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 PERIODIC as well as APERIODIC instruments.
An arrangement is providedto 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.
