Features & Benefits

Multiple Applications – the Spectra Precision GL622N 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 – A laser can be affected high vibration or strong wind, especially when the laser is mounted on a tall tripod –both the GL612N, GL622IR,

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.

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.

 

PlaneLok – 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.

Automatic Axis Alignment – A critical factor when working with grade is alignment to the grade hub. If an alignment is off, error can be introduced and exaggerated. The GL622N has an Automatic Axis Alignment function, allowing the user to set-up simply and quickly, maintaining accuracy and eliminating costly errors.

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.

GL622IR Model – This model features an invisible infrared laser beam and is a Class 1 laser, the safest laser classification possible. This type of beam is required in special applications where a visible beam is a safety hazard, distracting or otherwise is not permissible.
