Topcon RL-H5A Self-Leveling Laser PS.RB Kit with LS-80X Receiver and Rechargeable Batteries

The Topcon RL-H5A Rechargeable Rotary Laser System (RS Package, 1021200-49) is engineered for contractors who run multi-day, full-shift operations where battery cost and downtime matter. Pairing the field-proven RL-H5A laser with a rechargeable battery set, field charger, and the long-range LS-80X receiver, this kit eliminates the hidden cost of disposable batteries across concrete pours, mass grading, and extended site prep schedules.

System Overview & Jobsite Applications

Designed for horizontal leveling tasks across large sites, the RL-H5A delivers a self-leveling, 360-degree rotating laser beam with a working range of up to 800 meters in diameter when used with the included LS-80X receiver. The IP-66 rated housing on both the laser and receiver stands up to dust, rain, and the general abuse of active jobsites. The rechargeable battery system is specifically designed for operations that run continuous shifts — paving crews, grading and earthwork crews, and concrete flatwork teams will find the cost savings compound quickly versus alkaline replacements on week-long or multi-week projects.

Job Applications

Mass Grading & Earthwork: The 800m working diameter and LS-80X receiver's high-visibility display let grade checkers work far from the instrument — ideal when dozers and motor graders are making long passes across large pads.

Concrete Flatwork & Pours: Consistent horizontal reference across the entire pour area with no battery changes mid-shift. The rechargeable pack supports full-day pours without interruption.

Site Preparation & Drainage Work: Quickly establish benchmark elevations for drainage swales, parking lot grades, and subbase prep with repeatable ±10 arc-second accuracy.

Foundation Layout & Footing Checks: Use the LS-80X receiver on a grade rod to verify footing depths and slab elevations across residential and commercial foundation work.

Frequently Asked Questions

What is the difference between the RL-H5A standard package and the RS rechargeable package?

The RS (Rechargeable System) package substitutes the standard AA alkaline battery holder for a dedicated rechargeable battery pack and field charger. The laser itself is identical — the RS kit is designed for contractors doing extended operations where recharging between shifts is more economical than purchasing AA batteries continuously.

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

At the lowest rotation speed setting (300 RPM), the rechargeable pack delivers up to approximately 100 hours of run time. At higher rotation speeds, expect reduced battery life. Most full-shift grading operations will see multiple days of use per charge under normal conditions.

Is the LS-80X receiver included in this kit?

Yes. The Topcon RL-H5A RS 1021200-49 package includes the LS-80X long-range receiver with rod clamp. The LS-80X features an 80mm detection window and IP-66 sealing, and is compatible with other Topcon RL-series lasers as a standalone replacement unit as well.

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

The RL-H5A is designed primarily for horizontal leveling applications. It self-levels in the horizontal plane only. For vertical plane work or dual-axis slope applications, Topcon's RL-SV2S or similar dual-axis models would be more appropriate. Consult your Express Tools rep if you need guidance on the right tool for sloped or multi-plane work.
