This new Spectra model GL622IR 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 red beam is a safety hazard, distracting or otherwise is not permissible.  There are certain railway and mining applications where this is required.

The GL622IR package includes the RC602N full-function remote control. Both the remote and the laser have a large, backlit, intuitive graphic displays and keypads that make setups easier and faster than ever.  With the remote, contractors can do everything that they can do at the laser keypad, up to 500 feet away.  The ability to make grade changes and start automatic alignments remotely can significantly reduce setup time and speed up operations.

This laser offers automatic self-leveling in grade, horizontal and vertical planes.  Both feature  grade capability of ± 25% and  can be used in a wide variety of grading, excavating and alignment applications by general and specialty contractors.

The GL622IR is a dual slope grade laser. This rugged, automatic self-leveling laser has a grade capability of ± 25% and can be used in a wide variety of grading, excavating and alignment applications by general and specialty contractors.

Each laser system includes the advanced HL760 Digital Receiver that provides a digital readout of elevation and can be used at an operating diameter of up to 2,600 feet.  With the HL760

With the HL760 everal advanced features of the GL622IR series can be utilized:

Grade Match:  Wireless communication between the HL760 Digital Receiver  and the transmitter provide automatic Grade Matching which allows measurement of unknown grade values between two points.

Plane-Lok: For applications that require maximum stability and accuracy, PlaneLok is available in both the horizontal and vertical planes. PlaneLok automatically locks the beam on the receiver and keeps it on grade, reducing typical environmental factors that may induce an error.

Automatic Axis Alignment (GL622N  only): Automatic axes alignments can be accomplished by positioning the receiver at the direction hub in a range of +/-40° at the desired laser axis. This allows contractors to easily perform dual axis alignments for grade work applications such as sports fields,  parking lots, tennis courts, driveways or any irregular field with non-perpendicular grade profiles

In addition, the HL760 Digital Receiver  can communicate  with another HL760 for long-range wireless remote display and monitoring.

The GL622N Grade Lasers self-plumb in the vertical position to allow an even wider range of applications such as such as anchor bolt installation, form, tilt up, and curtain wall plumbing.

With its rugged design,  the GL622N  lasers can survive a drop of up to 3-feet on concrete. The lasers also feature IP67 moisture and dust sealing to handle the tough construction environments.

All the features and benefits of the GL622N laser are incorporated into the GL622IR laser with the exception of vertical leveling.  The 5-year warranty and 3-foot drop specification will ensure a long productive life.
