HI 76300 4-ring Platinum Conductivity Probe for use with EC 214 4-ring platinum probe for use with EC 214 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 stainless steel and ... Read More »
