Description

Details

The Spectra Precision GL422 Grade Laser is a cost-effective, automatic self-leveling laser that does three jobs - level, grade and vertical alignment with plumb. Features a 2-way, full-function remote control so you can make grade changes from anywhere on the job site for reduced setup time and faster operation. Sends a continuous, self-leveled 360-degree laser reference over your entire work area, and have a wide grade range so they can be used in a variety of slope applications. Fast, easy horizontal level, grade and vertical plumb setup with no manual leveling. Automatic temperature and grade compensation eliminates rework. The laser beam can be turned off electronically on up to 3 sides of your choice. This capability eliminates interference with other crews on the job site by keeping the beam from straying into other work areas. Features a 2-way, full function remote control with a built-in back-lit grade display. You can do everything with the remote control that you can do at the laser keypad, including grade reverse on both axes, up to 100 m (330 ft) away from the laser - even from the cab of the machine. The GL422 offers two additional advanced features: pointing mode for “Over the Top” pipe laying applications and grade match where the laser can be used to measure the existing grade value between two known elevation points. This package also includes the HL700 Laserometer with highly visible LED display and dual sided LCD’s and an anti-strobe sensor. Digital readout of elevation shows how far from on grade without moving the rod clamp. Large 127 mm (5 inch) reception height acquires the beam quickly and keeps you in the laser beam. Extremely tough, can withstand a drop of 3 m (10 ft) onto concrete and has a 3 year warranty.
