2Rotating Lasers / Horizontal and Vertical Dual Grade Laser / FL 510HV-G Tracking

FL 510HV-G Tracking

The ideal outdoor laser

Optimized laser for outdoor applications with automatic axis alignment in horizontal and vertical.

  • Including receiver FR 77-MM Tracking with mm-indication
  • Tracking functions:

    • The laser plane is automatically centred to the receiver “on-grade”

      • Vertical: in both X and Y axis
      • Horizontal: one axis X or Y, other axis horizontal self-levelled
      • Indication of grade value in % after completion of tracking process shown on the instrument and remote control display. Zonal control with electronic beam screen avoids spurious measurements caused by crossing laser planes and reflections – increases site safety

  • Fully automatic self-levelling in horizontal, vertical and grade
  • Slope functions:

    • Horizontal:

      • Digital grade setting of X and Y axis up to ±10 %
      • Manual slope setting of X and Y axis

    • Vertical:

      • Direction of X axis can be set up to ±10 % with Y axis self-levelled
      • Direction of X and Z axis can be set manually

  • Automatic TILT function
  • VWS function (Vibration-Wind-Security)
    Rotation will not be stopped due to light ground and wind vibrations
    (combined with TILT function)
  • Zonal control with electronic beam screen (masking)
  • Fully functional 8-channel 2-way RF remote control
  • Li-Ion battery technology
