• VERSATILE 4-IN-1 CUSTOMIZABLE DISPLAY – This Car Instrument consolidates four critical metrics into one sleek LCD screen. Users can freely configure the display modes to show combinations of Voltage, Water Temperature, Oil Pressure, and Fuel Level, eliminating dashboard clutter while providing comprehensive real-time engine health monitoring for any vehicle type.
• INTELLIGENT FUEL GAUGE CALIBRATION – Solves the common pain point of incompatible fuel senders with its advanced self-learning function. The system automatically matches the resistance (5-1000Ω) of any fuel float, while the built-in anti-shake algorithm ensures stable, flicker-free readings even on bumpy off-road trails or when the fuel sloshes in marine applications.
• ULTRA-WIDE VOLTAGE & SAFETY ALARMS – Designed for diverse power systems, this Car Voltmeter operates flawlessly from DC 9V to 36V (tested up to 40V), making it perfect for cars, trucks, and boats. It features smart visual alarms that flash when voltage drops below 10V, exceeds 31V, water temp surpasses 95°C, or oil pressure falls below 0.1MPa, preventing catastrophic engine failure.
• HIGH-PRECISION SENSOR TECHNOLOGY – Utilizing advanced single-chip microcomputer technology, this Water Temp Gauge and Oil Pressure Meter delivers ±0.1% measurement accuracy. The high-brightness LCD offers intuitive, easy-to-read data in all lighting conditions, ensuring you never critical safety parameters during high-speed driving or heavy-load operations.
• ROBUST BUILD & EASY INSTALLATION – Engineered for durability with an ABS and brass construction, this Fuel Gauge withstands extreme temperatures (-40°C to 50°C) and harsh vibrations. Its compact design, low power consumption, and included mounting hardware make it a plug-and-play upgrade for classic car restorations, DIY projects, and heavy-duty machinery replacements.
