The Spectra Precision UL633N Universal Laser is the only construction laser allowing total automatic control of all three axes (X/Y/Z). Control of the Z axis is accomplished through the new “fan beam” technology, while control of the X and Y axis utilizes a dual radio connection. 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. The Universal laser can provide precise automatic axes alignments to two desired points without positioning the receivers 90 degrees perpendicular. This allows contractors to perform easily 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.

On job sites where maximum accuracy and stability is 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 new SpotFinder SF 601.

The UL633N can align the plumb beam automatically to the SpotFinder. Measuring a grade value through an existing pipe or an open trench can also be done quickly and easily in automatic Spot Match mode. The UL633N and the Spot Finder offer additional versatility for 90 degree layout applications on concrete pads as well as indoors for dry walls. 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.

The UL633N includes a full-function combined radio and infrared remote control RC603N, with a built-in back-lit intuitive graphic display. Contractors can do everything with the remote control that they can do at the laser keypad, up to 150 m (500 ft) away from the laser -even from the cab of a machine. The ability to make grade changes remotely can significantly reduce setup time and speed operations. 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.
