Height gauges as the name indicates are used to measure the height of an object or workpiece with high precision and accuracy. These precision data can then be used for Quality control in manufacturing and production operations.
Height gauges consist of sliding carriage with a moving scribe which is mounted to a vertical axis beam
or column that contains a measuring scale.
The most standard mechanical height gages are Vernier height gages, dial height gages, and digital counter height gages.
Vernier height gages can make measurements up to 6 feet in height, making them ideal for larger works.
Dial height gauges are usually for smaller measurements of less than 12 inches, but this makes it great as a transportable tool that is easy to store.
Finally, digital counter height gages are easy to read, decrease measurement time, and allow for the setting of a floating zero point. Electrical height gages come in three main groups, each with an increasing level of accuracy, depending on your measurement needs.
The height can be used to measure the distance from a reference surface to a specific feature of a part to verify that it meets specifications and tolerances. It is also used to perform 2D measurements of part features and to verify center-to-center dimensions. Furthermore, it is also used to measure flatness, angles, and straightness/squareness or perpendicularity
