Century meters have plastic cases with glass windows and are UL Recognized. All Century DC meters have self-shielding movement (calibration is not affected by stray magnetic field or magnetic mounting). The listed AC meters have iron-vane type movements and are calibrated at 60 Hz. Other meter sizes and ranges are available, call Allied for details.
