The unit features a built-in step-down transformer that plugs directly into standard AC mains power.
3. Can the lamp focus and zero spot be easily adjusted?
Yes, external knobs are provided for sharp focusing of the light spot and quick zero-line alignment.
4. What experiments typically require this galvanometer?
It is widely used in Wheatstone bridge circuits, potentiometer calibrations, thermoelectricity tests, and low-current research.
5. Is this instrument suitable for international university exports?
Yes, our optical galvanometers meet global educational standards and are exported worldwide alongside Heat Apparatus and Magnets.
6. Do you offer bulk institutional pricing?
