摘要:
A trip hazard measurement gauge is, except for a measurement module and display, constructed primarily of aluminum. A cylindrical tube has an upper straight section and a lower straight section that are interconnected by a curved section. The upper straight section and the lower straight section form an obtuse angle. A cylindrical aluminum housing is connected to the tube via a conical connecter piece. A non-movable foot is rigidly connected to the cylindrical housing. A measurement module is installed within the cylindrical housing. A slidable rule, to which a movable foot is attached to a lower end thereof, extends from the measurement module. A return spring ensures that the movable foot returns to its lowermost position. After turning ON the display, selecting the measurement system and zeroing the gauge, it is ready to measure differences in elevation between adjacent sidewalk slabs.
