(HPVM-PRO) High Precision Voltmeter - Pro
Description
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 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.

Great little meter. Love the 4 channel so up. Now I can monitor everything in one spot
Absolutely amazing voltage meter A+
Awesome equipment, very well made. Price is awesome too. I'll be buying many more for installs.dont hesitate, well worth it.
This thing is amazing. Very accurate and extremely easy to use. The app is great, using it to change the face and customization of the voltage range is great. It’s also easy on the eyes. Costumer service is also great.
I've always been a fan of the SMD voltmeters with how quick they respond. Only issue was they are hard to read at a quick glance.
Not only does the HPVM-PRO have a quick refresh rate it's easy to ready. I love how I can see voltage from my amps, both battery banks and alternator on 1 screen. I can see how my electrical is behaving and make it easier to spot any problems.
