Abstract
A fluid sensor for detecting refrigerant leakage from a refrigerant circuit includes a sensor main body having two electrodes spaced apart from each other. The fluid sensor is configured such that the fluid sensor is connectable to an impedance measurement device to measure impedance between the two electrodes.
