Methods and devices for measuring attributes of objects such as containers and container content without opening the containers are disclosed. Measurements of containers are obtained during conveyance via conveyor. For example, a sensor, such as a pressure sensing system, may measure pressure or contact between the container and the conveyor conveying the container. The measurements may be analyzed to determine characteristics of the container such as the weight, weight distribution and/or dimensions of the container. The conveyor may be configured to jostle the container such that an inertial property of the container and/or container content may be measured and analyzed. The measurements obtained may be used to ascertain a problem or characteristic of the container and/or container content without opening the container, such as damage, packing condition, number of units, presence of liquids, and the like. The method and device may be used through a materials handling facility.
