Height Gages Information

Show all Height Gages Manufacturers

Height gages or gaging systems are used for measuring the height of components or product features.  These include vernier height gages, micrometer height gages, surface gages, or other height-gaging units.  Height gages can vary from simple surface gages for measurement transfer and marking to motorized, digital height gages.  Height gages are available with both English and metric incremental scales.

Surface height gages and other surface gaging tools are used for transferring measurements or marking heights.  Surface gages usually do not have indicating display or graduations, but some types are used to hold dial indicators.

Vernier height gages have rulings or graduations engraved or printed onto a set of linear or drum surfaces. The main scale provides an indication of the gaged dimension to an intermediate precision level (e.g., tenths).  The Vernier scale provides additional amplification or an increased level of precision (e.g., thousandths).  Vernier height gages provide more versatility and measurement quantification compared to surface gages.

Micrometer height gages are instruments for precision dimensional gaging.  They consist of a ground spindle and anvil mounted on a horizontal steel frame.  Micrometers are available in scale, digital, and dial variations.  Micrometer height gages provide a higher degree of measurement precision, while sacrificing some versatility, when compared with Vernier height gages.

Digital height gages present metrology data in numeric or alphanumeric form.  Micrometers, calipers, indicators are available in versions with digital displays.  Height gages with digital displays often have data output capabilities using serial or other formats.  Digital readouts are a precision type of digital display integrated into dimensional gages or systems.
