ONSTRUCTION LASER INSTRUMENTS sOkkia 1 Dual-Grade Laser When Reliability Matters, SDG1 is the Right Answer. Advanced Technology for Unsurpassed Reliability The SDG1 controls the tilt of the rotating axis by constantly monitoring its inclination with a revolutionary encoding system. This unique technology makes it possible to maintain an accurate laser plane despite variations in environmental factors such as wind, vibration, temperature and direct sunlight. Leveling repeatability is the highest in the industry: 5 arc seconds. Wide Grade and Working Range The SDG1 creates a dual-grade plane ranging from -10% to +10% in the X axis and from -5% to +25% in the Y axis. In combination with the LR200 standard detector, the SDG1 provides a working range of 800 m (2,620 ft.) in diameter.
