Dial Indicator Thickness Gauge

The Mitutoyo 7315A is a high-quality analogue thickness gauge that combines the accuracy of a mechanical dial gauge with a more specialized contact system for measuring grooves, thin material, and pipe walls. This measuring tool is particularly suitable for situations where the target to be measured is located in a narrow groove or on internal surfaces, and accurate and repeatable measurement is required.

The gauge offers a measuring range of 0–10 mm and a scale division of 0.01 mm increments. The maximum accuracy is ±0.015 mm, and the parallelism accuracy is 5 µm. The point of contact is a knife-edge anvil tip that reaches into grooves and constricted areas – this allows measurement of pipe walls, plates, or pockets, for example, where a conventional gauge cannot reach. The measuring force is up to 1.4 N, ensuring controlled contact with the surface to be measured without unnecessary pressure.

In addition, the design incorporates a ceramic-coated contact point for improved wear resistance and protection against corrosion. Measuring to a depth of approximately 30 mm, the model covers slightly deeper areas. The gauge is ergonomically designed: its handle, trigger, and dial system make it easy to use in a production environment without compromising accuracy.

The Mitutoyo 7315A is the clear choice when a mechanical thickness gauge is required that combines the ease of analogue reading, the versatility of the specialized tip, and the accuracy of measurement. It is ideal for applications such as pipe wall measurements, thin film or paper thickness measurements, and quality control in serial production where the targets to be measured may be located on internal surfaces or in groove niches.
