Abstract: Provided are an apparatus for measuring an ionic mobility of a harmful material and a reference data obtaining method thereof. The method includes obtaining a measurement signal by detecting a charge of an ion between electrodes, obtaining a noise signal by insulating the electrodes from the ion, aligning the noise signal with the measurement signal, removing a part of the measurement signal aligned with the noise signal, and calculating reference data from a remaining part of the measurement signal.
