Abstract: An apparatus for measuring step height or depth against another surface with a measuring arm mounted horizontally beside the scale which has a beveled end allowing precise readings regardless if the apparatus is being held perpendicular, the apparatus has exchangeable measuring arms with various reaching capabilities, and a handle mounted to the top of the scale allowing the apparatus to be operated with one hand. A preferred embodiment includes the apparatus at four to five inches in length whereas an operator is able to measure height and depth in difficult to reach places. In one embodiment, the measuring arm is stainless steel and has longer measuring arms, the handle is made of any resilient material which allows the apparatus to be carried securely in one hand, pocket and or stored easily due to its small size, the apparatus disassembles for cleaning.
