The invention relates to a device (1) and a method for measuring moisture in die casting molds (24), the mold cavity (25) of which is connected to a venting device (28) via a vent line (31). The modular device (1) can be connected to the vent line (31) and comprises a sensor arrangement (S) by means of which the moisture of gases sucked out of the mold cavity (25) can be measured. The sensor arrangement (S) has a transmitter (7) emitting electromagnetic radiation and a receiver (14) which detects electromagnetic radiation. Based on the measured values determined during the evacuation process, it can be determined whether the quantity of a water-separating agent mixture which is injected into the mold cavity (25) before the actual casting process is to be changed. |
