Overview
BA-K212 model sensor is electrochemical electrical conductivity water quality detection sensor.It works by applying a constant voltage at both ends of the electrode of the sensor, so that the change of the resistance of the solution leads to a change of the current of the measuring electrode and the change is in accordance with Ohm’s law, the the resistivity value could be replaced by conductivity value, so as to achieve the measurement of the conductivity of the solution.
Key Features
