What is Vernier caliper
Vernier caliper is a measuring instrument integrated withscale 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 graduationprovides precise numerical reading, 19mm(or 39mm) with 20equal division(or 50 equal division). The smallest reading value of 20equal division is 0.05mmand the 50equal division is 0.02mm. The largest reading value have differenttypes, the standard is 100mm to 1000mm.

Types of Vernier caliper
analog model
 |  |
| • Standard vernier caliperMost common vernier caliper. | • LR type vernier caliperCan be used by both right-handedand left-handed. |
 |  |
| • M type fine adjustment vernier caliperPerform fine adjustment bymoving slider. | • Dial caliperValue reading without sub-scale.(Vernier) |
 |  |
| • M type vernier caliper with automatic clampWith automatic thumb clamp. | • Dial caliperValue reading without sub-scale.(vernier) |
 |  |
| • Long jaw vernier caliperBest for measuring larger anddeeper objects. |
Types of Caliper
digital modeldifferent than analog vernier caliper, digital caliperwouldn't have parallax impacts, therefore, it's gettingpopular among users.
 | |  |  |
| • Digital caliperMost common digital caliper. | • Hole pitch digital caliperQuick measurement of distance between hole center. |
 |  |
| • Carbide tipped digital caliperBest to use on measuring rough, grindstone, and casting processed products. | • Digital inside caliperThe specially designed long knife-edge jaws makes insidemeasuring easier. |  |
 |
| • Digital scriber caliperHas the function of measurement and scriber. |  | |

Methods of reading Vernier caliperanalog model
Methods of reading Vernier caliperanalog model 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 example1 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 aperpendicular direction, if not, the scaleand vernier will create parallax impact dueto segment di erence.Align jaw with object's parallel verticalsurface.*To provide a solution for parallax impact, dial caliperand digital caliper are developed. |
■ Methods of apply vernier caliper to measuring object
 | - Square object measurementAlign jaw with object's parallel vertical surface.
- Round object measurementGrip on the axis of the round object with vernier caliper's jaw at a right angle.
*Measured error will occur if the right angle is notaccurate. |
