Non-contact type measuring apparatus able to detect a difference in signal intensity by transmitting a radio frequency (RF) signal having a predetermined frequency through one of two coil antennas and receiving an induced RF current signal transmitted via a medium through the other coil antennas and detect conductivity and a variation in characteristic of a non-conductor by comparing the signal intensity with a signal intensity comparison table for each frequency, which is stored in a controller by measuring a signal intensity for each frequency in advance, on the basis of the signal intensity for each frequency. The non-contact type measuring apparatus can accurately measure not only various elements using a characteristic in which conductivity is varied according to total dissolved solid, temperature, and an amount of a conductive medium and permittivity change characteristic of a non-conductor, but also conductivity and variation in characteristic of the non-conductor.
