Spectra Precision Dual-Slope Grade Laser Level Kit with Laser Meter, C70 Rod Clamp, Remote Control, 10 Ah NiMH Batteries, Charger - GL622N

The Spectra Precision GL622N pro Laser Level measure tool kit comes with a HL760 Laser meter, C70 rod clamp, RC602 remote control, and is rechargeable with its 10 Ah NiMH batteries and a charger. This rugged, self-leveling laser device features grade capability of 25% and can be used in a wide variety of grading, excavating, and alignment construction and welding applications. The RC602 full-function radio remote control, which offers advanced digital features like Grade Match, Plane Lok and Automatic Axis Alignment, has an intuitive graphic display, as well as the transmitters, which has back lighting for ease of viewing. Contractors can do everything with the remote control that they can do at the laser keypad, up to a distance of 100m (330 ft) away - even from the cab of a machine. The ability to make grade changes remotely can significantly reduce setup time and speed operations. The GL622N can also self-plumb in the vertical position to allow an even wider range of applications such as anchor bolt installation, form, tilt up, and curtain wall plumbing. With its rugged design, the GL622N Grade Laser can survive a drop of up to 1 meter (3 feet) on concrete. The laser also features IP67 moisture and dust sealing to handle the tough outdoor construction environment. Let’s get it straight – the Spectra Precision GL622N is the best laser leveler tool you’ll find – bottom line!

Features

Maintenance Tips

• Clean Regularly: Wipe the laser housing, receiver sensor, and glass aperture with a soft damp cloth. Avoid harsh chemicals or solvents to protect optical components.

• Protect the Laser Lens: Remove dust, mud, or water from optical parts immediately, as debris can reduce beam quality and operating range.

• Maintain Batteries Properly: Charge the 10Ah NiMH battery pack only with the supplied charger and store batteries in a cool, dry place when not in use.

• Store in the Carrying Case: Always place the unit, remote, and receiver in the protective case after use to prevent dust, moisture, and impact damage.

• Avoid Extreme Temperatures: Do not leave the laser in vehicles or environments with rapid temperature changes, which can affect accuracy and electronics.

• Check Calibration Frequently: Verify leveling accuracy after drops, heavy use, or long storage to ensure precise grading results.

• Use Stable Mounting: Set the laser on a secure tripod and firm surface to maintain accuracy during operation.
