The invention relates to a moisture meter for determining the moisture content of particulate material. The moisture meter comprises a frame part (1), a space (2), a measuring cup (3) disposed within said space (2) for receiving a sample of the particulate material which moisture is to be measured, and moisture measuring means. The moisture meter comprises a swiping means (9) for removing at least partly a part of a sample of particulate material which moisture is to be measured, which part of the sample of particulate material extends out of the inner space of the measuring cup (3) through the open end of the measuring cup (3). The swiping means (9) are movably attached to the frame part (1) for movement in a swiping path where a swiping member (10) of the swiping means (9) is configured to move essentially along the open end of the measuring cup (3).
