Sea-Dog Round Voltage & Amp Meter - 6V-30V & 0 Amp - 10 Amp Meter

The Sea-Dog Round Voltage & Amp Meter (Model 421625-1) is a compact digital volt and amp meter designed for marine and electrical system diagnostics across 6V to 30V DC applications with 0–10 amp measurement capability. This instrument combines a ruggedized round form factor—matching standard 12V receptacle dimensions—with IP65 water resistance and a bright red LED display, making it a reliable choice for vessel electrical monitoring, off-grid power systems, and battery-dependent equipment in harsh environments.

Built from injection-molded nylon construction, the meter supports input from 4–30VDC and operates without requiring a separate DC shunt, simplifying installation across diverse electrical configurations. The IP65 rating ensures reliable operation in wet, salt-air, and spray-exposed conditions—critical for offshore vessels, coastal equipment, and environments where corrosion and moisture pose continuous threats. The red LED display remains visible in low-light and high-glare conditions typical of deck work or field electrical troubleshooting.

This meter serves operators managing 12V, 24V, and higher-voltage DC systems who need instant voltage and current feedback without external sensing hardware. Marine technicians, boat owners managing battery banks, emergency power systems, and off-road equipment operators rely on this class of instrument to diagnose electrical faults, verify charging performance, and monitor load draw. The compact round design allows flush panel mounting or integration into existing instrument clusters without requiring extensive re-fabrication.

Sea-Dog has established a reputation for marine-grade electrical components that withstand saltwater exposure and vibration-intensive environments. The 421625-1 follows that standard, offering the durability and precision necessary for continuous electrical system monitoring in demanding operational settings.
