​Magnum Media Salinity 10ATC is a professional brand of salinity measurement instrument. This refractometer is a portable, precision optical instrument. It is designed for the measurement of seawater or very low concentrated salt solutions. It measures on two scales – specific gravity and parts per thousand, making you get two readings at the same time in just one test. It is portable and needs no battery, it is easy to learn and use, easier and more accurate than a traditional hydrymeters, it is convenient for all people-children and adults, old and young, ideal for aquariums, marine monitoring, agricultural, gardening & educational purposes.
