Dial Test Indicator SENSOR DIATEST 0.8/0.01 — measuring tip travel 0.8 mm, resolution 0.01 mm

The Dial Test Indicator SENSOR DIATEST 0.8/0.01 is a mechanical comparative measuring instrument designed for precise measurement of relative displacement. With a probe travel of 0.8 mm and a graduation of 0.01 mm, this indicator is intended for detecting runout, alignment errors and small form deviations on shafts, housings and fixtures. Its compact design and clear graduation make it suitable for workshop inspection, tool setup and quality control tasks where accurate differential measurement is required.

Advantages

The instrument provides fine resolution of 0.01 mm for repeatable small-displacement readings and a 0.8 mm measuring range that covers common alignment and runout checks. Its mechanical construction offers direct, intuitive readout without reliance on batteries or electronics. The probe mechanism is designed for reliable contact with workpiece surfaces, and the clear dial markings support quick visual assessment during setup and inspection routines.

Suitable for

• Checking runout and concentricity on rotating shafts and spindles
• Alignment of fixtures, chucks and machine setups
• Comparative measurement of small form deviations on machined parts
• Tool setup and inspection in workshops and production lines

Key specifications

• Measuring tip travel: 0.8 mm
• Resolution (graduation): 0.01 mm
• Measurement principle: mechanical dial test indicator
• Readout: analog dial with fine graduation
• Typical applications: runout, alignment, comparative displacement measurement

How to use

Mount the indicator securely to a stable holder or magnetic base so the probe can contact the measured surface at the recommended orientation. Bring the probe tip into contact with the workpiece and set the dial to zero on a reference position if comparative readings are required. Rotate or move the workpiece as needed while observing the dial to record peak-to-peak displacement or incremental deviation. Perform multiple readings at defined points to characterise runout or alignment across the component.

Usage recommendations

For reliable results, ensure the probe tip and measured surface are clean and undamaged, avoid lateral shock to the indicator mechanism, and store the instrument in a protective case when not in use. Calibrate or check zero against a known reference before critical measurements and use appropriate holders to maintain probe alignment.
