Torque wrench or other torque checking instrument, comprising color coded scales for imperial and metrical data

摘要

The tool (10) is assembled of a housing (12), accommodating the measuring mechanism, a handle (14, 16), and an element (20) for joining the tool (10) to the workpiece to be checked. A scale (24, 26), which can be analogue or digital comprises a imperial and a metrical area (28, 30), both easy to differentiate by their own color code. The data can be presented simultaneously, facilitating the comparison, or individually in the chosen mode. The tool (10) can be designed in the shape of a wrench or as a screwdriver.
