    Abstract: The present invention relates to a dust measurement device and method which can increase the accuracy of dust measurement by deriving a mass concentration on the basis of a number concentration distribution according to particle sizes. The dust measurement device of the present invention comprises: a charging unit for charging a feed material with electrical charges; a first dust collecting unit including a first and a second dust collecting electrode which are spaced apart from each other, through which the material passes, and to which different voltages are applied; a second dust collecting unit for collecting the material which has passed through the first dust collecting unit; a current measurement unit for measuring current flowing through the second dust collecting unit; and a control unit for calculating a mass concentration of the material by using the value of the current measured by the current measurement unit and adjusting voltages applied to the charging unit and the first dust collecting unit on the basis of the mass concentration.
