Hanna Instruments HI98319 Marine Salinity Tester measures electrical conductivity (EC) to determine the salinity of natural and artificial seawater. Within seconds, the salinity and temperature are measured, and then using the temperature reading, automatically compensated and displayed on the easy to read LCD screen. Ensuring the proper salinity in your reef tank allows your fish and corals more time to grow instead of having to adjust to constant salinity changes.
