Description

For sale here is from Germany FREIBERGER GEOLOGIST'S COMPASS OR1249.
The Orginal German Made Structual Geological Compass -General field-geological work
-Special structural-geological, deposit-tectonic, and engineering-geological rockmechanical work
-Can be used for route surveying, for the survey of natural and artificial openings above and below ground
-For staking out and dimensioning holes -For the transfer of geological data into maps and plans -Rockwork as well as moderate-accuracy surveying -Ground magnetic needle placed on edge.
-Permanent locking of the magnetic system - can be released during measurement by depressing the push-button and should be used for shortening the setting time
-Easy adjustment of the graduated circle
- for each measuring technique and for setting declination values of any magnitude
-Lockable inclinometer for inclination measurements of high accuracy
-Colour coding on circle of altitude and magnetic needle (according to Clar)
- unambiguous determination of the direction of dip of geological formations
-Circular spirit level for levelling, lateral glass tube for measurement at points of difficult access
-Dip measuring plate -Reading of dip angle -Protection for the glass cover Technical data Compass circle Diameter 45 mm scale value 2 (2 gon) estimation 0,5 (0,5 gon) Azimuth circle diameter 22 mm scale value 5 (5 gon) estimation 1 (1 gon) Clinometer measuring range +90 (+100gon) scale value 2 (2 gon) estimation 0,5 (0,5 gon) Contact edge graduated length 70 mm scale value 1 mm Function data initial oscillation time <50 sec of the magnetic needle accuracy of direction +0,5 (+0,5gon) reading declination optional setting tilting range of the 225 (250 gon) dip measuring plate circular level ca.
