Self-Damping Clinometer Provides Quick and Easy Measuring

This Self-Damping Clinometer has been used all over the world by surveyors, engineers,cartographers, geologists, miners, architects and others who need to be able to measure heights, vertical angles and slopes quickly and easily. It's less expensive than lasers and the scale has graduations of 1° or 1%, 1' or 1/4m.
Sturdy, aluminum housing resists corrosion and protects against impact. Damping liquid eliminates scale vibration and ensure smooth, accurate and quick readings. Parallax-free (free of displacement and changes) lens magnifies scale card graduations, enabling user to estimate readings to 1/6°. Jewelled bearing assembly ensures long-lasting, accurate operation.
Accuracy: Direct reading to 1° or 1%; estimates to 10 min. or 1/5 of 1%.
Measure 23/4"H x 2"W x 5/8"D. Table of cosines printed on back of instrument.
Complete with neck cord, Skylon case and illustrated instructions. Measures PM-5/SPC/Percent and Secant.
