Spectra Precision® GL622N Grade Laser — The Easy-To-Use, Full Featured Automatic Grade Laser.
The GL622N Dual Grade Laser is a rugged, automatic self-leveling laser 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.
This laser comes with a radio remote control that provides fully functional capabilities up to 150 m (490 ft) 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 HL760 Digital Readout Receiver that can be used at an operating diameter of up to 800 m (2,600 ft).
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 HL760 can be paired with another HL760 turning the second receiver into a remote display that could allow a machine operator to see what the rod-man is seeing when dipping for levels.
The GL622N is self-leveling 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 GL622N can withstand a 1 m (3 ft).

Multiple Applications: Spectra Precision GL622N provides the ability to control level, alignment, single grade /dual grade and set 90 degrees
Automatic Self-Levelling: Provides fast, easy set-up for horizontal level, grade or vertical alignment
Automatic Grade Matching: Laser moves to the on-grade position on the receiver automatically by communicating wirelessly with 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)
Grade Range: Large, fully compensated grade range from -25% to 25% - keeping the laser leveled no matter what grade you need reducing errors and improving productivity
Anti-Vibration Filter: A laser can be affected high vibration or strong wind, especially when the laser is mounted on a tall tripod – G622N has an anti-vibration filter that can be set according to the conditions allowing work to continue regardless of wind conditions or excessive vibrations
Temperature Compensation & PlaneLok: As temperature fluctuates throughout the working day, the internal components of a laser can expand and contract which can cause some additional error without the user noticing
This is can firstly be resolved through the automatic temperature check that the laser performs where the internal software calibrates the laser to its optimal performance based on the temperature
This keeps the laser beam fixed to a receiver in a set a position eliminating any error that can be caused by fluctuating temperatures, keeping the laser accurate and error free
Additionally the PlaneLok function can be activated
Automatic Axis Alignment: Allows the user to set-up simply and quickly, maintaining accuracy and eliminating costly errors
Rugged: The GL622N can withstand a 1 m (3 ft) drop directly onto concrete or 1.5 m (5 ft) pushover on tripod, eliminating costly repairs
Mask Mode: The GL622N has a virtual masking function that allows the laser beam to be turned off in up to 3 sides, avoiding false reading from glass reflections or interfering with other lasers on the same jobsite
