Topcon RL-H5A Self-Leveling Laser PS.RB Kit with LS-80X Receiver, Rechargeable Batteries, Measuring Rod INCHES and Tripod

The Topcon RL-H5A is a professional-grade self-leveling rotary laser engineered for contractors who demand reliable, high-visibility coverage across large jobsites. Whether you're grading a subdivision lot, setting drainage slopes, or establishing foundation benchmarks, the RL-H5A delivers a consistent 360-degree rotating red beam with automatic leveling that keeps your crew on-grade and on-schedule. This ready-to-work package (model 1035261-01) ships with the LS-80X laser receiver, an inches-calibrated measuring rod, a heavy-duty adjustable tripod, and a rechargeable battery system — everything your team needs for immediate field deployment.

Product Overview & Jobsite Applications

The RL-H5A is purpose-built for outdoor horizontal leveling tasks where a full rotating plane is more practical than a fixed point or line laser. Its high-output red beam and wide operating range make it equally effective on large earthwork projects and confined foundation pours. The LS-80X receiver extends the effective working radius well beyond naked-eye detection, enabling single-operator setups even on open sites. Automatic self-leveling within ±6° of plumb means fast instrument setup with no manual fine-tuning required.

Job Applications

Site Grading & Earthwork: Set cut/fill stakes quickly across large open areas. The LS-80X receiver mounts to the grade rod for one-person operation, reducing the need for a rod person and keeping earthmoving equipment moving.

Drainage & Slope Layout: Use single-axis manual grade mode to establish consistent drainage slopes on parking lots, athletic fields, and agricultural drainage projects without recalculating between setups.

Foundation & Slab Leveling: Verify concrete form heights and slab elevations during pours. The RL-H5A's IP66-rated housing handles the dust and moisture inherent to concrete work without interrupting operations.

Utility & Pipeline Trenching: Maintain consistent invert elevations for sewer, storm drain, and water main installations. The selectable rotation speed allows beam detection even in bright daylight conditions at trench depth.

Frequently Asked Questions

Does the Topcon RL-H5A work in direct sunlight?

Yes. While the red beam may not be visible to the naked eye in bright sunlight, the included LS-80X receiver detects the beam at distances up to 800 meters in full daylight, making outdoor use fully practical without a laser enhancement goggle.

Can the RL-H5A be used for vertical applications or plumb transfer?

The RL-H5A is optimized for horizontal rotating plane applications. It does not natively support 360-degree vertical plane rotation. For vertical layout and plumb transfer, a dedicated pipe laser or dual-axis laser instrument would be more appropriate.

What is the difference between this RS kit and the standard RL-H5A?

The RS kit (model 1035261-01) is a bundled package that includes the LS-80X receiver, an inches-calibrated measuring rod, and a heavy-duty tripod — providing a complete turn-key system versus purchasing the instrument alone. This eliminates the need to source compatible accessories separately.

Is the RL-H5A compatible with machine control systems?

The RL-H5A can interface with basic laser-guided machine control systems that accept a standard rotating laser input via an external sensor. However, for full manufacturer-supported machine control integration, Topcon's dedicated machine control laser models are recommended. Contact Express Tools for guidance on your specific application.
