Moving Iron Instruments are generally used for measuring AC Voltages and Currents. A feature of the moving element is that it is fitted with synthetic sapphire jewels. The movement is light and 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 values. They can be used too on AC systems , if the input is fed through bridge rectifiers. A Centre 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 Current and Potential transformers, and external shunts, Accuracy Class: 1 to 1.5% as per ISS 1248/83, we also manufacture.
