Yokogawa Electric Corporation 250321LSLS Panel Meter

The Yokogawa 250321LSLS is a 3.5-inch analog panel meter from the 250 Series “Big Look” line, designed for clear, real-time electrical indication in control panels, switchboards, and industrial equipment. It provides an analog voltage or current readout (configurable) with a wide-scale dial and an analog needle, typically offering ±2% of full scale accuracy, and uses a pivot & jewel or taut band movement depending on the model. Mounting is panel-mounted with surface or window options, and protective designs range from dust-resistant to IP-rated versions; it complies with ANSI C39.1 and UL/CSA/IEC standards as series dependent. Maintenance technicians, electricians, and system integrators rely on this meter for monitoring and panel instrumentation upgrades, though it is discontinued and available primarily as surplus with limited supply. Common replacements include Yokogawa 251321LSLS and 250320LSLS.
