VERNIER HEIGHT GUAGE

3. BASIC INTRODUCTION
• Vernier height gauge, is a widely used bench
top tool. A height gauge is a measuring device
used either for determining the height of
something, or for repetitious marking of item.
• These measuring tools are used in
metalworking or metrology to either set or
measure vertical distances.

4. BASIC CONSTRUCTION
• A height gauge has a vertical column. A unit is
attached to this column which slides up and down.
• An arm protrudes from the gauge coming into direct
contact with the part being measured.
• Each height gauge features a solid base giving the
vertical column enough stability that it remains at a
right angle to the table’s surface.
• The moving slide is engraved with vernier calibrations
enabling setting to an accuracy of 0.02 mm.
• The height of the scribe’s point can be finely adjusted
with a thumbscrew .

6. Working
1. The work to be marked out with a vernier height gauge
must be set vertically on a surface plate.
2. The height of the scribe is set with the moving slide’s fine
adjusting screw.
3. The marking out lines are then scribed onto the work’s
surface by steadily moving the vernier height gauge along
the surface plate .
4. On some vernier height gauges, the height of the main
scale can also be finely adjusted.
5. This enables measurements to start from a convenient
reading, which is useful if the shape of the work piece is
such that it needs to be mounted on a parallel strip .

7. Applications
• These are used to mark out lines and widely
used on surface plates and on machine tables.
• The height gauge with an indicator
attachment is used for checking of surface
holes.
• The height gauge with a scribe attachment is
used to mark reference lines and locations on
castings and forgings
