The small optical plummet FG-OLN with Wild/Leica Claw system from FPM is for the exact positioning above reference points.

The FG-OLN is a small optical nadir plummet with an axis system that can rotate freely. Two bubble levels are used to level the instrument.
The adjustable bubble levels provide a sensitivity of 2 arc minutes per 2mm bubble travel.

The advantage of the FG-OLN compared to tribrachs with a built-in optical plummet is that the user can verify whether the plummet is put up correctly or not, simply  by rotating the instrument. If the tripod, tribrach and the plummet are not set up correctly the target point/ reticle will start to move.

The instrument is stored in a padded and water-repellent carrying bag.

Applications:
  • Can be used for the exact positioning of surveying instruments during the erection of high-rise buildings, mine shafts, smokestacks, bridges and steel constructions.
  • Special measurement tasks in industrial surveying and mine surveying
  • Monitor deformation processes at buildings
  • Exact positioning above reference points
