Description Notes

Chaix ‘universal’ compass clinometer, by Lecomte & Deglise, c. 1960.

Compass and clinometer set in hinged metal alloy case. Compass with liquid suspended compass plate marked with an 8 point compass rose. The inner scale runs 0 - 360˚ and the outer scale runs 0 - 360˚ starting from the 180˚ point of the inner scale. The numbers of the outer scale are printed back to front for use with the glass prism lens when the instrument is held in a vertical position. Both scales are marked for each degree and numbered every 10˚. There is a lens bubble in the glass to magnify the scale. There is also a rotatable outside scale marked with the cardinal points. A hinged metal frame lifts the glass prism lens out of a recess and into position over the scale. There is also a round bubble level.

On the opposite leaf is a clinometer with graduated scale. The scale is dissected 0˚ - 90˚- 0˚ - 90˚ - 0˚. The face also has three other scales marked ‘Grades’, ‘Dendrometre’ and ‘Degrés’. There is a fold-up metal alloy sight with cross-hair. The sight is marked wth two scales.

The instrument comes with a tan leather carry case and instruction booklet. Instruction booklet is located in object history file.
