These lasers offer automatic self-leveling in grade, horizontal and vertical planes.  They feature  grade capability of ± 25% and  can be used in a wide variety of grading, excavating and alignment applications by general and specialty contractors.

The GL622N is a dual slope grade laser. This rugged, automatic self-leveling laser has a grade capability of ± 25% and can be used in a wide variety of grading, excavating and alignment applications by general and specialty contractors. An intuitive keypad and graphic display makes all grade and alignment functions easy to use and greatly reduces setup time and increases productivity.

 

Grade Match:  Wireless communication between the HL760 Digital Receiver  and the transmitter provide automatic Grade Matching which allows measurement of unknown grade values between two points.

Plane-Lok: For applications that require maximum stability and accuracy, PlaneLok is available in both the horizontal and vertical planes. PlaneLok automatically locks the beam on the receiver and keeps it on grade, reducing typical environmental factors that may induce an error.

Automatic Axis Alignment (GL622N  only): 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 contractors to easily perform dual axis alignments for grade work applications such as sports fields,  parking lots, tennis courts, driveways or any irregular field with non-perpendicular grade profiles

The GL622N Grade Lasers self-plumb in the vertical position to allow an even wider range of applications such as such as anchor bolt installation, form, tilt up, and curtain wall plumbing.

With its rugged design,  the GL622N  lasers can survive a drop of up to 3-feet on concrete. The lasers also feature IP67 moisture and dust sealing to handle the tough construction environments.
