale of the salt concentration in promille (‰ ppt)
A refractometer is an optical precision instrument for precisely determining the salt content in the seawater aquarium. The principle of the refractometer is based on the refractive index (light refractive index) and is directly related to the salt content in liquids.
The integrated LED lighting ensures a good reading even in poor light conditions.
