Features & Benefits 1. Wide range of applications GL622N: Supports leveling, alignment, dual slope and 90 degree alignment. GL622IR: No vertical alignment or 90 degree option. 2. Long range One-person operation up to 800m range for height and slope control. 3. Automatic self-leveling Quick and easy for horizontal and vertical leveling (GL622N only). 4. Automatic slope measurement Wireless communication with the receiver for automatic slope adjustment and calculation (ideal for constant but unknown slopes). 5. Wide slope range Fully compensated range from -25% to 25% for reduced errors and increased productivity. 6. Anti-vibration filter Protection against strong vibrations and wind, especially when mounted high (available for GL612N, GL622IR and GL622N). 7. Ruggedness Withstands 1m drops onto concrete and 1.5m from tripod. 8. PlaneLok Locks the laser beam in the center position of the receiver to avoid errors caused by temperature changes. 9. Automatic axis alignment Easy setup with exact tilt alignment (GL622N only). 10. Mask mode Virtual masking to avoid false measurements caused by glass reflections or interference with other lasers. 11. Model GL622IR Invisible infrared laser beam (Class 1) for special applications where visible beams must be avoided.
