Unlike a conventional rotary or dual grade laser, the UL633N provides automatic control across the X, Y and Z axes, allowing it to perform horizontal levelling, single and dual grade, vertical alignment and specialised layout tasks with one instrument.

With a fully compensated grade range of up to ±25%, Automatic Grade Match, PlaneLok and Automatic Axis Alignment, the UL633N is particularly well suited to civil construction, concrete work, drainage, site preparation and complex grading applications where accuracy and efficient setup are critical.

The package also includes two Spectra HL760 digital receivers and an SF601 SpotFinder, providing a complete professional system for grade, alignment and layout work.

Three-Axis X, Y and Z Control

The UL633N is designed to provide automatic control across all three axes.

Traditional X and Y axis control handles horizontal levelling and grade applications, while Spectra’s specialised fan-beam technology enables control of the Z axis for vertical alignment and layout.

This makes the UL633N suitable for applications including:

• Single and dual grade work
• Drainage and earthworks
• Concrete pads and slabs
• Site preparation
• Driveways and ramps
• Vertical alignment
• Wall and formwork layout
• 90-degree layout
• Complex intersecting grades
• General construction levelling

Up to ±25% Grade Capability

The UL633N provides a large, fully compensated grade range of ±25% on the X and Y axes, as well as up to ±25% on the Z axis.

This extended grade capability allows contractors to establish significant slopes while maintaining an accurate laser reference, making the UL633N particularly useful for civil, drainage and earthmoving applications.

Automatic Grade Match

Automatic Grade Match allows the UL633N to automatically locate the on-grade position at a receiver and calculate the resulting grade.

This is particularly useful where an existing slope needs to be replicated but the exact percentage is unknown.

Typical applications include:

• Matching existing driveways
• Reinstating existing surfaces
• Drainage work
• Matching ramps or graded areas
• Extending an established fall

Rather than manually calculating the existing slope, the laser and receiver communicate to determine the required grade automatically.

Automatic Axis Alignment

Correctly aligning a grade laser with a grade hub is critical, as even a small alignment error can become significantly larger over distance.

The UL633N’s Automatic Axis Alignment function helps automatically align the laser axis with the required grade direction, reducing setup time and helping eliminate costly alignment errors.

The system can also align two axes that are not positioned at 90 degrees to one another.

This can be particularly valuable when constructing complex concrete pads or drainage channels where two graded surfaces intersect at an irregular angle.

PlaneLok for Consistent Accuracy

The PlaneLok function locks the laser plane to a receiver at a fixed position.

This helps compensate for changes that might otherwise affect the reference plane, including temperature fluctuations or movement over extended periods of operation.

PlaneLok is especially useful for long-duration construction work where maintaining a consistent reference elevation or alignment is important.

SF601 SpotFinder Included

The included SF601 SpotFinder automatically detects the UL633N’s plumb or fan beam.

This provides additional capability for:

• 90-degree layout on concrete pads
• Vertical alignment
• Wall layout
• Interior construction
• Transferring alignment points

The SpotFinder can be used for both manual and automatic detection of the plumb beam.

Two HL760 Digital Receivers Included

The UL633N package includes two Spectra HL760 advanced digital laser receivers.

The HL760 provides a digital readout of the receiver’s position relative to grade, allowing the operator to see the actual offset rather than relying solely on directional arrows or audible signals.

Having two receivers also enables advanced UL633N functions such as automatic axis alignment and complex grade setups.

Anti-Vibration Filter

Construction lasers mounted on tall tripods can be affected by strong winds, ground movement and machinery vibration.

The UL633N includes an adjustable anti-vibration filter that allows the laser to continue operating reliably under challenging site conditions.

This can help reduce interruptions and unnecessary resets on active construction sites.

Mask Mode

The UL633N includes a virtual Mask Mode that allows the rotating laser beam to be turned off on up to three sides.

This can help:

• Prevent reflections from glass or reflective surfaces
• Reduce interference with other lasers
• Avoid unwanted laser signals on neighbouring work areas
• Improve receiver reliability on busy construction sites

Rugged IP67 Construction

The UL633N is engineered for demanding professional environments and carries an IP67 dust and waterproof rating.

It is designed to withstand:

• A drop of up to 1 metre onto concrete
• A tripod tip-over of approximately 1.5 metres
• Dust, rain and demanding jobsite conditions
• Operating temperatures from -20°C to +50°C

The UL633N is also backed by a 5-year manufacturer warranty.

The Spectra Precision GL422N Dual Grade Laser was designed for a wide range of general construction, site preparation, and excavations. This rugged, automatic slope laser provides contractors with accurate levelling, grade, and vertical alignment. With a working range of up to 2,600 feet, it has a grade capability of –10 to +15 percent on both axes. The GL422N is also self-levelling horizontally and vertically within ±5 degrees and has an accuracy of ±1/16 inch per 100 feet. For anchor bolt and form alignment, it self-plumbs in the vertical position and can be mounted on a 5/8-11 tripod thread vertically or horizontally.

The Spectra RC402N full-function remote control comes optional with the GL422N grade laser and offers an easy to use menu-driven interface. With a working of up to 330 feet, this radio remote gives the ability to make long-range grade changes and automatic alignments. The Spectra GL422N has an out of level alert that shuts off the grade laser if it is knocked out of place to prevent inaccurate readings. It also has a selection of sensitivity for accurate results even in high winds or on high vibration job sites.

With an IP66 rating, this laser level is dust-proof and can be used in heavy rain. It can also withstand drops of up to three feet onto concrete and tripod tip-overs up to five feet. This slope laser uses NiMH batteries and works up to 35 hours of continuous use.

GL422N Grade Laser Kit Components:

• GL422N: With HL760 Receiver & RC402N Remote Control

The Spectra HL760 with digital readout of elevation is a highly versatile laser receiver for basic and advanced levelling and aligning applications. With a unique fingerprint function, it is easily paired with the GL422N to detect only its laser beam and avoid conflict between other laser levels working in close proximity. This laser receiver also provides automatic grade matching and PlaneLok to eliminate manual slope adjustments and errors due to improper calibration or weather.

	No Cost 5-Year Warranty offers no repair charge for parts and labor of the laser.
	Shock Proof ensures this construction laser withstands a three feet drop onto concrete.
	Included Radio Remote control is easier to use because it does not have to be aimed at the laser for it to work. This increases the flexibility of the laser for long-range setups while maintaining outstanding accuracy.
	Fingerprint function filters out other lasers that strike the receiver and only accepts the laser that it is paired with.
	Grade Match enables contractors to measure an unknown grade value automatically between two elevation points.
	Dual Axis PlaneLok keeps the laser beam fixed to a receiver in a set position, making it accurate and error free.
