Hanna Instruments 4-Ring Conductivity Probe

4-ring interchangeable probe with DIN connector, for use with HI 8633 and HI 8734 with 1 m (3.3ft) 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 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.
