Moving Coil Rectifier AC Instruments are suitable for the measurement of AC currents and voltages. These are permanent magnet (Alnico high flux density) type with pivot-jewel suspension with rectifier circuit. The movement is having high torque to weight ratio and linear one with knife edge pointer for accurate reading.
The design and construction of instruments is most modern. Sturdiness, simplicity, sensitivity and rigid quality control ensure these movements for high grade performance under adverse conditions of shock and vibration. All instruments are housed in ABS moulded dust proof cases with zero adjuster accessible from the front.
