HANNOVER, Germany -Trimble introduced new additions to its line of construction lasers-the Spectra Precision GL612 and GL622 Grade Lasers. The GL612 is a single grade laser and the GL622 is a dual grade laser. Both are rugged, automatic self-leveling lasers featuring grade capability of ± 25 percent.

The GL612 and GL622 include the RC602 full-function radio remote control. The remote has 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 100 meters (330 feet) 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 HL750 Laserometer that provides a digital readout of elevation and can be used at an operating diameter of up to 800 meters (2,600 feet). Wireless communication between the HL750 Laserometer 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, and automatically locks the beam on the receiver and keeps it on grade, reducing environmental factors that may induce an error. In addition, the HL750 Laserometer can communicate with another HL750 for long-range wireless remote display and monitoring.

The GL612 and GL622 Grade Lasers self-level in the vertical position for an even wider range of applications, including anchor bolt alignment, concrete tilt-up and curtain wall plumbing.

Both units incorporate automatic temperature and grade compensation for high accuracy in any weather or geographical location. The lasers are built to withstand the rigors of the construction site and can survive a drop of up to 1 meter (3 feet) on concrete.
