DH-8 takes on
every challenge

Optional PC programmes help DH-8 to easily meet the most challenging requirements. The DIAVITE DH-8 offers the most flexibility when assessing surface finishes. What‘s more, it can be expanded to include contour and optical measurements.

OPTICAL MEASUREMENTS

The DIAVITE DH-8 permits contactless surface measurements

Features

  • Measurement range X: from 0.5 to 15 mm
  • Measurement range Z: max. 400 µm

MEASURING CONTOURS

The DIAVITE DH-8 permits accurate contour measurement. This requires a special measuring tracer and software.

Features

  • Measurement range X: from 0.5 to 15.0 mm
  • Measurement range Z: max. 3 mm
  • Scanning angle: downward flanks to 88 ˚, upward to 77 ˚
