Spectra Precision® GL612 Grade Laser and GL622 Grade Laser — Easy-To-Use, Full Featured Automatic Grade Lasers,
The GL612 Single Grade Laser and GL622 Dual Grade Laser are rugged, automatic self-levelling lasers with grade capability from -25% to + 25% and can be used for a wide variety of grade, excavating and alignment applications by general and speciality contractors.
Both lasers come with a radio remote control that provides fully functional capabilities up to 100m (330 feet) from the laser transmitter – even from the cab of a machine. The graphical, menu driven interface makes the lasers simple and easy to use and can be set to 16 different languages. The ability to operate the laser whilst working away from the laser transmitter can significantly reduce set-up times and increase productivity.
Each laser package includes the advanced HL750 Digital Readout Receiver that can be used at an operating diameter of up to 800m (2,600 feet). The Digital Readout allows the user to get to the on grade position faster as the distance is displayed to the on grade position in mm, or inches, fractional inches. Wireless communication between the receiver and the laser allows advanced functionality such as Automatic Grade Matching to be achieved. Automatic Grade Matching basically means that the laser moves to the on-grade position on the receiver and the grade is then calculated – this is generally used when a constant fall is desired but the grade may not be known (renewing existing driveways or matching existing surfaces). The HL750 can be paired with another HL750 turning the second receiver into a remote display that could allow a machine operator to see what the rodman is seeing when dipping for levels.
Both GL612 and GL622 are self-levelling in vertical, allowing more productivity by being able to carry out more tasks such as building axis alignment or setting 90 degrees or aligning anchor bolts. Designed to be used on the toughest jobsites the GL612 and GL622 can withstand a 1m (3 feet)
