Opisometer
Product Code : JA-M-7888
The Opisometer (SKU JA-M-7888) is a simple instrument for measuring the length of curved lines, such as a route on a map, the outline of a diagram or a curved path drawn in a practical. It consists of a knurled wheel that runs on a transversely mounted threaded spindle, so the position of the wheel along the spindle records how far it has been rolled. This opisometer for measuring curved lines is manufactured in India by JaincoLab for school and college laboratories.

How the opisometer for measuring curved lines is used
To use the opisometer, the wheel is first run to one end of its spindle, rolled along the curved line from start to finish, and then rolled back along a straight scale until it returns to its starting end; the distance covered on the scale is the length of the curve.
- Measuring curved paths and outlines in length-measurement lessons
- Finding the length of a route or river on a map and converting it with the map scale
- Measuring the circumference of circular or irregular drawings
- Checking the length of curved graph lines in practical records
- Geography and physics activities that link measurement with scale drawings

Frequently asked questions
What is an opisometer used for?
It is used for measuring the length of curved lines, for example a route on a map or the outline of a drawing.
How does it work?
A knurled wheel runs on a transversely mounted threaded spindle. The wheel is rolled along the curve and then rolled back along a straight scale to its starting point to read the length.
Is a scale needed with it?
Yes. The measured distance is read by rolling the wheel back along a ruler or a map scale.
