What Is an MR66 Moving Coil Meter?

The MR66 Moving Coil Meter is an analog electrical measuring instrument based on the Permanent Magnet Moving Coil (PMMC) principle. It is designed to measure direct current (DC), voltage, or very small electrical currents depending on the selected model.

Its precision movement ensures accurate and stable readings, making it suitable for laboratory experiments and electrical testing.

Working Principle

The MR66 Meter operates on the Permanent Magnet Moving Coil (PMMC) principle.

When electric current flows through the moving coil:

• A magnetic field is produced around the coil.
• The interaction between the coil and the permanent magnet generates torque.
• The pointer moves proportionally across the calibrated scale.
• The deflection indicates the measured electrical quantity.

This mechanism provides high sensitivity and excellent measurement accuracy.
