Overview for the Spectra GL622 Dual Grade Laser

The Spectra GL622 is a self-leveling, dual-grade construction laser with long-range operation up to 2,600 feet. With an intuitive keypad and graphic display, this rotary laser features automatic axis alignment and includes a HL750 laser receiver that offers PlaneLok and grade matching capabilities for highly-accurate results. Capable of tilting on both axes for precise measurement of slopes, the GL622 laser can be used in a wide variety of outdoor grading and excavating.

Self-Leveling and Axis Alignment

Ideal for agricultural and construction applications, the GL622 grade laser delivers self-leveling accuracy of 1/16th inch. It also has automatic dual grade range of ±25% in both axes, providing 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. You can also mount this device vertically or horizontally on a 5/8-11 tripod thread.

Automatic axes alignments can be accomplished by positioning the 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. 

Spectra HL750 Laser Receiver

The advanced HL750 laser receiver provides a digital readout of elevation and can be used at an operating diameter of up to 2,600 feet. It features an anti-strobe detector that prevents false readings from site strobe lights. The readout is displayed on its large front and rear LCD's and shows exactly how far the elevation is from on-grade. Accurate measurements can be made without moving the rod clamp, saving time and increasing productivity. Selectable units of measure can also be displayed in millimeter, centimeter, feet, inches or fractional inches.

Wireless communication between the Spectra HL750 laser detector and the GL622 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.

Extra Features

The GL622 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 jobsites. The Spectra GL622 includes a RC602 radio remote control, which has a backlit graphic display and gives you full control of the laser from up to 330 feet away.

With its rugged design, the GL622 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.

This Spectra dual grade laser package comes with a HL750 laser receiver, remote control, rod clamp, carrying case, NiMH rechargeable battery pack, charger, AC power cable and a 5-year manufacturer’s warranty.
