Topcon RL-H5A Self-Leveling Laser PS.DB2 Kit with LS-80X Receiver, Measuring Rod INCHES and Tripod - 1021200-49-K2 (RECHARGEABLE)

The Topcon RL-H5A (model 1021200-49-K2) is a construction-grade self-leveling rotary laser built for demanding jobsite conditions. Whether you're grading a foundation, establishing floor elevations, or setting drainage slopes, the RL-H5A delivers consistent, reliable horizontal reference planes across a full 360-degree radius. This complete kit includes the LS-80X digital grade rod receiver, an aluminum tripod, an inch-graduated measuring rod, and a rechargeable battery system — everything a professional crew needs to get to work out of the box.

Overview & Jobsite Applications

Designed specifically for general construction workflows, the RL-H5A combines Topcon's proven self-leveling pendulum system with a rugged IP66-rated housing that shrugs off dust, rain, and the daily abuse of busy job sites. It self-levels within ±5 degrees in seconds and locks the pendulum automatically when moved, protecting the internal mechanism during transport. Operating at up to 2,600 ft (800 m) in diameter with the included LS-80X receiver, this laser handles everything from residential grading to commercial slab work with ease.

Job Applications

Foundation & Slab Layout: Establish precise horizontal planes for concrete pours and footing elevations. The RL-H5A's ±1/16 in accuracy at 100 ft keeps your forms true from corner to corner.

Site Grading & Excavation: Use the high-visibility receiver and long working range to control cut-and-fill operations across large sites without repositioning the instrument.

Interior Finish Work: Drop ceiling grids, suspended mechanical systems, and partition walls all benefit from a consistent laser reference — the selectable slow rotation mode (300 RPM) gives receivers a stronger, more readable signal indoors.

Drainage & Utility Trenching: Confirm pipe fall and drainage grades quickly. The LS-80X receiver reads above-grade, saving time versus manual measurement at every stake.

Frequently Asked Questions

Does the Topcon RL-H5A work outdoors in bright sunlight?

Yes. While the red laser beam itself is difficult to see with the naked eye outdoors, the included LS-80X receiver detects the beam up to 1,300 ft away in full sunlight, making the RL-H5A fully practical for exterior grading and site work.

Can the RL-H5A be used for slope or grade applications?

The RL-H5A is a horizontal-only self-leveling laser and does not have a manual slope mode. For grade matching or dual-axis slope applications, consider the Topcon RL-H5B or RL-200 series. The RL-H5A excels at establishing true horizontal planes.

How long does the rechargeable battery last on a single charge?

Topcon rates the RL-H5A at up to 60 hours of continuous operation on the included rechargeable battery pack under normal operating conditions. Cold temperatures may reduce runtime; the kit includes an AC charger and the instrument also accepts optional alkaline battery packs.

Is the RL-H5A compatible with Topcon machine control systems?

The RL-H5A is primarily a grade-and-layout instrument rather than a machine control laser. For dozer or motor grader control integration, Topcon's RL-200 or 3D-MC systems are the appropriate platforms. However, the RL-H5A pairs well with grade checkers and manual layout crews on mixed-equipment job sites.
