Digital Panel Voltmeter, 3 1/2" Display, 200A 220V

【Clear LED Display】The 0.56-inch LED digital tube provides an instant and stable reading, allowing for quick visual verification on machine control panels without squinting or angle distortion.
【Simple Flush Mounting】Designed for a 3.5-inch cutout, this meter locks securely onto equipment surfaces with a simple press, eliminating loose wires or external brackets in case of continuous vibration.
【Reliable Terminal Blocks】Wired screw terminals securely hold conductors behind the panel, preventing intermittent signal loss due to accidental pulls or a dusty shop environment.
【Compact Back Profile】The shallow housing fits perfectly into narrow instrumentation cabinets, leaving ample room for internal wiring, relays, and other critical components without clutter.
【Industrial Versatility】Ideal for retrofitting voltmeters, thermostat displays or regulators on factory machines, production lines and generator control panels.
