Hanna Instruments HI98319 Marine Salinity Waterproof Tester
A digital salinity tester called HI98319 that is intended for saltwater aquariums shows results in parts per thousand (ppt), practical salinity units (PSU), or specific gravity (S.G.). The salt content of the water is measured using an amperometric conductivity probe using this waterproof tester.
- Exposed Temperature Probe for Fast Response
- Measures salinity up to 70.00 ppt
- Waterproof and designed to float
Description
Features
