Silicone dampened air core movements for steady readings and vibration resistance. Knurled mounting nuts for easy installation. Glass filled nylon case resists corrosion and vibration. Water resistant and lenses are glass, not plastic, so they are scratch resistant. Plated mounting hardware prevents corrosion.
Mechanical gauges use precision hobbed brass gears for long life.
12 VDC operation, negative ground. Mounting hardware and light kit with 12 VDC light included. Bright, attractive packaging improves product visibility on display. This constant monitoring of temperature changes alerts the driver to temperature problems well before indications would be received from a typical water temperature gauge. Equipment operators use pyrometers to diagnose engine problems and drive more efficiently, prolonging engine life and reducing fuel consumption.
