Professional levelling instruments for the building and construction industry.
The Automatic Optical Level works like a precision telescope, with an artificial target line generated at a specified height - the horizontal reference.
An automatic compensator adjusts the target line in the horizontal plane.
Distances can be measured using the stadia lines with the E-graduations on the measuring staff.
The Automatic Optical Level is the 21st Century version of the Cowley Level and the Dumpy Level.
