HPVM Voltage Meter
- Precision volt meter for automotive and car audio

Your Style. Our Precision.
The HPVM is the most versatile graphing volt meter available today. Accurate to 1/500 of a volt and capable of measuring two sources simultaneously, 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.
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.
Maximum Battery Efficiency
To save your battery power, the HPVM is equipped with Deep Sleep mode. When a gradual voltage drop with no transients is detected, the meter automatically reduces power consumption to just 167 milliwatts. At that rate, it would take 7,059 hours (294 days) to fully drain a 100 amp hour 12V AGM battery.
Once the meter detects a voltage spike, it instantly returns to full operation. It will also display total battery drain during low-power mode and issue a bright red warning if the voltage drop was significant, signaling a weak battery or excessive parasitic draw.
