Leaders in the aquatic field, Red Sea have an extensive range of products designed to enhance, develop and maintain your aquarium.
The Refractometer has been developed to the highest standard, and offers a more precise, absolute reading than similar products. It has been calibrated for seawater, at a temperature of 25C/77F, to give the most accurate reading. It uses an Automatic Temperature Compensation System for the most accurate measurement at the ambient temperature.
The unit uses refraction to measure the gravity and salinity of salt water, and enable you to study the results in great detail with the built in thermometer. The easy to read display has a high resolution too, so the results are clear to see.
The Refractometer comes complete with a sturdy plastic case to safely house the unit.
