Silverline 633665 Automatic Optical Level

Silverline 633665 Automatic Optical Level

• The automatic optical level works like a precision telescope and allows an artificial target line, the horizontal reference to be created at a certain height.
• The height difference between various measuring points and the horizontal reference line can be read off using a levelling staff.
• The self-levelling fuction automatically aligns the target line by itself, guaranteeing maximum measuring accuracy in all conditions.
• Magnification X20. Image: erect, accurate to +/- 2.5mm over 1km distance.
• Field of view 1degree 20. Objective aperture 34mm. Minimum focus 0.5m, 360degree circle.
• Compensator range +/-15 degree, compensator accuracy +/- 0.8.
