What is Vernier caliper
Vernier caliper is a measuring instrument integrated with
scale and caliper. It's the basic measuring instrument for canning industry,
lathe, and milling machine processing site.
scale and caliper. It's the basic measuring instrument for canning industry,
lathe, and milling machine processing site.
The major feature of vernier caliper is the sub-scale (vernier) graduation.
The combination of sub-scale (vernier) graduation and main scale graduation
provides precise numerical reading, 19mm(or 39mm) with 20equal division
(or 50 equal division). The smallest reading value of 20equal division is 0.05mm
and the 50equal division is 0.02mm. The largest reading value have different
types, the standard is 100mm to 1000mm.

Types of Vernier caliper
analog model
 |  |
| • Standard vernier caliper Most common vernier caliper. | • LR type vernier caliper Can be used by both right-handed and left-handed. |
 |  |
| • M type fine adjustment vernier caliper Perform fine adjustment by moving slider. | • Dial caliper Value reading without sub-scale. (Vernier) |
 |  |
| • M type vernier caliper with automatic clamp With automatic thumb clamp. | • Dial caliper Value reading without sub-scale. (vernier) |
 |  |
| • Long jaw vernier caliper Best for measuring larger and deeper objects. |
Types of Caliper
digital model
different than analog vernier caliper, digital caliper
wouldn't have parallax impacts, therefore, it's getting
popular among users.

Methods of reading Vernier caliper
Methods of reading Vernier caliper
The measured value is the reading of scale graduation with sub-scale (vernier) graduation.
The reading method for the pictures below shows graduation value for example
1 is "measured value73.00mm," graduation value for example 2 is
"measured value73.50mm", and for example 3 is "measured value73.55mm".

Methods of reading graduation
To read the measured value, combine main scale graduation with sub-scale (vernier) graduation.
Measured value=Main scale graduation + sub-scale(vernier) graduation
Methods of using Vernier caliper
■ Reading vernier Caliper | Read vernier caliper's graduation from a perpendicular direction, if not, the scale and vernier will create parallax impact due to segment di erence. Align jaw with object's parallel vertical surface. *To provide a solution for parallax impact, dial caliper and digital caliper are developed. |
