The Spectra UL633 is the first construction grade laser that offers full automatic control of the X, Y, Z axes. With a working range up to 2,600 feet, this rotary laser provides precise automatic axis alignment, PlaneLok, and grade matching capabilities. It also includes a laser receiver, wireless remote display, and monitoring of slope measurements. With a self-leveling accuracy of 1/16th inch and fully automatic to ±25% grade on all X,Y and Z axes, the versatile UL633 is suitable for both simple and complex grade and concrete work. This Spectra laser facilitates control of the Z axis via automatic detection of the plumb beam, while control of the X and Y axis utilizes a dual radio connection. The UL633 can also be mounted on a 5/8-11 tripod in a vertical or horizontal position.

The Spectra UL633 incorporates automatic temperature and grade compensation for high accuracy in any weather or geographical location. Mask mode eliminates interference and allows the use of multiple lasers on site, while electronic leveling vibration filter reduces vibrations typically experienced on tall tripods, in high winds or on high vibration job sites. This laser level also includes a combined radio and infrared RC603 remote control with a built-in backlit, graphic display that allows you to control the laser up to 330 feet away.
With an IP67 rating, the UL633 is sealed from moisture and dust and is built to survive a drop of up to three feet high on concrete. This dual grade slope laser works up to 35 hours using rechargeable NiMH batteries and approximately 40 hours using alkaline batteries.

Configuration Options

UL633: With HL750 Laser Receiver
The Spectra HL750 laser detector provides a digital readout of elevation and features an anti-strobe detector that prevents false readings from site strobe lights. The readout is displayed on its large front and rear LCDs and shows exactly how far the elevation is from on-grade. Accurate measurements can be made without moving the rod clamp and selectable units of measure can be displayed in millimeter, centimeter, feet, inches or fractional inches. Wireless communication between the HL750 laser detector and the UL633 laser provides automatic grade matching, which allows measurement of unknown grade values between two points. For applications that require maximum stability and accuracy, the PlaneLok feature is available in both horizontal and vertical planes and automatically locks the beam on the receiver and keeps it on grade, reducing typical environmental factors that may cause an error.

UL633-1: With Two HL750 Laser Receivers
Since the UL633 can work with two HL750 laser detectors simultaneously, you can measure an unknown grade value automatically between two elevation points in Grade Match mode. This grade laser can also provide precise automatic axes alignments to two desired points without positioning the two HL750 laser detectors 90 degrees perpendicular. This allows construction professionals to easily perform dual axis alignments for applications such as grade work on sports fields, parking lots, tennis courts and driveways.

UL633-14: With HL750 Laser Receiver and SF601 Spot Finder
The Spectra UL633 is also the first laser where the plumb beam can be changed into a rotating fan beam which can be detected by the Spot Finder. The laser can align the plumb beam automatically to the Spot Finder for pipe laying and trench applications. The combination also offers additional versatility for 90-degree layout applications on concrete pads as well as indoors for drywalls. Measuring a grade value through an existing pipe or an open trench can also be done quickly and easily in automatic Spot Match mode. Activating the SpotLok mode ensures the UL633 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.
