High Resolution Distance Measuring Instrument

Offers extremely accurate distance measurements

The High Resolution Distance Measurement Instrument (HR-DMI) is used in projects where extremely accurate (< 0.1 m) distance measurements are required.

The robust encoder is programmable from 360 to 10,000 pulses per revolution depending on the application.

The HRDMI is a requirement for any ROMDAS system using laser based equipment like LCMS, Transverse Profile Logger or Laser Profilometers. The HR-DMI is not designed for extended use on unsealed roads.
