Selecting a Dial Indicator Holder on Amazon.com
A dial indicator holder, such as a clamp, stand, or base, is used to position and secure an indicator for repeated measurements. Indicator accessories may be sold separately, or an indicator may come with a base or other accessories. While many bases are magnetic, an indicator base may alternatively be made of a heavy material such as granite, which provides a stable platform. A dial indicator magnetic base usually has a lever or switch that turns the magnetic force on or off, and a V-shaped groove that allows for attachment to a shaft or other rounded surface. Some indicator stands have a flexible or articulating arm for precise positioning of the indicator. Using an indicator stand or holder enables hands-free measuring during machining, manufacturing, engineering, and research operations.
