Moving Coil Ammeters & Voltmeters


DESCRIPTION

Brand Moving Coil Ammeters& Voltmeters are recommended to be used for measuring DC voltage and current. Moving Coil Instruments are protected from damage or breakage under adverse conditions due to spring loaded jewel & pivot system. These Instruments are fitted with high flux density magnets resulting in linear scale.
These instruments are housed in dust tight and high heat resistant case of ABS plastic/ Bakelite/Sheet Metal/Wooden.

Ammeters with internal shunts are available up to 30 Amps and for higher currents up to 12000 Amps use external shunts of 50mV, 60mV, 75mV etc.
