PM-5

OPTICAL READING CLINOMETER

The sturdy pocket-size construction renders the SUUNTO CLINOMETER most suitable for every type of work. Easy for rapid reading through a parallax-free lens is incorporated into the design.

Sighting and scale reading are done simultaneously. There are no screws to turn, no bubbles to center, and nothing to adjust.

Where space is limited, as in geological and mineralogical work, the inclination of strata and other formations can be read placing the instrument along the contour or surface of the formation and reading the angle directly through the side window.

Construction features

The framework is of corrosion resistant light-weight aluminum.

The scale card is supported by a jewel bearing assembly and all moving parts are immersed in a damping liquid inside a high strength hermetically sealed plastic container. The liquid dampens all undue scale vibrations and permits a smooth shockless movement of the scale card.
