Dial test indicators

Dial test indicators, also known as lever-type indicators, are measuring instruments used for comparative checks on surfaces, concentricity, flatness, and mechanical alignment. Thanks to the lever system with adjustable contact point, they allow dimensional inspections to be carried out even in hard-to-reach areas or on components with complex geometries.

A dial test indicator works through a side contact that transfers movement to an internal mechanism with a high-sensitivity analogue dial. This configuration allows very small dimensional variations to be detected during centring, alignment, and geometric checks directly on lathes, milling machines, grinding machines, and other machine tools.

Dial test indicators are frequently used in precision machining to check eccentricity, radial runout, parallelism, and concentricity. The adjustable lever makes measurement easier from different angles, improving accessibility when checking shafts, holes, ground surfaces, and complex mechanical parts.

The range includes centesimal and micron dial test indicators, also available in vertical, shockproof, and high-sensitivity versions for advanced metrology applications. The highly readable dial allows fast and immediate reading of dimensional variations, while the compact structure makes these instruments particularly suitable for direct use in production.

Used together with magnetic bases and support systems, dial test indicators are an essential solution for quality control and geometric inspection in industrial and metrology applications. Their high sensitivity allows reliable and repeatable checks even during high-accuracy machining operations.
