How to Make a Clinometer

Clinometers are used to measure the height of tall objects such as building and trees. Astronomers use clinometers to calculate the degrees above the horizon where objects can be seen in the night sky. A clinometer can cost quite a bit, but a homemade clinometer can be just as effective and easy to make.

Instructions

    • 1

      Buy a plastic protractor or make one from heavy posterboard or cardboard.

    • 2

      Tape a standard drinking straw to the straight edge of the protractor. This will be your scope.

    • 3

      Attach string to the straw at the 0 degree mark.

    • 4

      Tie a light weight to the string. You can use a washer or a screw or anything else that can balance the clinometer and be unobtrusive.

    • 5

      Sight a tall object to make sure the clinometer was constructed correctly.
