JOHNSON JRT300-RDHV-K Red Dual Slope Rotary Laser Kit
The JOHNSON JRT300-RDHV-K is a red dual-slope rotary laser kit designed for large jobsite layout and grading tasks. It provides full 360° coverage and dual-axis slope control to set and maintain precise grades across broad areas.
This unit supports exterior use with a detector for extended range and one-person operation. It offers five selectable rotation speeds, four angle scan modes, visual and audible alarms, and an included remote and detector to improve on-site productivity.
Built for harsh environments, the instrument carries an IP67 rating and impact resistance to 6' (2 m). It runs on lithium-ion rechargeable batteries and ships as a kit with batteries, charger, remote, detector and a hard-shell carrying case for transit and storage.
Electronic self-leveling and dual-slope capability allow slope settings up to ±5° on both axes, while the laser and detector combination extends jobsite coverage up to a 4,000' diameter when used outdoors.
Key specifications
- Exterior Range: Up to 4,000' diameter with detector (included)
- Slope: ±5° Dual
- Laser Accuracy: +1/16"/100'
- Battery Life: 21 hours
- Dual-slope electronic leveling – Performs slopes up to ±5° in both X and Y axes for complex grade and drainage layouts.
- Long exterior range with detector – Up to 4,000' diameter coverage when used with the included detector for large sites.
- IP67 environmental protection – Sealed construction helps protect the instrument in harsh jobsite conditions.
- Impact resistant to 6' (2 m) – Designed to withstand accidental tips and drops common on active worksites.
- Multiple rotation speeds – Five speed settings (0, 100, 300, 600, 1200 RPM) let you match beam visibility and detection needs.
- 400' remote range and detector – Remote control and detector support one-person operation and extended control from a distance.
- Long runtime lithium-ion batteries – Rechargeable lithium-ion power provides all-day runtime capacity as listed in specifications.
- Four angle scan modes – Selectable scan angles (0°, 15°, 30°, 60°) for focused or broad coverage patterns.
- Visual and audible alarms – Alerts indicate when the unit is in or beyond the leveling range to aid setup and accuracy.
- High laser accuracy – Specified laser accuracy of +1/16" per 100' supports precise elevation and layout work.
