SERIES 120
An analog vernier caliper is a precision measuring tool used to accurately measure external, internal, and depth dimensions of objects. Unlike its digital counterpart, it relies on a manual reading of two scales to determine measurements.
The primary scale provides the base measurement, while the vernier scale provides the precise fraction of that measurement. The alignment of the lines on the main and vernier scales determines the final reading.
Analogue vernier calipers are widely used in mechanical engineering, machining, and various scientific fields for their precision and reliability. They do not require batteries and are generally less susceptible to damage from moisture or magnetic fields compared to digital versions.

Features at a glance
- Main Scale: The main scale is a fixed scale marked on the body of the caliper. It provides the primary measurement in units such as millimeters or inches.
- Vernier Scale: The vernier scale is a smaller, movable scale that slides along the main scale. It is used to read the fractional part of the measurement, allowing for higher precision. The vernier scale typically has graduations that correspond to a fraction of the main scale units.
- Jaws: Outside Measuring Jaws: These are the larger jaws used to measure the external dimensions of an object. Inside Measuring Jaws: These are the smaller jaws located at the top of the caliper, used to measure the internal dimensions of objects, such as the inner diameter of a pipe.
- Depth Rod: A slender rod that extends from the end of the caliper and is used to measure the depth of holes or recesses.
- Thumb Screw or Clamp: A thumb screw or clamp can lock the movable part of the caliper in place, ensuring that the measurement does not change while reading or recording the value.
- Scale and Graduation: The scales are marked with graduations that allow for precise measurement readings. The accuracy of the vernier caliper depends on the smallest division of the main scale and the number of divisions on the vernier scale.
- Measurement Units: Analogue vernier calipers can measure in both metric and imperial units, depending on the scale markings.
