YOKINS
MOVING COIL PANEL METERS (TYPE MR-144 , MR-96, MR-72)
YOKINS Switchboard Instruments are permanent magnet (Alnico
high flux density) moving coil type with pivot-jewel suspension.
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 form the front.
