diast-col

The diast-col collection covers precision instruments for dimensional measurement and geometric inspection of parts, machined components, and assemblies. These tools are used to verify tolerances, support quality control, and fine-tune manufacturing processes—whether in a metrology lab or directly on the shop floor.

Here you’ll find multiple measurement principles and accuracy classes, including digital and analog instruments designed for internal/external dimensions, depth, and step measurements. Options are available with high resolution, strong repeatability, ergonomic handling, and durable construction for demanding environments, from Insize, Mitutoyo & PCE.

They are widely used by engineers, CNC technicians, QC inspectors, and maintenance teams across metalworking, precision machining, plastics, tooling/mold making, and industrial automation—anywhere measurement traceability and consistent results are essential.
