etäisyyspyörät

Etäisyyspyörät, often translated as "distance wheels" or "measuring wheels," are tools used to measure distances over a surface. They typically consist of a wheel attached to a handle, with a mechanical or digital counter that records the number of rotations. As the wheel is rolled along the ground, the counter accumulates the distance covered.

These devices are particularly useful for measuring long or irregular distances where a tape measure might be impractical. Applications include surveying, construction, roadwork, landscaping, and even sports event planning. They are often preferred for their ease of use and ability to cover ground quickly.

There are two main types of etäisyyspyörät: mechanical and digital. Mechanical models use gears and a dial to display the distance, while digital models employ electronic sensors and an LCD screen for a more precise readout. Some advanced models may also include features like memory recall for previous measurements or programmable units of measurement.

When using an etäisyyspyörä, it's important to ensure the wheel makes consistent contact with the surface being measured. Starting and ending points should be clearly marked, and the wheel should be rolled in a straight line as much as possible to achieve accurate results. Calibration may be necessary for highly precise work.
