Spectra Precision 541546 GL622N Automatic Self-Leveling Dual Grade Laser Level Kit

Spectra Precision GL622N Dual Grade Laser Level (Part No. 541546) – With HL760 Receiver, RC602N Remote & Rechargeable Battery Kit

The Spectra Precision GL622N Automatic Dual Grade Laser Level is a high-accuracy, fully programmable grade laser engineered for demanding commercial and industrial grade applications. Designed for versatility, it delivers precision leveling, grade control, and vertical alignment with grade capability from -25% to +25% on both axes (independently). The GL622N is built to take on concrete work, site prep, grading, trenching, and vertical alignment, all with minimal setup time and maximum durability. The laser includes the RC602N wireless remote, HL760 digital receiver, NiMH rechargeable battery pack, and hard-shell carrying case, giving professionals everything needed to get to work immediately.

With self-leveling, automatic axis alignment, Grade Match, and PlaneLok functions, this tool eliminates guesswork, reduces setup errors, and boosts productivity on complex jobsites. The HL760 Laserometer allows for cable-free grade checking and wireless monitoring from up to 150 metres away. Its Electronic Leveling Vibration Filter minimizes false errors due to wind or heavy equipment movement, making it suitable for jobsites with high vibration or unstable ground. The GL622N has been tested to survive a 1-metre drop on concrete, giving contractors a tough, low-maintenance tool they can rely on daily. Built with IP67-rated sealing, it stands up to rain, dust, and jobsite grime.

Built for professionals working in real-world conditions! The GL622N isn’t just a laser—it’s a jobsite workhorse that reduces the time and labour it takes to get grades set, trenches cut, and vertical control established. Excavators can cut more accurately with less rework, and concrete crews can set forms and footers with confidence in the readings. The RC602N two-way remote allows setup from inside the cab or on the other side of the site, while digital elevation readouts from the HL760 prevent errors and keep crews productive. Trades working in infrastructure, roadwork, underground utilities, and foundation layout will see cost and time savings from fewer passes, faster grade matching, and better jobsite coordination.

The GL622IR is a Class 1 laser. This type of laser beam is required in special applications where a visible beam is a safety hazard, distracting or otherwise is not allowed.

Spectra Precision 541546 GL622N Automatic Self-Leveling Dual Grade Laser Level Features

• GL622N Versatile Automatic Single and Dual Grade Laser for Level, Grade, and Vertical Alignment
