Laser sensor RD300R Digital

RD300R Digital Laser Detector is a modern device for precise laser‑beam detection, ensuring reliability and measurement accuracy at every stage of work.
This detector is designed to work with Nivel System NL series rotary lasers that emit a red beam.
Thanks to its advanced functions, the RD300R Digital Laser Detector performs well in construction, surveying, roadworks, and civil engineering—wherever confidence and speed of execution matter.

Key advantages at a glance

• Wide detection zone: 105 mm – faster beam acquisition and shorter leveling time.
• Adjustable precision: 1 mm / 5 mm / 10 mm – tailored to the task at hand.
• Digital display of height difference – read values without manual calculations.
• Units: mm or inch – convenient metric/imperial switching.
• Displays: 2× LCD + LED – readability up close and from a distance.
• Adjustable audio signals – set the volume to jobsite conditions.
• Rod clamp included – stable, quick mounting.
• IP54 rating – dust resistance and moisture protection.
• Compatibility – Nivel System NL series rotary lasers (red beam).

Wide detection zone and adjustable measurement precision

RD300R Digital Laser Detector offers a 105 mm detection zone, capturing the laser beam faster and streamlining leveling.
Users can choose from three accuracy levels to suit the task:

• • 1 mm – top‑precision work, e.g., installing structures or setting foundation levels,

• 5 mm – standard accuracy for construction and surveying,
• 10 mm – fast terrain leveling where small height differences are acceptable.

Digital height‑difference display

The RD300R Digital detector not only detects the laser beam but also automatically calculates and displays the height difference in millimeters. This means users don’t need manual calculations—the detector immediately indicates the exact deviation from the reference level.

Additionally, you can choose the unit of measure to suit different projects. Users can switch between:

• millimeters (mm) — for maximum precision,
• inches (inch) — for users of the imperial system.

Clear and intuitive displays

For ease of use, the RD300R Digital Laser Detector is equipped with a large, backlit LCD that provides easy reading even in difficult lighting conditions.
There is a second LCD screen on the back—so you can read results comfortably regardless of how the detector is mounted.
An additional LED display enables convenient reading from a greater distance—for example, while working in a machine cab, where the operator can monitor the level without approaching the detector.

Audible signals and secure mounting

Adjustable audible signals indicate the height difference—set the volume to match the noise level on the jobsite.
Mounting to the leveling rod is done with a dedicated bracket included in the set, ensuring stability and precise readings without the risk of accidental movement.

Resistance to harsh conditions

The RD300R Digital Laser Detector is designed for demanding field work. The IP54 ingress‑protection rating means reliability in rain, high dust levels, and intensive use.

• Water resistance — protection against rain and moisture,
• Dust and dirt resistance — dependable operation in construction environments,
• Durable housing — resistant to impacts and frequent use.
