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.
Suunto height meter PM-5/1520 is an instrument for measuring heights, especially heights of trees, with great accuracy and speed. It can also be used to determine the angle of a gradient. The body of the instrument is corrosion-resistant anodized aluminium-alloy. The scale card runs on a special bearing in a hermetically sealed plastic container filled with a liquid which guarantees that it runs freely and stops quickly. The liquid will not freeze, retains full damping properties in working conditions and eliminates irritating scale vibrations.
When measured from distances of 15 m and 20 m, tree heights can be read straight off the instrument’s scales. The readings should be doubled when measuring from distances of 30 m and 40 m. The Suunto height metre can also be used to determine the angle of a gradient, the reading obtained can be checked in the conversion table on the back of the instrument.
