The Spectra Precision UL633N Universal Laser is the only construction laser that allows full control of level, alignment, single/dual grade, and vertical applications, delivering maximum versatility on the jobsite. Designed for use on general construction and interior layout, it controls all three axes (X, Y, Z) simultaneously with automatic dual-axis features and advanced “fan beam” technology for the Z-axis.
Its Automatic Grade Matching function quickly determines and sets unknown grades, while the Automatic Axis Alignment ensures precise positioning even when grade hubs aren’t perfectly aligned. The PlaneLok feature locks the beam to a fixed elevation, eliminating errors caused by temperature changes. A built-in Anti-Vibration Filter maintains accuracy in high winds or on tall tripods.
Built to withstand tough site conditions, the UL633N can survive a 3 ft (1 m) drop onto concrete and is protected to IP67 standards. With an operating diameter of up to 2,600 ft (800 m) and a ±25% grade range on all axes, it delivers unmatched flexibility for grading, layout, and alignment work.
