ACCURACY FIRST

  • Accuracy certified according to ISO 10360-2 or ASME B89 standard
  • Quick accuracy verification for tactile measurements through conical calibration sockets

MEASURE ANYWHERE

  • True portable system thanks to lightweight carbon-fiber and aluminum alloy components
  • Wireless data communication between arm and PC
  • Battery operation provides > 3 hours of scanning autonomy
  • Universal 3 1/2 "x8 for quick and easy mounting a wide range of mounting options


ERGONOMIC DESIGN

  • 6- or 7-axis version designed for touch probe measurement and laser scanning measurement
  • Electromagnetic brake blocks the lower segment of the arm thus partly bearing the arm weight
  • Ergonomic position of all measurement buttons including brake activation button 
  • Automatic probe recognition retrieves key probe information and eliminates risk of human errors

FLEXIBLE PROBING

  • Metris’  unique floating touch probe assists users in applying constant contact forces, resulting in highly accurate and repeatable measurements.  Instant visual feedback helps the user to qualify his measurement
  • The Metris MMD laser scanner fits both the 6 and 7-axis MCA and offers premium scanning capability and productivity, without requiring an interface box

Technical Specifications

The MCA is available in two variants. The I6 and I7 variants are ideally suited for those applications where a quick verification of dimensions are needed. The M6 and M7 variants provide higher accuracy required for true metrology applications. Both variants come standard with the electromagnetic brake for optimal handling comfort, while the quick mount probe adapter facilitates the easy exchange of measurement probes.
