Inclinometers measure the orientation angle of an object with respect to the force of gravity. This is done by means of an accelerometer, which monitors the effect of gravity on a tiny mass suspended in an elastic support structure.

What is the purpose of the inclinometer?

Inclinometers are used to measure displacements in ground and in structures that lie below ground level (e.g. retaining walls).

How accurate are digital inclinometers?

Accuracy. Certain highly sensitive electronic inclinometer sensors can achieve an output resolution to 0.0001°; depending on the technology and angle range, it may be limited to 0.01°.
