2-1/16 U/L Water Temp Gauge 100-250 Deg

The 2-1/16 U/L Water Temp Gauge 100-250 Deg by AutoMeter is a professional-grade analog instrument designed for marine and automotive applications requiring reliable engine temperature monitoring. Built for operators and technicians who demand accuracy in critical cooling-system diagnostics, this electric water temperature gauge provides real-time thermal feedback essential for engine longevity and performance. Whether deployed in tactical vehicles, marine platforms, or high-performance equipment, this gauge delivers the dependable readout necessary for preventive maintenance and operational awareness.

This electric gauge employs AutoMeter's proven short-sweep analog movement, translating engine coolant temperature directly into precise needle deflection across a 100–250°F range—the operating window critical for early detection of overheating or cooling-system failure. The 2-1/16-inch diameter face and silver finish provide high contrast and legibility in varied lighting conditions, from low-light cockpits to full daylight environments. Electric operation eliminates mechanical lag, offering near-instantaneous response to temperature changes, while the compact dimensions (4.7 x 4.5 x 5.1 inches) and lightweight profile (0.46 lbs) facilitate flexible panel mounting without weight penalty.

Technicians and operators in marine, automotive, and specialty vehicle sectors benefit most from this gauge's reliability and accuracy during both routine diagnostics and dynamic field conditions. Installation requires connection to a coolant-sensing sender unit and 12-volt electrical supply; compatibility with existing marine and automotive wiring harnesses is standard. The Pro-Comp Marine series designation underscores suitability for saltwater and freshwater environments, making it ideal for naval auxiliary equipment, boat engines, and waterborne tactical platforms where corrosion resistance and precision instrumentation are non-negotiable.
