Hanna Instruments-76301D Conductivity Probe for use with Hanna Instruments-8633 and Hanna Instruments-8734
4-ring interchangeable probe with DIN connector, for use with Hanna Instruments-8633 and Hanna Instruments-8734 with 1 m (3.3') cable.
The potentiometric method eliminates polarisation 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 stainless steel and platinum rings are available. The platinum probes are ideal for high temperature applications, are easier to clean and provide more stable readings.
