Description
The Speedhut 3-3/8″ Met OilTemp/Volts/Oil PSI/Fuel Quad Gauge (R3-QG3-LEG) offers a streamlined solution for monitoring your vehicle’s most critical systems. This all-in-one gauge displays Celsius oil temperature, battery voltage, oil pressure, and fuel level, providing essential information in a clear and concise format. Its classic design ensures it integrates seamlessly into a variety of dashboards, offering both functionality and a clean aesthetic. By combining four vital readings into a single unit, this gauge helps you stay informed about your vehicle’s health, allowing for proactive maintenance and a greater sense of driving confidence.
KEY FEATURES AND BENEFITS:
- This Speedhut Quad Gauge consolidates four crucial measurements into one easy-to-read instrument. It displays oil temperature in Celsius (ranging from 40 to 150°C), monitors your vehicle’s electrical system with a 6-18 volt range, tracks oil pressure from 0 to 100 psi, and indicates the fuel level from empty to full (compatible with fuel level sensors with a resistance of 300 ohms or less). The 3-3/8 inch size ensures it’s prominent yet space-saving on your dashboard.
- A built-in warning light can alert you to potential issues.
- The gauge is designed for metric readings, catering to users who prefer the Celsius and PSI units.
- It ships complete with the necessary sensors (temperature and pressure) and wiring harnesses, simplifying the installation process.
