The Topcon RL-HV2S is a professional-grade, self-leveling rotary laser designed for contractors who demand precision in both horizontal and vertical plane applications. This bare-unit configuration is ideal for established operations that already maintain compatible receivers, battery packs, and tripod or grade rod mounting systems — eliminating the cost of redundant accessories and delivering maximum value for teams integrating advanced laser technology into existing grade control workflows.
Overview & Jobsite Applications
Built to Topcon's exacting standards, the RL-HV2S delivers reliable dual-axis performance across a wide range of commercial, civil, and residential construction environments. Whether you're setting floor elevations, plumbing walls, or managing rough grading operations, the RL-HV2S provides a stable, high-visibility reference plane at working radii suited to large open jobsites. Its rugged housing and sealed construction hold up in dusty, wet, and vibration-prone environments — exactly the conditions contractors face every day.
Key Specifications
- Operation Modes: Horizontal and vertical dual-plane rotation
- Self-Leveling Range: ±5° automatic self-leveling
- Accuracy: ±1mm at 10m (±3/32 in. at 30 ft.)
- Working Radius: Up to 800m diameter (with compatible receiver)
- Rotation Speed: 300, 600, or 1000 RPM selectable
- Grade Setting Range: Manual grade capability via fine-tune adjustment
- IP Rating: IP66 dust and water resistant
- Power: Compatible with Topcon rechargeable battery system (not included)
- Configuration: Bare unit — receiver, battery, and tripod sold separately
Key Features
- Dual-Plane Operation: Simultaneous horizontal and vertical beam output for expanded layout and grading capability from a single instrument setup
- Automatic Self-Leveling: Compensator engages within ±5° of level, reducing setup time and operator error on uneven terrain
- Variable Rotation Speed: Three selectable RPM settings allow optimization for visibility range versus beam detection speed at the receiver
- Remote Control Ready: Compatible with Topcon remote control accessories for solo operation across large sites
- Rugged Sealed Housing: IP66-rated construction resists dust ingress and direct water exposure for all-weather reliability
- Out-of-Level Alert: Automatic shutdown and alert when instrument is disturbed beyond self-leveling range, protecting measurement integrity
Job Applications
Site Grading & Earthwork: Establish a consistent horizontal reference plane across large excavation and grading sites, enabling machine operators and grade checkers to maintain elevation control efficiently without constant instrument repositioning.
Concrete Flatwork & Floor Leveling: Set precise elevation benchmarks for slab-on-grade pours, post-tension decks, and elevated concrete floors where tight tolerance flatness specifications must be met.
Interior Layout & Plumb Transfer: Switch to vertical plane mode to project plumb reference lines for stud wall layout, curtain wall alignment, column plumbing, and elevator shaft control on multi-story commercial projects.
Utility & Pipeline Grade Control: Provide a consistent slope reference for storm drain, sanitary sewer, and utility trench work where maintaining accurate fall-per-foot over long runs is critical to system performance and code compliance.

Frequently Asked Questions
- What is included with the Topcon RL-HV2S bare unit?
- The RL-HV2S bare unit includes the laser instrument only. Receiver, battery pack, charger, remote control, tripod, and carrying case are not included. This configuration is intended for contractors who already own compatible Topcon accessories or who wish to select accessories separately.
- Is the RL-HV2S compatible with my existing Topcon receiver?
- The RL-HV2S is compatible with Topcon's current line of laser receivers, including the LS-80L and similar models. We recommend confirming compatibility with your specific receiver model before purchase. Contact our team for guidance.
- Can the RL-HV2S operate in both horizontal and vertical modes simultaneously?
- Yes. The RL-HV2S is engineered for dual-plane operation, allowing both the horizontal and vertical reference beams to be active at the same time. This is particularly useful for complex layout tasks where both elevation and plumb references are needed from a single instrument position.
- What is the working range of the RL-HV2S?
- With a compatible laser receiver, the RL-HV2S delivers a working radius of up to 400 meters (800 meters diameter), making it well-suited for large open jobsites including civil grading, airfield work, and commercial site development.
