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.

Satisfactory product, however the temperature indicated does not correspond at all to reality. I have 26 degrees on the thermometer and the product indicates 24.5, which means that the ppm value is not correct because it is based on the measured temperature... Too bad. (Translated review)
