The height gauges are a measuring device used to determine the height of objects or to mark objects to be machining. The measuring tip with a carbide tip helps to mark workpieces. Height gauges, unlike tracing marker, have measuring heads (vernier, sprocket with graduated dial, or linear encoder with electronic display). Markers are only equipped with a stylus. Both devices are most often used on the cutting board, they have a heavy base with a precisely flat and smooth base.
