High Precision Voltmeter - Pro

HPVM Pro Voltage Meter Precision volt meter for automotive and car audio 2-inch LCD with 65,000 colors Monitors four sources simultaneously Measures up to 18 volts Customizable display with ten gauge faces Bluetooth-enabled connection with free AuralSync app Your Style. Our Precision. Able to monitor four sources at once, the HPVM Pro is the most versatile graphing voltmeter available today, accurate to 2/1000 of a volt. The HPVM comes equipped with Bluetooth connectivity, allowing it to connect to thefree Aural Sync™ app, optional AuralSync Companion Smartwatch, and otherAuralSync-enabled devices. Use the app to choose any one of ten gauge designs, thencreate user-definable voltage ranges and custom colors to make each look match your needs, and your style The HPVM also features wiring terminals on the back and bottom of the unit foradditional mounting options, and a clean look. Overbuilt To Last Extremes in vibration, humidity, and temperatures are always attacking everything inyour vehicle. A solid aluminum case houses high-density/temperature internal supports,and gold-plated ENIG PCB to survive – and thrive – in any build. Advanced Power Management The HPVM’s innovative Deep Sleep mode is engineered to minimize powerconsumption, drawing just 167 milliwatts when it senses a gradual voltage drop withouttransients. This ensures minimal battery drain, taking up to 294 days to deplete a fullycharged 100 amp-hour 12V AGM battery. While in low-power mode, the HPVM Pro continuously monitors cumulative batterydrain. A prominent red warning signal is triggered by significant voltage drops, flaggingpotential issues such as excessive parasitic loads or a failing battery. This intelligentdesign ensures early detection of power system issues, identifying issues like a weakbattery or excessive parasitic draw, before they become bigger problems. The system’s rapid response circuitry also ensures immediate reactivation upondetecting a voltage spike, seamlessly resuming full operation, and offering real-timeupdates to keep you informed.
