HI98319 is a digital salinity tester designed specifically for saltwater aquariums and displays results in parts per thousand (ppt), Practical Salinity Units (PSU), or specific gravity (S.G.). This waterproof tester uses an amperometric conductivity probe to determine the salt content in the water. This robust tester displays the readings along with temperature on a large LCD.
