L-731 PRECISION LEVELING LASER WITH PLUMB BEAM

DESCRIPTION
The L-731 Precision Leveling Laser combines a very flat plane of light for quick, easy flatness and level measurements and a plumb laser for measuring squareness. It has an integrated precision leveling base with 2-arc-second (0.00012"/ft or 0.01 mm/M) level vials and pitch and roll adjustments for making the laser plane or beam parallel to reference points.

The laser plane is flat to 2 arc seconds in a 360º sweep and 1 arc second (0.00006" or 0.005 mm/M) in a 90º sweep. It has an operational range of 100 feet (30.5 meters) in radius. The plumb laser beam is square to the laser plane to within 2 arc seconds.

Three switches (LASER & SCAN, LASER ONLY, and OFF) control the laser beam, and the level vials are backlit for easy reading. There is also variable speed control for the laser rotation. The diode laser is low power (less than 1 mW) and visible to the naked eye for easier setup.

APPLICATIONS (for alignments with tolerances of 0.00012"/ft or (0.01 mm/M) or greater)

  • General machine leveling
  • Checking squareness between machine axes
  • Checking plumb of machine columns or fabrications
  • Checking the flatness of almost any surface (squares, frames, ways, flanges, circles, etc.)
  • Measuring and leveling machine beds and ways, large bearing surfaces, and fabrications
  • Checking way twist and parallelism between horizontal surfaces
  • Aerospace tooling leveling/floor alignment
  • Turbine split-joint leveling/measuring
  • Continuous casters
  • Antenna arrays
