etäisyyspyörä

The etäisyyspyörä, which translates to "distance wheel" or "measuring wheel" in English, is a device used for measuring distances over the ground. It typically consists of a wheel attached to a handle with a measuring mechanism. As the wheel is rolled along the desired path, the mechanism counts the rotations and converts them into a distance reading, often displayed on a counter or digital screen.

These devices are particularly useful for measuring long or irregular distances where a tape measure would be impractical. They are commonly used by surveyors, construction workers, road maintenance crews, and even gardeners. Some etäisyyspyörät are designed for indoor use, while others are more robust and suited for outdoor environments, capable of handling uneven terrain.

The accuracy of an etäisyyspyörä can vary depending on its design and the surface it is used on. Factors such as tire inflation, wheel slippage, and the calibration of the device can affect the precision of the measurement. Many modern versions offer features like memory functions, unit conversions, and even GPS integration for enhanced functionality. The simplicity and portability of the etäisyyspyörä make it a practical tool for a wide range of distance measurement tasks.
