Specialized measuring instrument for precision measurement of height dimensions of parts and machined components in manufacturing environments. Accurately measures object height from a vertical reference surface, used for quality inspection of machined parts, dimensional verification in assembly processes, and height adjustment of molds and fixtures. Available in digital and analog types with selectable measurement ranges typically 0-300mm, 0-600mm, 0-1000mm according to application. Features scriber attachment for marking operations and specializes in height direction dimensional measurement difficult with calipers or micrometers, valued in quality control departments and machining facilities.
