The invention relates to a mobile measuring device (10), in particular a hand-held measuring device, for non-destructive determination of a material measured value relating to a material property of a workpiece (42), in particular a measured material value in a workpiece (42), comprising a housing (12) in the at least one first Sensor device (32) and a second sensor device (60), a control device (28) for controlling the first and the second sensor device, an evaluation device (30) for evaluating at least one of the first and / or second sensor device supplied measurement signal and a device for power supply (22) of the measuring device are provided. It is proposed that the first sensor device (32) has at least one nuclear magnetic resonance sensor (32 ') and the second sensor device (60) at least one based on dielectric and / or resistive method sensor (60'), wherein by evaluating one of the Information about the material property of the workpiece (42), in particular a moisture present in the workpiece (42), which is used for optimized activation of the second sensor device (60) and / or optimized evaluation of the second Sensor device (60) supplied measuring signals is provided. Furthermore, the invention relates to a method for the non-destructive determination of a material measured value concerning a material property of a workpiece (42). |
