Plastic Ballistic Galvanometer, Color : Black for Laboratory Use

These galvanometer are rigid in construction, beautiful in design and easy to operate, with large periodic time. The moving coil carries a specially polished front silvering concave mirror of 100cm. focal length, suitable for use with COMETEK Lamp and Scale Arrangement.

Large moment of Inertia of the moving part of the galvanometer.

COMETEK 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.
