Hanna Marine Salinity Tester (HI98319)
HI98319 is a digital salinity tester designed specifically for saltwater aquariums that 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.
- Exposed Temperature Probe for Fast Response
- Measures salinity up to 70.00 ppt
- Waterproof and designed to float
Salinity measurements calculated from a conductivity measurement using known tables Choice of measurement units displayed in parts per thousand (ppt), Practical Salinity Units (PSU), or specific gravity (S.G.)
Automatic Temperature Compensation (ATC), displays temperature in ℃ or ℉
Amperometric graphite sensor reduces polarization effects and does not oxidize
Large LCD displays stability indicator, low-battery indicator, and calibration tags
Dedicated calibration button with automatic recognition of the 35.00 ppt calibration solution in calibration mode
Supplied complete with meter and calibration sachets in a durable plastic storage case.
