• Multi-Function Monitoring - This 4-in-1 instrument displays voltage, fuel level, water temperature, and oil pressure in any combination. It works with DC 9V-36V systems, ensuring accurate readings even at 40V for cars, trucks, and RVs.
• Vibration-Proof Fuel Sensor - Digital fuel meter withstands shaking from bumpy roads or open oil floats, maintaining stable and precise readings. Auto-learning function automatically matches any oil float impedance for universal vehicle compatibility.
• Quick Setup & Alerts - Fuel sensor supports fast model selection with pre-set options. Built-in alarms flash for critical issues: low voltage (<10V), high temperature (>95°C), low oil pressure (<0.1mp), and fuel level below 10%.
• Wide Environment Compatibility - Operates in extreme conditions from -40°C to 50°C and 45%-75% humidity. Brass and ABS construction ensures durability and consistent performance in all driving scenarios.
• Accurate Measurement - Achieves ±0.1% accuracy for voltage, water temperature, and oil pressure, with ±1% for fuel impedance. Prevents motor damage by providing real-time data and alerts for proactive vehicle maintenance.
