The DIATEST two-piece measuring system is a versatile and adaptable internal diameter gauge.

Multi-functional Aperture Measuring Instrument, capable of measuring aperture sizes ranging from Ø 0.47 to 41.3mm.

Simultaneously measures the aperture diameter and its roundness and ellipticity, particularly suitable for measuring small aperture diameters.

And for high-precision aperture measurements in laboratories, suitable for both manual and automatic aperture measurement.

The built-in elastomer provides continuous force measurement, thereby eliminating human error.

High versatility; can quickly and easily adjust to the desired size within the measurement range of a single probe.

Modular structure, capable of meeting any measurement requirements with various accessories configured.

Measurement Range: Φ0.47-Φ41.1mm (two-point style) Φ4.75-Φ150.6mm (three-point style)

Measurement Depth: Over 2000mm

Repetition Accuracy: ≤1μm - When used with the mounting frame, the repetition accuracy can reach 0.5μm.

Sexual error: ≤1%

In addition to aperture measurement, the two-leaf measuring system can also measure geometric shapes/defects such as ellipticity, concentricity, and barrel shape, etc.
