Marine Depot Aquarium Pro Refractometer - Regularly $64.99, Now $48.74
Specifically designed for aquarium use for measuring the salinity of Natural Sea Water. Almost all handheld saltwater refractometers available in the hobby are designed and calibrated for testing of brine solution, i.e. sodium chloride, and are not calibrated for the refractive index of NSW. This is a very important distinction. Other salinity refractometers used for marine aquariums are designed to test saltwater—nothing else! The Marine Depot Pro Refractometer is designed to measure the salinity of NSW and takes into account all the other elements that comprise salinity in the marine water sample.
