Electronic Digital Level DL-501

Technologies for Precision

The DL-501 series incorporates an array of advanced technologies to achieve the highest leveling accuracy in the industry.

  • RAB-Code technology, superior optics, market-proven compensator and magnetic damping system ensure precise staff readings.
  • Dual-axis compensator notifies instrument tilt, Remote Trigger prevents accidental jolts, and Auto Focus (DL-501 Advanced model) eliminates incomplete focusing. These unique technologies remove major error factors.
  • Even in the dim light conditions, if the staff surface brightness is 20lx or more, the DL-501 series can read the staffs without compromising accuracy.

Technologies for Speed

Both models feature the measurement time of 2.5 seconds - the fastest in its class. The DL-501 Advanced model, equipped with Auto Focus and View Finder for quick sighting, saves measurement time by up to 40% compared to manual focus digital levels.

Measurement Programs

Onboard program supports line leveling and data recording.

  • Methods: BF, BFFB, BBFF, BFBF, aBF, aBFFB, aFBBF
  • Up to two intermediate sights can be measured in each set.
  • Adjustable tolerances and error calculation functions allow for on-site accuracy checks.
