HI 76301W 4-ring Interchangeable Conductivity Probe for use with HI 8033 4-ring interchangeable probe with DIN connector, for use with HI 8033 with 1 m (3.3′) cable The potentiometric method eliminates polarization and thus is the most accurate way to measure electrical conductivity in liquids. The probe can also measure in a wider conductivity range because it does not suffer from electrolysis. Models with ... Read More »
