Clinometer: What It Is & How to Use It
A clinometer (also called an inclinometer) is a precision instrument used to measure angles of slope, elevation, or inclination of an object with respect to gravity.
What Is a Clinometer?
A clinometer measures the angle between a surface and the horizontal plane. It's essential in surveying, forestry, geology, construction, and navigation.
Types of Clinometers
- Mechanical clinometers: Use a weighted pendulum or bubble level to indicate angles.
- Digital clinometers: Use electronic sensors (accelerometers) for precise readings.
- Optical clinometers: Combine optics with angular measurement for surveying.
- Smartphone apps: Use the phone's built-in accelerometer as a basic clinometer.
How to Use a Clinometer
- Hold the clinometer at eye level or place it on the surface to measure.
- Sight along the clinometer toward your target point.
- Read the angle displayed on the scale or digital readout.
- Record the measurement for your calculations.
Common Applications
- Forestry: Measuring tree heights
- Construction: Checking roof pitch and drainage slopes
- Geology: Measuring rock strata inclination
- Navigation: Determining latitude using celestial objects
- Sports: Measuring ski slope steepness
