Spectra Precision GL622N Dual-Slope Grade Laser
The GL622N dual-slope grade laser comes with HL760 receiver, C70 rod clamp, RC602N remote, 105516 Vertical Adapter for HL Receiver, 10 Ah NIMH Batteries and Charger. It is an easy-to-use, 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.
Features & Benefits:
• It 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.
• Long Range – one person elevation and grade control with 800 m (2,600 ft) diameter range increases productivity
• Automatic self-levelling – 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)
• Grade Range – Large, fully compensated grade range from -25% to 25%, keeping the laser levelled no matter what grade you need, reducing errors and improving productivity
• Anti-Vibration Filter that can be set according to the conditions allowing work to continue regardless of wind conditions or excessive vibrations
• Rugged – Can withstand a 1m (3 feet) drop directly onto concrete or 1.5m (5 feet) pushover on tripod
• The PlaneLok function can be activated, keeping 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
• It has an Automatic Axis Alignment function, allowing simple set-up simply, maintaining accuracy and eliminating costly errors
• Mask Mode 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
