• Laser only
• The only construction laser that provides the ability to control level, alignment, single/dual grade, and even do grade in vertical allowing you to do more work with one tool
• Provides fast, easy set-up for horizontal level, grade, or vertical alignment
• Large, fully compensated grades range from -25% to 25% – keeping the laser leveled no matter what grade you need reducing errors, and improving productivity
• An anti-vibration filter can be set according to the conditions allowing work to continue regardless of wind conditions or excessive vibrations

The Spectra Precision UL633N Universal Laser is the only construction laser allowing total automatic control of all three axes (X/Y/Z). Benefiting of all the know-how of Spectra Precision, the UL633N Universal Laser is appropriate for all applications producing an easy, fast, and accurate job. This allows contractors to easily perform dual axis alignments for applications such as grade work on sports fields, parking lots, tennis courts, and driveways. Since the UL633N Universal Laser can work with two receivers simultaneously, contractors can measure an unknown grade value automatically between two elevation points in Grade Match mode. Receivers sold separately

On job sites where maximum accuracy and stability are required such as airport runways, elevations can be precisely secured using the automatic Dual Axis PlaneLok feature. This capability locks and maintains the laser reference plane to two receivers placed at existing elevation points, eliminating drift or possible errors caused by vibrations or temperature changes. The UL633N Universal Laser is also the first laser where the plumb beam can be changed into a rotating fan beam which can be detected by the SpotFinder SF601.

The UL633N and the Spot Finder offer additional versatility for 90-degree layout applications on concrete pads as well as indoors for wall layout. Activating the SpotLok mode ensures the UL633N locks and holds the plumb beam automatically to the Spot Finder at the desired direction or elevation point offering a precise alignment to avoid rework.

With its rugged design, the UL633N can survive a drop of up to 1 meter (3 feet) on concrete. The laser also features IP67 moisture and dust sealing to handle the tough construction environment. The UL633N Universal Laser retains all well accept functions of the GL500 series lasers with additional advanced features and benefits offering much more versatilities.
