High-precision digital display vernier caliper

Product Introduction

Calipers, as a classic and practical measuring tool, play a key role in many
fields such as industrial production and scientific research experiments. It is
mainly composed of the master ruler and the vernier ingenious combination, not
to see the structure is not complicated, but has a powerful measurement
function, length, inner and outer diameter and depth and other dimensional
information, can be accurately obtained, for the production and research process
of the size control provides a strong basis.

In terms of range, calipers are available in a wide range of options. Common
specifications are 0 – 150mm, 0 – 200mm, 0 – 300mm and so on. For example, in
scenarios that require delicate operations such as model making and jewelry
processing, the small and flexible 150mm caliper can be used to accurately
measure the size of those small parts. In the processing of mechanical equipment
and hardware, 200mm calipers can meet the measurement needs of various slightly
larger workpieces with a slightly larger measuring range; In the field of
large-scale equipment manufacturing such as machinery, automobiles, and ships,
calipers with a range of 300 mm and above have become the main force, and they
can handle the size measurement of large parts.

The resolution of calipers also varies, with common ones being 0.02mm, 0.1mm,
and 0.05mm. Resolution is directly related to measurement accuracy, taking
0.02mm resolution calipers as an example, it can be accurate to 0.02mm, for
those jobs that require strict dimensional accuracy, such as precision
instrument parts processing, such high-precision calipers are quality assurance.
In general, its accuracy can reach ±0.03mm, although there are some
high-precision models that can achieve an accuracy of ±0.04mm or even
±0.05mm.

In the caliper family, the types are rich and varied. The most traditional
vernier caliper uses the difference between the spacing of the main ruler and
the inverter ruler to read the decimal part, so as to achieve accurate
measurement, and is widely used in various conventional size measurement
scenarios. The caliper with the table uses the tooth pitch of the precision rack
and gear as the known length, and the indicator table is used to magnify,
subdivide and indicate the measured value, which effectively solves the problem
of vernier caliper reading error, and is favored in some occasions that require
higher reading accuracy. The electronic digital caliper keeps up with the pace
of science and technology, using advanced measurement systems such as grating
and magnetic grating, and clearly displays the measurement indication value in
digital form, which not only reads intuitively and conveniently, but also
greatly improves the measurement efficiency, with a common resolution of 0.01mm.
In addition, there are special calipers designed for special measurement needs,
such as hook depth calipers for measuring groove depth, tooth thickness calipers
for measuring gear thickness, height calipers for measuring object height, weld
calipers for measuring welding quality, etc. Regardless of the type of caliper,
they all have their unique advantages and become indispensable measuring tools
in their respective fields.

High-precision measurement:

High-precision measurement: Caliper resolution is commonly 0.02mm, 0.1mm, and
0.05mm. Among them, the caliper with a resolution of 0.02mm can be accurate to
0.02mm, which is a reliable guarantee of quality for work that requires strict
dimensional accuracy such as the processing of precision instrument parts. In
general, its accuracy can reach ±0.03mm, and some high-precision models can even
achieve an accuracy of ±0.04mm or even ±0.05mm.
