Description

The GL622N is a rugged, automatic self-levelling dual grade laser capable of grades from -25% to +25%. It is designed for a wide variety of grade, excavating, and alignment applications by general and specialty contractors. The system provides one-person elevation and grade control with an 800-meter (2,600-foot) diameter range to increase jobsite productivity. It also features automatic axis alignment and PlaneLok technology to maintain high accuracy and eliminate costly errors.

Features

  • Automatic self-levelling for fast, easy setup in horizontal, grade, or vertical alignment.
  • Automatic Grade Matching wirelessly communicates with the receiver to automatically calculate unknown grades.
  • Large grade range from -25% to 25% accommodates a wide variety of project requirements.
  • Anti-Vibration Filter allows continued operation in high wind or excessive vibration environments.
  • PlaneLok function keeps the laser beam fixed to a receiver position to eliminate temperature-induced errors.
  • Rugged design withstands a 1m (3 feet) drop onto concrete, reducing costly repairs.
  • Mask Mode allows the laser beam to be turned off on up to three sides to avoid false readings.
