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. 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.Īnti-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, GL622IR,Īnd 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. Long Range – one person elevation and grade control with 800 m (2,600 ft) diameter range increases productivityĪutomatic self-levelling – provides fast, easy set-up for horizontal level, grade or vertical alignment (vertical on GL622N only)Īutomatic 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) The GL622IR is not used for vertical alignment or 90 degree layout.
Multiple Applications – the Spectra Precision GL622N provides the ability to control level, alignment, dual grade and set 90 degrees.
