Vernier Caliper 20cm

The Vernier Caliper 20cm is constructed from lightweight aluminum alloy with stainless steel jaw contact surfaces, featuring a broad fixed upper jaw and a precision-machined sliding lower jaw mounted on a 200mm main scale body. The sliding jaw head carries a vernier subdivision scale for measurements to 0.1mm accuracy. A fine adjustment thumbscrew on the sliding head allows controlled incremental jaw positioning, while a depth measurement blade projects from the instrument base for socket and cavity depth assessment.

The aluminum alloy body construction of this large dental vernier caliper aluminum instrument significantly reduces instrument weight compared to full stainless-steel calipers, minimizing hand fatigue during extended measurement sequences on study models and diagnostic casts. The vernier subdivision scale enables sub-millimeter measurement accuracy beyond standard boley gauge capabilities. This 200mm orthodontic caliper gauge is fully autoclavable at 134°C, maintaining jaw alignment, vernier scale legibility, thumbscrew function, and aluminum body dimensional stability through repeated sterilization cycles without warping or corrosion.

The Vernier Caliper 20cm is used by orthodontists, prosthodontists, and oral surgeons during comprehensive arch analysis, full-arch width measurement, facial dimension assessment, and large diagnostic cast measurement procedures. Using this Vernier Caliper 20 instrument, the clinician positions the jaws against opposing anatomical landmarks, advances the sliding jaw to firm contact, reads the main scale millimeter value, then adds the vernier subdivision reading to obtain precise sub-millimeter dimensional measurements across extended arch and facial measurement ranges.

Leader Surgical addresses the measurement gap between compact boley gauges and full laboratory calipers with this 200mm aluminum instrument, providing orthodontic and surgical teams with a lightweight, autoclavable large-range caliper that delivers vernier-scale sub-millimeter accuracy across the extended measurement distances that standard dental gauges simply cannot reach.

What can I measure with this caliper?
It is designed for four-way measurement: external (outer diameter), internal (inner diameter of holes), depth (using the protruding rod), and step (the difference in height between two surfaces).
