PRODUCT OVERVIEW

Product Description

The Topcon RL-HV1S Dual-Slope Laser Kit (Model 1051612-09) is a complete, rechargeable grade laser system engineered for contractors who demand accuracy on complex slope and grading work. Paired with the LS-100D digital receiver and rechargeable battery system, this kit eliminates guesswork on critical elevation and slope applications — delivering repeatable, verified results from the first setup to final inspection. Whether you are grading a parking lot, designing a drainage swale, or finishing a road subbase, the RL-HV1S provides the precision and range to get the job done right.

Built for Demanding Jobsite Conditions

Designed for road construction, site development, concrete flatwork, and drainage design, the RL-HV1S handles the full range of grade work encountered by civil and general contractors. Its dual-slope capability allows simultaneous X and Y axis slope settings, making it uniquely suited for crowned roadways, athletic fields with complex drainage requirements, and parking structures where cross-slopes must meet strict ADA and engineering specifications. The self-leveling design speeds setup and eliminates operator-induced errors on uneven terrain.

Job Applications

Road Construction & Subbase Grading: Set precise crown slopes and cross-falls across wide roadway corridors without moving the instrument. The 600m range covers multi-lane road sections in a single setup.
Site Drainage & Swale Design: Use dual-slope mode to establish compound drainage gradients that direct water flow accurately to catch basins and detention areas — critical for meeting civil drainage specifications.
Concrete Flatwork & Slab Placement: Maintain consistent grade during pour operations. The LS-100D receiver provides clear above/below/on-grade readouts that screed operators can act on immediately.
Athletic Fields & Parking Lots: Achieve compliant cross-slopes and ADA-conforming grades across large flat areas where elevation errors are difficult to detect visually but fail inspection.

Compatible Accessories

Topcon LS-100D Replacement Receiver — Digital grade receiver with audible and visual on-grade indicators
Topcon RD-1 Remote Control — Wireless slope adjustment and rotation speed control from the rod
Topcon Aluminum Grade Rod — Graduated rod compatible with LS-100D receiver clamp
Topcon Heavy-Duty Tripod — Stable platform for rotating laser setups on soft or uneven ground
Replacement Rechargeable Battery Pack — Extended run-time backup power for full-day operations

Frequently Asked Questions

Can the RL-HV1S set slope on both axes at the same time?: Yes. The RL-HV1S supports true dual-slope operation, allowing you to set independent grade percentages on both the X and Y axes simultaneously. This is essential for crowned roads, athletic fields, and any surface requiring compound slopes.
What is the effective working range of this laser kit?: With the included LS-100D receiver, the RL-HV1S has an operating diameter of up to 600 meters (approximately 1,970 feet). Actual range may vary slightly based on sunlight conditions and receiver positioning.
How long does the rechargeable battery last on a full charge?: The included rechargeable battery pack provides up to 60 hours of continuous operation, making it suitable for multi-day use between charges on active job sites.
Is the RL-HV1S protected against dust and water on the jobsite?: Yes. The RL-HV1S carries an IP66 ingress protection rating, meaning it is fully protected against dust and resistant to powerful water jets. It is designed to operate reliably in wet and dusty construction environments.

Why This Equipment

Dual Grade Control

Control two slopes simultaneously for crowns, swales, and complex drainage layouts.

Machine Ready

Pairs with machine receivers for dozer, grader, and scraper grade control.

IP67 Rated

Weatherproof for outdoor use in rain, dust, and construction site conditions.

High Accuracy

±0.1mm/m grade accuracy — holds tolerance through a full working day.

Why Buy This?

Continuous grade control. No continuous labor.

Grade stakers cost $50–80/hr and disappear between passes. A dual-slope grade laser installs once and controls your blade automatically — through every cut, every fill, every pass. That's the math that makes grade lasers one of the fastest ROI investments in earthwork.

Professional contractors specify dual-grade systems for a reason: single-grade units work for straight drainage. The moment a job has a crown, a swale, or a complex parking lot slope — you need dual-grade.

Buying from Express Tools means authorized, factory-fresh inventory, legitimate firmware, and technical knowledge when you need it.
