Centesimal dial test indicator Kafer – SA022K

The centesimal dial test indicator Kafer is designed for comparative inspections where the measuring point cannot be easily reached with a traditional plunger dial indicator. It is especially useful when contact with the component must occur laterally, on inclined surfaces, edges, shoulders or in areas where a standard dial indicator is less practical.

The operating principle is simple: the contact tip touches the component and the small oscillation of the lever is transferred to the internal mechanism, converting the movement into pointer displacement on the dial. This allows immediate reading of deviations from the reference setting.

This centesimal dial test indicator is particularly useful for checking concentricity, eccentricity, parallelism and flatness, as well as for centering and alignment of components on machine tools. It helps the operator verify positioning errors during setup and adjustment operations.

In setup activities on milling machines, lathes, grinders and other machine tools, the dial test indicator is practical because it allows inspection on lateral surfaces or diameters with immediate deviation reading. This makes it useful when a component must be positioned correctly before machining.

The 0.01 mm reading identifies this model as a centesimal dial test indicator. The range includes versions with 0.8 mm or 0.5 mm measuring range, 32 mm or 40 mm dial diameter and different stylus lengths depending on the model.

From a practical point of view, the centesimal dial test indicator is suitable both for bench inspections and direct machine inspections. It is selected whenever small deviations must be checked with a configuration more suitable for lateral measurements, external surfaces and centering operations.

Applications

• Comparative inspection of deviations on lateral surfaces
• Verification of eccentricity and concentricity
• Inspection of flatness and parallelism
• Measurements on shoulders, edges and difficult-to-access areas
• Inspection on external diameters and inclined surfaces
• Centering and alignment of components on machine tools
• Verification of correct positioning during machining setup
• Use in workshops, tooling and quality control departments

FAQ – Centesimal dial test indicator

What is a centesimal dial test indicator?
It is a comparative measuring instrument with 0.01 mm reading, where contact with the component occurs through a measuring lever.

What is the centesimal dial test indicator used for?
It is used for comparative inspections on lateral, inclined or difficult-to-access points, and for centering or alignment on machine tools.

Is a dial test indicator the same as a lever-type test indicator?
Yes, these terms are commonly used to describe the same type of instrument.

How does a dial test indicator work?
The contact tip touches the surface, the lever oscillates and the movement is shown on the dial as a deviation from the reference.

When is it better than a traditional plunger dial indicator?
When the inspection point is lateral, inclined or not easily accessible from the front.

Which inspections is it most commonly used for?
It is commonly used for concentricity, eccentricity, parallelism, flatness and comparative checks on external or lateral surfaces.

Is it useful on machine tools?
Yes, it is widely used for centering and alignment of components or fixtures on machine tools.

What reading does this model have?
This model has a 0.01 mm reading.

Which measuring ranges are available?
Versions with 0.8 mm and 0.5 mm measuring range are available.

Which dial sizes are available?
The series is available with 32 mm or 40 mm dial diameter.

Why are different stylus lengths available?
Because different lengths allow the instrument to adapt better to access conditions and component geometry.

Who is this instrument recommended for?
It is recommended for workshops, tooling departments and quality control where comparative inspections, centering and alignment operations are carried out.
