Blue Sea 8018 DC Analog Ammeter - 2-3/4" Face, 0-150 Amperes DC

The Blue Sea 8018 DC Analog Ammeter is an essential instrument for any vehicle electrical system where monitoring current draw is critical to performance and reliability. Whether you're running auxiliary lighting, high-output alternator systems, or complex off-road power distributions, this 2-3/4-inch face ammeter provides real-time visibility into your electrical load in the 0–150 ampere DC range.

Built by Blue Sea Systems, known for their high-quality marine and automotive DC electrical components, the 8018 utilizes analog needle display technology that requires no batteries or external power to function. The robust 150-ampere full-scale reading covers virtually all 12V and 24V direct-current applications, making it suitable for stock vehicles and heavily modified dual-alternator setups alike.

This ammeter is ideal for truck builders, RV and camper system integrators, and serious off-roaders who need to verify alternator health and load distribution. Its industrial-grade movement is designed to handle vibration, thermal cycling, and constant use without calibration drift, providing a reliability advantage over cheaper digital alternatives.
