A precision-made clinometer for measuring angles of elevation and depression. Scale ‘divided 60° – 0°- 60° with vernier scale reading to 10min. of arc. Includes sighting tube with reflector and spirit level.
Abney Levels are used in Land Surveying which consists of a fixed sighting tube, and a movable bubble level that is connected to a pointing arm, and a protractor scale. The Topographic Abney Level is easy to use, affordable, and when used correctly is a very accurate land surveying and construction tool. Topographic Abney Levels are used to measure degrees, percent of grade, topographic elevation, and chain correction. The user can use trigonometry to determine height, volume, and grade.
