3030 COCLA Stratum Compass
PRECISION CLAR METHOD STRATUM COMPASSWorld-renowned geological stratum compass designed for measuring the azimuth of dip and the angle of dip in a single operation according to the Clar method, featuring eddy current damping and external declination adjustment.
Measurement MethodSimultaneous two-axis Clar method (measures azimuth of dip and dip angle in one single operation)
Compass Circle50 mm graduated circle with 1° / 1g graduation and anti-clockwise numbering for direct azimuth reading
Configuration, availability and delivery confirmed with your quotation.
01 / FIELD CAPABILITIES
Built for the task.
- Unique Clar design allows instantaneous one-step reading of structural rock strike, dip direction, and dip angle
- Eddy current damping brings the magnetic needle to a rapid rest without mechanical needle bounce
- Automatic needle arresting mechanism locks the jewel bearing securely when the protective lid is closed
- Integrated external declination gear allows quick correction for local magnetic variation without opening the seal
- Precision-machined non-magnetic German alloy casing ensures lifetime reliability in demanding mining environments
