This Heavy-Duty Water Temperature Gauge is designed to provide accurate temperature readings from 100°F to 250°F. Ideal for automotive and marine applications, this gauge utilizes a low amperage current that flows through a sending unit with variable resistance. As the temperature changes, so does the resistance, allowing the gauge to accurately display the current water temperature.
