Blue Sea 8251 DC Digital Voltmeter w/Alarm [8251]

The Blue Sea Systems 8251 displays DC voltage from 0 to 60 volts, helping operators monitor electrical-system status from a panel or helm. High- and low-voltage audio and visual alarms draw attention to readings that require inspection. Three display-brightness levels improve readability, while programmable sleep mode blanks the display to conserve power. The splashproof front suits the practical demands of onboard and vehicle installations.
