What is a Parallelometer?

A parallelometer is a device used to measure the angle between two lines or surfaces that are not parallel to each other. It is commonly used in metrology and inspection applications to determine the accuracy of parts and assemblies.

The parallelometer works by positioning one line or surface on a reference plate, and the other line or surface on a movable arm. The angle between the two lines or surfaces is then measured using a precision measuring instrument, such as a dial indicator or a laser interferometer. The angle can be read directly from the instrument or recorded electronically for further analysis.

There are different types of parallelometers available, including manual, semi-automatic, and fully automatic models. Some parallelometers may also include additional features, such as the ability to measure angles in multiple planes or to perform other metrology tasks, such as surface roughness measurement.

In summary, a parallelometer is a precision measuring instrument used to determine the angle between two lines or surfaces that are not parallel to each other. It is commonly used in metrology and inspection applications to ensure the accuracy of parts and assemblies.
