Purpose:
1. Radius measuring tool can be used for measuring arc of incomplete circle ,especially find out the radii through measuring minor arc.
2. Radius measuring tool can obtain radii of the workpiece when mapping the workpiece or other object.
3. Radius measurement tool can be applied to archaeological study,it is help for recovery the relic’s radii.
A digital radius caliper is used to measure the radius dimensions of objects
that do not have a complete circle or when it is inconvenient to measure the radius of a full circle.
Point A,C,E are three tangential point between the caliper and the workpiece.R is the radii of the workpiece. If: α = 73°44′, Then,circular function: BD = R.
| Range | Resolution | Accuracy |
|---|---|---|
| 3-150mm / 6" | 0.01mm/0.0005" | ±0.03mm |
| 3-200mm / 8" | 0.01mm/0.0005" | ±0.03mm |
