Moving iron (M.I.) switchboard voltmeter with 90-degree quadrant scale for direct panel mounting. The moving iron movement is robust and accurate, requires no external power supply, and reads true RMS on AC circuits. 48x48mm face. Available in 150V, 300V, and 500VAC full-scale ranges. Commonly used alongside ammeters in switchboard instrument panels for monitoring supply voltage.
Note: Select the voltage range that covers your nominal supply voltage with adequate overscale margin. For current measurement, see the matching Crompton 242 ammeter.
