Such devices were commonly used in laboratories, power plants, research institutes, or testing facilities. It can be an attractive collector's item or an industrial accessory for a retro or technical-style interior. It is also suitable as an educational tool, vividly demonstrating how electrical voltage was measured in the pre-digital era.
