Opisometer
A practical instrument for measuring the length of curved lines with accuracy. It is fitted with a knurled wheel and index mark, mounted on a U-bracket with threaded spindle, and supported by a rear handle for ease of use. The length is determined by multiplying the number of wheel rotations by the wheel’s circumference.
Highlights:
- Measures curved line lengths accurately
- Knurled wheel with index mark for precision reading
- Mounted on a sturdy U-bracket with threaded spindle
- Convenient rear handle for smooth operation
- Simple calculation method: rotations × circumference
