2-1/16 Gauge Water Temp 100-300F

The AutoMeter 2-1/16" Water Temperature Gauge (Model 9255) is a full-sweep electric analog gauge engineered for extreme environment performance. With a temperature range of 100–300°F and stepper motor precision, this gauge delivers reliable water temp monitoring across high-heat applications including heavy-duty engines, marine powerplants, and performance automotive builds where accuracy under stress is non-negotiable.

The 2-1/16-inch diameter housing fits standard automotive instrument clusters and dashboard applications, while the black face provides high contrast readability in varying lighting conditions. Full-sweep stepper motor operation ensures smooth, responsive needle movement across the entire 100–300°F span—critical for detecting gradual thermal rise before system stress becomes dangerous. The electric design eliminates mechanical linkage, improving durability and reducing installation complexity compared to mechanical sender-based systems.

This gauge is built for users who demand precision monitoring in demanding thermal environments: racing teams managing engine bay temperatures during sustained competition, heavy truck operators monitoring coolant temps under full load, and marine enthusiasts running high-output engines where water temperature stability directly impacts performance and longevity. The extreme environment rating reflects AutoMeter's engineering focus on reliability where commercial-grade accuracy matters.

AutoMeter water temperature gauges are industry standard in performance and commercial vehicle applications. The 9255 combines stepper motor smoothness with the thermal range needed for modern high-output powerplants, making it a direct replacement for OEM and aftermarket gauge systems that require precise 100–300°F monitoring capability.
