  • Hanna Salinity Tester HI98319
    Bestseller #1
    Hanna Salinity Tester HI98319 (128)
      Waterproof and floats! Includes 4x of the Salinity Calibration Fluid Packets. Automatic Calibration – A 35.00 ppt solution is used for calibration and automatically recognized when in calibration mode. Displays results in parts per thousand (ppt), Practical Salinity Units (PSU), or specific gravity (S.G.) Salinity readings are performed by an amperometric graphite probe that resists oxidation, providing better repeatability in measurements. The use of graphite also reduces the polarization effect common with testers that use two stainless steel pins.
