Product Description

Overview for Spectra Precision GL622N Dual Grade Laser w/ HL760 Receiver & RC602N Remote Control

The Spectra Precision GL622N is a self-leveling, dual-grade construction laser with long-range operation up to 2,600 feet. With an intuitive keypad and graphic LCD, this rotary laser features automatic axis alignment and offers PlaneLok and grade matching capabilities for highly-accurate results. Capable of tilting on both axes for precise measurement of slopes, the GL622N laser can be used in a wide variety of outdoor grading and excavating. Automatic axes alignments can be accomplished by positioning the laser receiver at the direction hub in a range of ±40° at the desired laser axis. This allows construction professionals to easily perform axis alignments for grade work applications such as sports fields, parking lots, tennis courts, driveways, or any irregular field with non-perpendicular grade profiles.

Ideal for agricultural and construction applications, the Spectra GL622N grade laser delivers a self-leveling accuracy of ±1/16 inch. It also has an automatic dual grade range of ±25% in both axes, providing a fast and easy horizontal level and vertical plumb setup. The self-plumb in the vertical position enables an even wider range of applications such as anchor bolt installation, form, tilt-up, and curtain wall plumbing.

The included Spectra HL760 laser receiver provides a digital readout of elevation and features an anti-strobe detector that prevents false readings from site strobe lights.

The Spectra GL622N incorporates automatic temperature and grade compensation for high accuracy in any weather or geographical location. Mask mode eliminates interference with other crews using a laser onsite and electronic leveling vibration filter reduces vibrations typically experienced on tall tripods, in high winds, or on high vibration job sites. With its rugged design, the GL622N laser level can survive a drop of up to three feet on concrete. It also features IP67 rating moisture and dust sealing to handle the tough construction environment. This dual grade slope laser works up to 35 hours using rechargeable NiMH batteries and approximately 40 hours using alkaline batteries.

Construction professionals can mount this grade laser vertically or horizontally on a 5/8-11 tripod thread.

Configuration Options

The Spectra GL622N has an optional RC602N radio remote control with a backlit display that gives contractors full control of the laser from up to 490 feet away. Please select your preference from the menu above.

  • GL622N-NR: With HL760 Receiver
  • GL622N: With HL760 Receiver & RC602N Remote Control
     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 accept 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.
     Automatic Axis Alignment provides the benefit of simultaneously aligning two axes at 90 degrees to each other.
     90 Degree Layout provides all the references required for a wide variety of interior applications including wall layout and installation, acoustic ceiling installation, point transfer, and tile layout.
     Active Temperature Compensation gives accurate, stable results regardless of temperature changes.
