Clinometer
From Free net encyclopedia
A clinometer AKA inclinometer is an instrument for measuring vertical angles. Modern ones output electronically and are accurate to .001 degrees. The earliest clinometers used a weight, an extension, and a potentiometer. In the 1980s electronic sensors using alcohol over capacitive sensors were popular. Modern clinometers use MEMs due to their tiny size and low cost.

Examples Of Usage
Clinometers are used for:
Measuring the slope angle of a tape or chain during distance measurement. Estimating the height of a building or other feature using a vertical angle and a distance (determined by taping or pacing).

Factors Which Influence The Use Of Clinometers
- A clear line of sight between the user and the measured point is needed.
- A well defined object is required to obtain the maximum precison.
- The angle measurement precision and accuracy is limited to slightly better than one degree of arc.
