Hanna Instruments Salinity Tester

The Hanna Instruments Marine Salinity and Temperature Tester (HI98319) was designed to simplify testing your salt mix`s salinity and temperature in seconds, with reading results in parts per thousand (ppt), Practical Salinity Units (PSU), or specific gravity (S.G.). This waterproof tester uses a graphite amperometric conductivity probe, which is resistant to oxidation, improving the measurement repetition to determine the salt content in the water. The use of a graphite probe also reduces the polarization effect common with testers that use two stainless steel pins. Calibration is performed by pressing the dedicated calibration button. Once in calibration mode, the probe is placed in 35.00 ppt calibration standard. When the standard value is recognized and stability reached, the meter will automatically accept and store the value.  The Hanna Marine Salinity Tester displays the readings along with temperature on an easy to read large LCD screen.  Better Features for Better Testing With
