Product information ‘FET 220K-L’

For measuring horizontal, vertical and zenith angles. For use in building construction / civil engineering for vertical positioning of formwork, precast elements or columns.

Extremely user-friendly: large display on both sides with easy-to-read values, a laser plummet for convenient positioning above the ground point and much more.

FET 220K-L - Highlights:

This is what you call user-friendly: Simple and precise levelling in both X and Y axes without the need for tedious turning of the instrument using the electronic base level in the display.
Helpful: Coaxial laser beam integrated in the telescope and can be focussed on the target.
Measurement reliability: 2-axis compensator of the target and transverse axis for automatic correction of small residual inclinations of the displayed vertical angles.   

Features

- Large, easy-to-read display on both sides
- Laser plumb for easy alignment above ground point
- Illumination of telescope field of view and display
- Horizontal circle: Hold function, 0 position at any position, clockwise or anticlockwise reading
- Vertical circle: reading in gon / degrees / per cent
