Moving
Iron Instruments
are generally used for measuring AC Voltage and
Currents. A feature of the moving element is that
it is fitted with synthetic sapphire jewels. The
movement is light, quick acting, but extremely
robust. An efficient system of fluid damping is
employed. The movement is efficiently shielded
against the effect of external magnetic fields.

Moving
Coil Instruments
are used for measuring DC quantities. They can
be used on AC systems when fed through bridge
rectifiers. Center magnet system is incorporated
in our moving coil instruments which completely
shields the movement from the effect of external
magnetic fields. The movement is pivoted between
synthetic sapphire jewel bearings for frictionless
operation.

The
above meters can be used for higher ranges by
using necessary CT/PT and external shunts. These
are also manufactured and offered by us.
