Yokogawa Electric Corporation 250-4 Panel Meter

The Yokogawa Electric Corporation 250-4 panel meter is an analog, panel-mounted electrical parameter meter (MPN: 250-4) in the Yokogawa 250 series with the New Big Look design, built for industrial control panels. Readouts appear on an analog dial with a needle pointer and the unit supports AC or DC measurements depending on configuration, with typical accuracy of ±2% of full scale and a frequency range of roughly 25–400 Hz for AC variants. Commonly installed in electrical distribution boards, switchgear, generator systems, motor control centers, and automation panels, it provides real-time visibility into electrical values for operators and maintenance personnel. The meter is housed in an industrial-grade enclosure with a protective front cover to withstand harsh industrial environments.
