The GLI20N is a staff level with an adjustable circular bubble for setting levelling staffs plumb. It screws onto the staff or is held by hand against the narrow face. A bubble sensitivity of 25 arcminutes is enough for site and engineering levelling.

Frequently Bought Together

A tilted levelling staff always reads too long. The error grows with the reading height and goes unnoticed in the office because the figure still looks plausible. The GLI20N staff level, made by Nedo for Leica Geosystems, makes that tilt visible before the reading is taken.

Benefits

  • Adjustable circular bubble with 25 arcminutes sensitivity, the staff is brought reliably to vertical instead of being held by eye.
  • Two ways to use it, screwed permanently to the staff for continuous work or held by hand against the narrow face for a quick check.
  • Re-adjustable, the bubble can be set to the staff in the field and stays usable over the service life.
  • Small, rugged part with no electronics and no battery, ready to use and close to maintenance free.
  • Far cheaper than repeating a measurement because of a tilt error on a long levelling line.
