The Spectra Precision GL622N is a full-featured dual grade laser designed for demanding construction jobsites where precision grading on both axes is essential. With a ±25% grade range on both X and Y axes, this laser delivers the accuracy and flexibility contractors need for complex earthwork, drainage, and foundation projects.
Built for rugged field conditions, the GL622N features IP67 water and dust protection, surviving the harshest jobsite environments. The self-leveling capability (±14°) reduces setup time and ensures accurate readings even on uneven terrain. Rotating at 300, 600, or 750 rpm, the laser provides dependable line-of-sight coverage up to 800 meters, keeping your crew productive across large project areas.
Accuracy is paramount on any jobsite. The GL622N delivers ±0.5mm/10m leveling accuracy and ±1.0mm/10m grade accuracy, meeting the precision requirements of professional contractors. Anti-vibration filtering smooths beam stability, while Automatic Grade Matching simplifies setup by automatically adjusting to detected slope. PlaneLok prevents accidental grade shifts during operation.
The 35-hour NiMH battery provides all-day runtime on a single charge, eliminating mid-shift downtime. An infrared version (GL622IR) is also available for applications where visible laser beams are prohibited, including rail work and indoor construction. Both models include a comprehensive 5-year warranty, protecting your equipment investment.
Whether you're grading for concrete slabs, drainage systems, or highway construction, the GL622N combines precision, durability, and field efficiency to keep projects on schedule and within specifications.
