PRODUCT OVERVIEW

Product Description

The Spectra Precision GL622IR is a professional dual-slope infrared grade laser engineered for contractors who need reliable grade control in high-ambient-light conditions where a standard red beam laser falls short. Pairing invisible infrared laser technology with the precision of independent dual-axis slope control, the GL622IR delivers consistent, accurate results on demanding grading, drainage, and site work projects.

Product Overview & Jobsite Applications

Unlike visible red beam lasers that struggle in bright sunlight, the GL622IR transmits an infrared signal detected exclusively by the included HL760 receiver, making it effective outdoors at extended ranges regardless of lighting conditions. The RC602N remote control allows operators to adjust slope values and monitor laser status wirelessly from any point on the site, eliminating repeated trips back to the instrument. Whether you are establishing a single-plane grade, setting dual-axis fall on a parking lot, or dialing in swales for drainage work, the GL622IR handles the task with repeatable, survey-grade accuracy.

Job Applications

Parking Lots & Flatwork: Set independent X and Y slopes simultaneously to achieve proper drainage fall across large concrete or asphalt pours — no secondary setups required.

Site Grading & Earthwork: Control motor graders and scrapers with the extended 600 m working range; the infrared signal remains stable in full sun where visible lasers wash out.

Drainage & Swale Work: Program precise low-percentage grades down to 0.001% for culverts, retention areas, and agricultural drainage channels that demand exact slope tolerances.

Foundation & Slab Prep: Establish consistent elevation references across large slab areas using the HL760 receiver on a grade rod, speeding up formwork and subbase verification.

Compatible Accessories

Frequently Asked Questions

Can the GL622IR be used with machine control systems?: The GL622IR is primarily a rotating grade laser designed for manual grade rod and receiver use. For full machine control integration, Spectra Precision offers dedicated machine control lasers; however, the GL622IR's infrared signal is compatible with many aftermarket machine control receivers — consult your dealer for compatibility details.
What is the difference between the GL622IR and the standard GL622?: The GL622 uses a visible red beam, while the GL622IR emits an invisible infrared signal. The infrared version is preferred for outdoor, high-ambient-light applications where the red beam is difficult for the receiver to lock onto at long range. Both models share the same dual-slope capability and operating range.
How far away can the RC602N remote control the laser?: The RC602N wireless remote operates at ranges up to approximately 200 m (650 ft) line-of-sight, allowing grade operators to adjust slope percentages, change rotation speed, and power the unit on or off without walking back to the laser.
Is the GL622IR covered by a warranty?: Spectra Precision backs the GL622IR with a standard limited warranty covering defects in materials and workmanship. Express Tools is an authorized dealer, so your unit is fully eligible for factory warranty service. Contact us for current warranty terms and repair service options.

Why This Equipment

Dual Grade Control

Control two slopes simultaneously for crowns, swales, and complex drainage layouts.

Machine Ready

Pairs with machine receivers for dozer, grader, and scraper grade control.

IP67 Rated

Weatherproof for outdoor use in rain, dust, and construction site conditions.

High Accuracy

±0.1mm/m grade accuracy — holds tolerance through a full working day.

Why Buy This?

Continuous grade control. No continuous labor.

Grade stakers cost $50–80/hr and disappear between passes. A dual-slope grade laser installs once and controls your blade automatically — through every cut, every fill, every pass. That's the math that makes grade lasers one of the fastest ROI investments in earthwork.

Professional contractors specify dual-grade systems for a reason: single-grade units work for straight drainage. The moment a job has a crown, a swale, or a complex parking lot slope — you need dual-grade.

Buying from Express Tools means authorized, factory-fresh inventory, legitimate firmware, and technical knowledge when you need it.
