2012 Portable DC Ammeter & Voltmeter

Brand: Yokogawa Electric Corporation

Model 2012 is moving coil type instrument using a taut-band suspension system. The suspension system provides excellent reproducibility without friction, and strong resistance to shock impact.

These precision instruments combine a magnetic circuit (sandwich mechanism) that blocks the effects of external magnetic fields, and a superior temperature compensation circuit.
Features
  • Taut-band Suspension System Eliminates Friction and Provides Strong Resistance to Shock Impact
  • Stable Performance Ensures that Changes Over Time are Negligible
  • Quick Response and Easy-to-read Scale
  • Superior Temperature Compensation Circuit Reduces External Temperature Effects
  • Magnetic Circuit (Sandwich Mechanism) Reduces the Effects of External Magnetic Fields
