(HPVM) High Precision Voltmeter
Description
HPVM Voltage Meter
- Precision volt meter for automotive and car audio
- 1.3-inch LCD with 65,000 colors
- Monitors two sources at once
- Measures up to 18 volts
- Customizable display with ten gauge faces
- Bluetooth-enabled connection with free AuralSync app
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.

Quality built, fast readings,accurate, easy to install, and program. Badass options to customize the display.
I replaced my Usain Volt meter with it.Fast response time to display voltage. Awesome options. Durabile af. Looks badass wherever it's mounted.
Works exactly as advertised. Multiple gauge faces with 4 position viewing and decimal adjustability is great. I'm running 1 decimal place on a single signal. Works great. Matches my dmm exactly. Good work. Con would be it's a little small, but it's really not because the screen is clear and bright enough.
It took a couple days for it to be shipped out. And over a week for it to come in. Which ok not that big of a deal. I would just very surprised how it came in a tiny box and that was it. No instructions or owners manual nothing just the volt meter. Didn't really understand that. And it was much smaller than I thought it would be. Idk for $200 I just expected it to come with a owners manual at bare minimum. And that it was gonna be bigger than it actually is. But everyone raves about these. So I don't want to be too hard on it. I will say it does feel very solidly built. Can't wait to hook it up.
Hi Dane, because the Voltmeter utilizes Firmware that can be updated over-the-air, including a traditional physical install guide that can be outdated is not optimal. The box has a QR code which takes you to the getting started site where instructional videos are available.
I give the quality volt meter a 5 star rating with out testing it. Only by handling out of package. Great job guys. Very nice product and another 5 star after powering it on. JEREMY S
