For pipe laying and trench applications, the UL633N can align the plumb beam automatically to the SF601 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 SpotFinder offer additional versatility for 90 degree layout applications on concrete pads as well as indoors for wall layout. Activating the SpotLok mode ensures that the UL633N locks and holds the plumb beam automatically to the SpotFinder at the desired direction or elevation point, providing precise alignment.

The UL633 includes a full-function RC603 Remote Control. The large, easy to see back-lit graphical display is very easy to operate. Contractors can do everything with the remote control that they can do at the laser keypad, up to 330 feet (100 meters) away—even from the cab of a machine or through a pipe.

The ability to make grade changes remotely can significantly reduce setup time and speed operations. With its rugged design, the UL633 can survive a drop of up to 3 feet (1 meter) on concrete. The laser also features IP67 moisture and dust sealing to handle the tough construction environment.

Features:

• Multiple Applications - The Spectra Precision UL633N Universal Laser is 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.
• Automatic self-levelling  - provides fast, easy set-up for horizontal level, grade or vertical alignment
• Automatic Grade Matching - meaning the laser moves to the on-grade position on the receiver automatically by communicating wirelessly with the receiver and the grade is then calculated – this is generally used when a constant fall is desired but the grade may not be known (renewing existing driveways or matching existing surfaces)
• Grade Range - Large, fully compensated grade range from -25% to 25% - keeping the laser levelled no matter what grade you need reducing errors and improving productivity.
• Anti-Vibration Filter - A laser can be affected by high vibration or strong wind, especially when the laser is mounted on a tall tripod –the UL633N has an anti-vibration filter that can be set according to the conditions allowing work to continue regardless of wind conditions or excessive vibrations.
• Temperature compensation & PlaneLok -As temperature fluctuates throughout the working day, the internal components of a laser can expand and contract which can cause some additional error without the user noticing. This is firstly resolved through the automatic temperature check that the laser performs where the internal software calibrates the laser to its optimal performance based on the temperature. Additionally the PlaneLok function can be activated. This keeps the laser beam fixed to a receiver in a set a position eliminating any error that can be caused by fluctuating temperatures, keeping the laser accurate and error free.
• Automatic Axis Alignment - A critical factor when working with grade is alignment to the grade hub. If an alignment is off, error can be introduced and exaggerated. The UL633N has an Automatic Axis Alignment function, allowing the user to set-up simply and quickly, maintaining accuracy and eliminating costly errors. The Automatic Axis Alignment function has the added benefit of being able to simultaneously align on two axes not at 90 degrees to each other. This is especially useful when trying to construct envelope set-ups on a concrete pad or when setting a dual grade for a drainage channel intersecting another channel at an angle not at 90 degrees to the main run.
• Vertical Grade - The Spectra Precision UL633N vertical grade capabilities are enhanced with the use of the SF601 Spot Finder. This accessory allows automatic alignment of the plumb beam. This provides fast alignment to a manhole  on a first day set-up, or to quickly set-out a 90 degree angle. Additionally the Spot Finder can be used to check the grade in pipe on a second day set-up. The beam locks onto the Spot Finder and displays the actual grade on the remote and the laser, saving time and eliminating lengthy manual calculations.
• Rugged - Designed to operate on the toughest of jobsites, the UL633N can withstand a 1m drop directly onto concrete or 1.5m pushover on tripod, eliminating costly repairs.
• Mask Mode - The UL633N has a virtual masking function that allows the laser beam to be turned off in up to 3 sides, avoiding false reading from glass reflections or interfering with other lasers on the same jobsite
