Perfect for indoor and outdoor applications, the Spectra GL622IR Infrared Dual Grade Laser is an electronic self-leveling laser that offers an accuracy of ±1/16 inch at 100 feet and a dual grade range of ±25%. This Spectra grade laser comes with the advanced HL760 digital receiver which operates at a diameter range of 2,600 feet. With the HL760, this grade laser can also perform applications such as Grade Match, PlaneLok, and Automatic Axis Alignment.

The Spectra GL622IR grade laser uses an invisible Class 1 infrared laser beam that is perfect for general construction, railway jobs, mining tasks, and other special applications where a visible beam is not safe to use. With an optional RC602N remote control, the GL622IR allows contractors to make grade changes and begin mechanical alignments remotely up to 490 feet away. This Spectra dual grade laser also performs quick setups for horizontal and grade tasks.

The GL622IR infrared grade laser features a large backlit, graphics LCD display and keypads that allow construction professionals to perform a hassle-free operation. With an IP67 rating, this construction laser can also withstand drop up to three feet. In addition, it uses rechargeable NiMH batteries that power the instrument up to 40 hours which makes the GL622IR a good companion for long hours of work.
