⁠Spot Reflecting Galvanometer

Specification: 

A spot reflecting galvanometer is a highly sensitive electromechanical instrument used to detect and measure extremely small electric currents or voltages. It functions by reflecting a beam of light from a mirror attached to a moving coil onto a graduated scale, allowing for precise visual indication of current flow in physics and electrical engineering laboratories.

Technical Specifications:
* Sensitivity: Typically ranging from 10⁻⁸ to 10⁻⁹ Amperes per millimeter division
* Coil Resistance: Commonly available in 50, 100, or 500 ohms
* Period of Oscillation: Approximately 2 to 4 seconds
* Mirror Type: Concave, front-surface silvered mirror
* Damping: Air or electromagnetic damping
* Scale illumination: Integrated low-voltage LED or incandescent lamp
* Mounting: Adjustable leveling feet with integrated spirit level
