Vernier Height Gauge is a precision measuring instrument used in manufacturing, engineering, and quality control
to measure the height of objects or to mark precise locations on a workpiece. It consists of a vertical scale,
a sliding vernier scale, and a scriber or measuring jaw that can be adjusted to the desired height,
here is the structure of the vernier height gauge as below:
A vernier height gauge key components consists of:
Base: provides stability on a flat surface.
Beam or Column: contains the main scale (usually in millimeters or inches).
Sliding vernier head: carry the vernier scale and a clamping screw.
An auxiliary head which is also attached to the beam above sliding vernier head. It has fine adjusting
and clamping screws.
Measuring Jaw or Scriber: attached to the front of sliding vernier, used to contact the workpiece for measurement
or marking.
The Vernier height gauge uses the same principle as a vernier caliper but is oriented vertically,
especially for the measurement of height. It is equipped with a special base block, sliding jaw assembly,
and a removable clamp.
The upper and lower surfaces of the measuring jaws are parallel to the base, which makes it possible to measure
both over and under surfaces.
A scribing attachment in place of measuring jaw can be used for scribing lines at a certain distance above the surface.
The specification of a vernier height gauge start covers from 0-300mm to 0-1500mm for metric measurement
and from 0-12’’ to 0-60’’ for inch measurement usually.
Advantages of Using a Vernier Height Gauge
High Precision: Offers fine measurement resolution.
Versatility: Can be used for both measuring and marking.
Durability: Made from hardened steel for long-term use.
Cost-Effective: More affordable than digital height gauges while maintaining accuracy.
The Vernier height gauge remains a fundamental tool in metrology, offering reliable and precise vertical
measurements. Whether in machine shops, quality labs, or engineering workshops, it plays a crucial role in
ensuring dimensional accuracy.
