Topcon RL-SV2S Self-Leveling Dual Grade Laser RB Kit with LS-100D Receiver and Rechargeable Batteries

Topcon RL-SV2S — Professional Dual Grade Rotary Laser for Demanding Job Sites

The Topcon RL-SV2S RB Kit delivers the precision and reliability that grading crews, concrete finishers, and site contractors demand on complex dual-slope projects. Built and calibrated in Japan to Topcon's exacting standards, this kit pairs the RL-SV2S rotary laser with the LS-100D laser receiver and rechargeable battery system — giving your crew everything needed for a full day of uninterrupted, high-accuracy grading work right out of the box.

Dual Grade Laser Built for Complex Site Work

Managing two independent slopes simultaneously is no simple task, and the RL-SV2S is purpose-built for exactly that challenge. Whether you're establishing cross-fall on a parking lot, setting drainage grades across a retention pond, or fine-grading a road crown, the RL-SV2S delivers independent X and Y axis grade control with a wide slope range that covers virtually every civil and commercial grading scenario. The self-leveling design automatically compensates for minor setup variations, so your crew spends less time checking the instrument and more time moving material.

What's Included in the RL-SV2S RB Kit

• Topcon RL-SV2S Dual Grade Rotary Laser — the core instrument with dual-axis grade capability
• LS-100D Laser Receiver — wide-range detector with digital and audio grade indication, compatible with machine control rod
• Rechargeable Battery Pack (RB) — eliminates AA battery cost and downtime on long grading shifts
• Battery Charger — standard charger for the included rechargeable pack
• Carrying Case — durable molded case for transport and storage
• Alignment Sight — for quick, accurate instrument orientation on setup
• Tripod Attachment Adapter — 5/8" x 11 thread compatible

Job Site Applications

Parking Lot & Commercial Flatwork: Set dual cross-slopes across large concrete or asphalt pours and maintain consistent grade without multiple setups. The RL-SV2S holds both axes simultaneously so finishing crews stay productive across the entire slab.

Site Grading & Drainage: Establish positive drainage grades over retention areas, detention basins, and stormwater channels where a single flat plane simply won't work. Independent X/Y control makes compound slope work straightforward.

Road Crown & Subgrade Prep: Set crown grades on roadway subbase preparation. The wide operating range means a single instrument setup covers long stretches of roadway without repositioning.

Agricultural & Land Leveling: Slope fields for surface irrigation efficiency. The extended battery runtime and rugged IP66 housing keep the RL-SV2S running through long field days in dusty, wet conditions.

Frequently Asked Questions

Does the RL-SV2S work with machine control grade rods?

Yes. The included LS-100D receiver is compatible with standard grade rods used in machine control and manual grading applications, making it versatile across both hand-grade and equipment-mounted setups.

What is the difference between the RB and standard RL-SV2S kit?

The RB designation indicates the kit includes a rechargeable battery pack instead of standard alkaline batteries. This reduces long-term operating cost and is ideal for crews running the instrument across full work days without access to battery resupply.

Can the RL-SV2S be used in rain or dusty conditions?

Yes. The RL-SV2S carries an IP66 rating, meaning it is fully protected against dust ingress and resistant to powerful water jets. It is designed for active outdoor construction environments in variable weather.

What is the maximum slope the RL-SV2S can project?

The RL-SV2S supports a grade range of ±10% (±5.7°) on both the X and Y axes independently, which covers the vast majority of civil grading, drainage, and site preparation applications.
