GL600 Series

Grade Laser

Easy-To-Use, Full Featured Automatic Grade Lasers


The GL612N is a single grade laser and the GL622N is a dual grade laser. Both are rugged, automatic self-leveling lasers featuring grade capability of ±25% and can be used in a wide variety of grading, excavating and alignment applications by general and specialty contractors.

The GL612N and GL622N include the RC602N full-function radio remote control which offers advanced automatic features like Grade Match, PlaneLok and Automatic Axis Alignment. The remote as well as the transmitters have an intuitive graphic display which is back-lit for ease of viewing. Contractors can do everything with the remote control that they can do at the laser keypad, up to 150 meters away—even from the cab of a machine. The ability to make grade changes remotely can significantly reduce setup time and speed operations.

Each laser package also includes the advanced HL760 Digital Receiver that provides a digital readout of elevation and can be used at an operating diameter of up to 800 meters. Wireless communication between the HL760 Digital Receiver and the transmitters provide automatic Grade Matching which allows measurement of unknown grade values between two points.

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. This reduces typical environmental factors that may induce an error. In addition, the HL760 Digital Receiver can communicate with another HL760 for long-range wireless remote display and monitoring.

The GL612N and 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 GL612N/622N Grade Lasers can survive a drop of up to 1 meter  on concrete. The laser also features IP67 moisture and dust sealing to handle the tough construction environment.

The GL612N/622N Grade Lasers retains all well accept functions of the GL500 series lasers with additional advanced features and benefits offering much more versatilities.
