Salinity Hydrometer for reading the salt level in Marine, Brackish Water and Turtle Tanks. These are a specific gravity meter that are made from a durable clear acrylic that are very easy to read and use. Unlike most others on the market that will only work for reading in Marine and Salt Water Aquariums our Hydrometers will read accurately all the way down to 1.000 (Distilled Water) which makes them great for use with brackish water tanks and for keeping an accurate level of salt in your turtle tank. We tried a number of brands and found this one to have the most accurate and stable low salinity level readings.
