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.

Long-range and Versatile Measuring Station 

  • 1” - 1 mm Accuracy.
  • The MS1A is primarily designed for precise construction applications providing 1” (0.3 mgon) angle accuracy and 1 mm + 1 ppm distance measurement precision.

Wide Measurement Range

  • A 200 m reflectorless measurement capability gives MS1A further versatility for applications where reflectors cannot be placed.
  • Measures up to 300 m with 50 x 50 mm reflective sheet targets.
  • Long-range capability reduces the need for changing instrument positions, resulting in higher work efficiency.


Effectively performs displacement and deformation monitoring using state-of-the-art automated measurement capability. 


Measure tunnel convergence and deformation more efficiently.
