Suunto PM5/SPC Clinometer with Percent and Secant Scales
The Suunto PM-5 hand-held clinometers are used all over the world by foresters, surveyors, engineers, cartographers, geologists, miners and architects and many others to measure heights, vertical angles and slopes quickly, reliably and easily. Since the secant scale clinometer expresses secant of a slope times 100, you should initially divide the clinometer reading by 100 to obtain the correct secant value. For example, a clinometer reading of 110 has a correct secant value of 1.10. ±150% secant values x 100 – 100 to ±500. Percent/degree conversions on back.
