Sierra Digital Voltmeter — 1-1/8" Panel Mount
A straightforward, reliable digital voltmeter for monitoring DC system voltage from any standard 1-1/8" panel cutout. The Sierra EA01070 delivers a precise 3-digit LED readout across a 2.5–30V DC range — compatible with both 12V and 24V systems. Self-powered from the circuit being measured, it requires only a 2-wire connection with no separate power feed needed. Housed in a sealed uni-body polycarbonate case and IP67 rated, it handles the moisture, dust, and vibration of everyday marine use without issue.

Parts Desk Insights
Best Use Case: This is the right entry-level voltmeter for customers who need a clean, accurate digital voltage display in a standard 1-1/8" cutout without the added cost of a graph display. It’s a solid choice for monitoring a single battery bank or DC system on smaller boats, tenders, or any application where simplicity and value are the priority. For customers who want the circumferential battery level graph alongside the digital readout, step them up to the EA01090 (11-EA01090) at the same 1-1/8" cutout. For Contura switch panel installations, recommend the EA01080 (11-EA01080) instead.
