One example is a shock gauge system for measuring an external blast to a hull. The shock gauge system includes at least one accelerometer to produce acceleration data in response to the external blast, a mass with an accelerometer affixed to it, a crush block, a linear displacement potentiometer (LDP), a camera, and a processor logic. The LDP device generates displacement data of a mass being pushed into the crush block when reacting to the external blast. The camera captures images of movement of the mass. The processor logic verifies if the acceleration data is valid by correlating the acceleration data to the displacement data, the images, and/or an amount of displacement into the crush block by the mass. When the acceleration data is valid, the acceleration data may be used to create a more blast resistant hull.
