The Spectra Precision GL622IR brings the precision and capability of the GL622N dual grade laser to applications where visible laser beams cannot be used. This infrared version projects a Class 1 invisible 830nm beam, making it the ideal choice for rail construction, indoor work, and specialized environments requiring invisible laser technology.
Contractors working on railway projects, indoor tunneling, or locations with strict laser beam regulations will appreciate the GL622IR's seamless integration into restricted-beam environments. The infrared technology delivers identical performance to the visible GL622N—±25% grade range on both axes, ±0.5mm/10m leveling accuracy, and ±1.0mm/10m grade accuracy—without the visibility concerns.
Durability in the field is guaranteed with IP67 water and dust protection, allowing operation in rain, mud, and debris-laden jobsites. The self-leveling range of ±14° reduces setup time on uneven terrain, while the anti-vibration filter ensures stable, accurate beam projection. Rotating at 300, 600, or 750 rpm, the GL622IR maintains consistent coverage across distances up to 800 meters.
Extended battery life keeps crews working longer. The 40-hour NiMH battery provides nearly two full workdays of continuous operation, reducing the need for frequent recharging and minimizing jobsite delays. Automatic Grade Matching and PlaneLok features simplify operation, allowing operators to focus on accuracy rather than equipment management.
For contractors and engineers requiring dual-axis grade control in restricted-beam environments, the GL622IR combines invisible infrared technology with professional-grade precision, accuracy, and rugged field durability. The 5-year warranty protects your investment across multiple project seasons.
