Conductivity Calibration K 1.0 Set - Atlas Scientific RFID - Scanner PHPoC Expansion Board - PWMConductivity Calibration K 1. 0 Set Atlas Scientific An E. C. (electrical conductivity) probe measures the electrical conductivity of a solution. It is commonly used in hydroponics, aquaculture and freshwater systems to monitor the number of nutrients, salts or impurities in the water. Inside the conductivity probe, two electrodes are positioned opposite from each other, an AC voltage is applied to the electrodes causing cations to move to the
