The Nivel System NL640R optical builder is a durable and precise tool designed for large construction projects, both indoors and outdoors (with sensor). It allows working with a 360° horizontal plane (including digital tilts) and a vertical plane, providing an efficient solution for leveling, marking, and slope control.

• Extensive measurements – operational range of 600 m (diameter) with sensor.
• High accuracy – ±0.72 mm/10 m.
• Digital tilts on 2 axes – ±10% adjustment (X and Y), suitable for drainage, ramps, roads, foundations, etc.
• Electronic stabilizer – stable and accurate leveling even under vibration conditions.
• User-friendly operation – clear menu + remote control.
• Durable construction – sealed and robust housing, IP65 protection class, metal head.
• Efficient power supply – Li-ion battery 3.7V / 8000 mAh.

After startup, the laser self-levels and is ready for immediate use. The projected beam creates a reference for horizontal or vertical work. Along with the sensor and pole, it allows for precise leveling performed by a single operator.
