Cathetometer

A cathetometer is a type of optical instrument used for measuring vertical distances or heights. It consists of a vertical column with a scale, a telescope mounted on a carriage that can move up and down the column, and a vernier scale for precise measurements.

Cathetometers are commonly used in surveying, engineering, and physics laboratories for measuring the height of objects, determining the difference in elevation between two points, or for leveling purposes. They are particularly useful when high accuracy is required.

In the supply class Optical Instruments, Test Equipment, Components And Accessories, cathetometers are categorized as instruments used for optical measurements. They are often found in the supply group Instruments And Laboratory Equipment, which includes a wide range of instruments and equipment used in scientific research, experimentation, and analysis in laboratory settings.
