Features & Benefits
GL612N / GL622N are grade lasers with a compensated grade range of -25% to +25%. Vertical and horizontal setups are also compensated
Quick setups with the 2-way radio remote control
Electronic Leveling Vibration Filter dampens vibrations typically experienced on tall tripods, in high winds, or on high vibration jobsites
Very rugged with low service costs; takes a 3 ft (1 m) drop on concrete
Mask mode eliminates interference with other crews on the jobsite
Automatic Axis Alignment (GL622N only) is easy to setup for increased accuracy
Radio communication between the laser and HL760 Laserometer allow advanced features and remote display capabilities
Long operating radio range - 490 ft (150 m)
Grade Match displays the existing grade over unknown ground and eliminates time consuming and error prone calculations, time spent searching for grade plans, and over excavating
PlaneLok automatically locks on to an existing elevation or vertical alignment point which eliminates all drift or possibility of error due to improper calibration or weather
5 Year “No Cost” Warranty
General Construction Applications
Leveling concrete forms and footers
General construction vertical alignment and plumb such as anchor bolt and form alignment
“Over the top” sewer and storm drain pipe installations
Driveways and ramps
Grading and excavating
HL760 Applications
Trenching
Remote grade checking with cable free remote display
Wireless monitoring of foundations and steel erections
Risk free monitoring of tilt up wall position
