Your Style. Our Precision.

Able to monitor four sources at once, the HPVM Pro is the most versatile graphing volt
meter available today, accurate to 2/1000 of a volt.

The HPVM comes equipped with Bluetooth connectivity, allowing it to connect to the
free Aural Sync™ app, optional AuralSync Companion Smartwatch, and other
AuralSync-enabled devices. Use the app to choose any one of ten gauge designs, then
create 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 for
additional mounting options, and a clean look.

Overbuilt To Last

Extremes in vibration, humidity, and temperatures are always attacking everything in
your 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 power
consumption, drawing just 167 milliwatts when it senses a gradual voltage drop without
transients. This ensures minimal battery drain, taking up to 294 days to deplete a fully
charged 100 amp-hour 12V AGM battery.

While in low-power mode, the HPVM Pro continuously monitors cumulative battery
drain. A prominent red warning signal is triggered by significant voltage drops, flagging
potential issues such as excessive parasitic loads or a failing battery. This intelligent
design ensures early detection of power system issues, identifying issues like a weak
battery or excessive parasitic draw, before they become bigger problems.

The system’s rapid response circuitry also ensures immediate reactivation upon
detecting a voltage spike, seamlessly resuming full operation, and offering real-time
updates to keep you informed.
