Abstract

The present disclosure concerns a moisture concentration measurement device with an elongated measurement probe (12) configured to be moved in a body of pressed biomaterial (151) when moisture concentration measurements are performed. Before or after the probe (12) is moved, the control unit (118, 119, 120) initiates a moisture concentration measurement and reads an initial moisture concentration value from the moisture sensor. The control unit (118, 119, 120) then calculates a moisture concentration correction factor based on correction variables which include at least the estimated dynamic force and the biomaterial. The control unit (118, 119, 120) can calculate an adjusted moisture concentration value by adjusting the initial moisture concentration value with the moisture concentration correction factor,
