DIATEST BMD Bore Measuring Instrument
The BMD (Bore Measuring Device) is a high-precision inner diameter bore gauge that can automatically locate the center.
Features high-precision static and dynamic aperture measurement capabilities.
A hole diameter measuring instrument that can be used for manual detection of size deviations and shape defect errors, as well as installed on measuring equipment and automated systems.
Measurement range from Ø 2.98 to 270mm.

DIATEST offers several solutions for diameter and length comparative measurements.
BMD style measuring system, two-leaf measuring system, inside diameter caliper measuring system, and chamfer measuring system.
In addition to length, inner and outer diameters, some solutions can also measure taper, grooves, chamfers, concentricity, and more.

A hole diameter measurement instrument that can be used for manually detecting size deviations and shape defect errors, and can also be installed on measuring equipment and automated systems.
Measurement range from Ø 2.98 to 270mm.

Quickly measure hole diameter, hole roundness, and hole ellipticity
Especially suitable for high tolerance grade through holes in large batch production, both manual and automatic measurements.
Automatic centering, no need to locate the corner points within the hole during measurement
An ideal choice for reading with a digital display and conducting subsequent analysis of measurement results.
The probe of the aperture gauge consists of a hard-chromium plated cylindrical guide and a carbon steel measuring point.
Carbon steel probe transmits the radial movement distance of the measuring point 1:1 to the display meter.
The built-in elastomer provides continuous force measurement, thereby eliminating human error.
The caliper measuring instrument is a modular system comprising a plug-type measuring head, handle, depth extension rod, limit block, and right-angle attachment, with a wide range of applications.
Applicable Range: Through holes, blind holes, tapered holes, stepped holes, square holes, etc.
Measurement Depth: 0.6-2000mm
Repetition Accuracy: ≤1μm
Linear Error: ≤1%
Service Life: Exceeds 1 million measurements requirement
Measurement Range: Φ2.25 - Φ270mm
