- These galvanometer are rigid in construction, beautiful in design and easy to operate, with large periodic time.
- Large moment of Inertia of the moving part of the galvanometer.
- Deflection closely proportional to the electric charge.
- BESTO Ballistic Galvanometers undergo strict laboratory check before dispatch and are suitable for direct deflection measurements which are closely proportional to the current.
- These galvanometers can be used both as PERIODIC as well as APERIODIC instruments.
- An arrangement is provided in the instrument to make it APERIODIC by introducing a suitable resistance in parallel with the moving coil system.
- Zero adjusting and locking devices are provided. The Phosphor-bronze suspension strip prevents shifting of zero.
- The moving coil carries a specially polished front silvering concave mirror of 100cm. focal length, suitable for use with BESTO Lamp and Scale Arrangement
