Rhé electrometer, designed by Louis Henri Frédéric Melsens, Belgium, c.1875. The device is circular with a wooden casing and a glass top, within which is the magnetised needle resting on top of a card. The card measures 180 degrees in 10-degree increments. Underneath and hidden below the card are the copper wire coil and iron bar. The device is attached to a circuit via conductors positioned at the north and south sides of the casing which connect directly to the internal copper wire coiling.
