A device includes a cylinder having a cavity adapted to hold a concrete test cylinder, an accelerometer adapted to detect motion data, and a second sensor adapted to obtain measurements of a characteristic of the concrete during a predetermined time period. For example, the second sensor may be a temperature sensor. The device also includes a processor adapted to receive motion data from the accelerometer, determine that the device has moved during the predetermined time period, based on the motion data, and determine that the measurements obtained by the second sensor are invalid, based on the determination that the concrete test cylinder has been moved during the predetermined time period.
