Ultra-Precision Measuring Station

0.5” Angle Accuracy
The MS05A employs innovative Independent Angle Calibration System (IACS) technology for unparalleled measurement reliability. Combined with market proven absolute encoders that incorporate advanced coding and digital-processing technologies, the MS05A provides the industry’s highest 0.5” (0.15 mgon) angle measurement precision.

The Sub-millimeter EDM opens the door to unprecedented precision
Cutting-edge distance measurement technology ensures unparalleled comprehensive performance. Using reflective sheet targets, the MS05A provides sub-millimeter accuracy with a range of up to 200 m. With its 3.5 km prism-mode long-range capability and fast measurement speed, the MS05A also satisfies every requirement for the reference EDM that is employed for precise baseline calibration.

  • Sub-millimeter 0.5 mm + 1 ppm accuracy using reflective sheets within the range of 200 m.
  • Measures prisms with 0.8 mm + 1 ppm precision up to 3,500 m.
  • Reflectorless measurement can be performed with 1 mm + 1 ppm up to 100 m in range.
Effectively performs displacement and deformation monitoring using state-of-the-art automated measurement capability.
Measure tunnel convergence and deformation more efficiently.
Civil Engineering
Major Civil engineering tasks demand the highest accuracy and reliability possible. The MS05A/MS1A dramatically increases construction efficiency and accuracy with its superior measurement capability in combination with unique target systems.
Precise measurements using reflective sheet targets and compact prisms enable high-quality bridge construction with short lead times.
Plant and Process Engineering
Position, geometry and dimensions of complex members of various plants can be measured with sub-millimeter accuracy.
When absolute accuracy is required and no compromise is allowed, the MS05A provides a flexible solution for the precise measurement of dimensional stability and geometry of important structures.
