Spectra Precision GL622N Grade Laser

Model Number: GL622N

Features:

Provides the ability to control level, alignment, dual grade and set 90 degrees. The GL622IR is not used for vertical alignment or 90 degree layout.
One person elevation and grade control with 800 m (2,600 ft) diameter range increases productivity
Provides fast, easy set-up for horizontal level, grade or vertical alignment (vertical on GL622N only)
Automatic Grade Matching – meaning the 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)
Anti-Vibration Filter – A laser can be affected high vibration or strong wind, especially when the laser is mounted on a tall tripod –both the GL612N and G622N have 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
The GL622N has an Automatic Axis Alignment function, allowing the user to set-up simply and quickly, maintaining accuracy and eliminating costly errors.
Rugged – the GL622N and GL622IR can withstand a 1m (3 feet) drop directly onto concrete or 1.5m (5 feet) pushover on tripod, eliminating costly repairs.
Mask Mode – the lasers have 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.
The GL622N Dual Grade Laser is rugged, automatic self-levelling 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 specialty contractors.
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.
Quickly adapts to site requirements
Simplifies level, grade and alignment setups
Reduces time to do steep slope work and drainage installation
Increases reliability, accuracy and durability
Economize operating costs
