Overview

The Spectra Precision UL633N Dual Grade Laser Level is the industry’s first construction laser to control all three axes, X, Y, and Z,  simultaneously. Built for precision grading, concrete leveling, vertical alignment, and machine control, it delivers unmatched versatility for both horizontal and vertical applications.

The UL633N’s automatic dual-axis system handles grades up to ±25% on all axes, while Grade Match and PlaneLok features ensure slopes and elevations remain steady even on uneven terrain. The Spot Beam functions, Spot Align, Spot Match, and SpotLok, give users precise control for plumb alignment and layout tasks.

Designed for rugged jobsites, the UL633N is IP67-rated, dustproof, and waterproof, withstanding harsh conditions and accidental drops. It communicates via radio or infrared for extended range and can operate up to 800 m (2,600 ft) in diameter when paired with the HL760 receiver.

Powered by a long-lasting NiMH rechargeable battery, it provides up to 35 hours of runtime, while electronic leveling, temperature compensation, and vibration filtering maintain accuracy throughout the workday. Ideal for grading, foundation layout, slope control, and interior alignment, the UL633N is a proven performer trusted by professionals worldwide.
