The HI98319 Waterproof Salinity Tester is a simple, accurate, and economical way to determine salt concentration in saltwater aquariums.
HI98319 can measure salinity up to 70.00 g/L (ppt).
Results are displayed in g/L (ppt), practical salinity units (PSU) or specific gravity (SG) on a large dual-level LCD screen that also displays temperature. This waterproof tester uses a stainless graphite amperometric conductivity probe to determine the salt content of water.
