(HPVM-PRO) High Precision Voltmeter - Pro
Meet the HPVM PRO (High Precision Voltmeter), our bigger version of the most precise, fastest-sampling smart wireless voltmeter designed for automotive and car audio enthusiasts.
Understanding the crucial role of voltage in your car is key. Whether it's sparking combustion, driving an electric motor, or powering your amplifier to create sound, voltage is at the heart of it all. Low voltage can lead to heat, component stress, limited output, sound quality issues, and even leave you stranded. Ensure your voltage is always optimal with the HPVM PRO, the ultimate tool for the job!
The HPVM is a high-precision wireless graphing voltmeter with 99.99% accuracy and up to 3 decimal places of precision (e.g., 15.234v). It can monitor up to 4 individual voltage points! See the voltage sag between your alternator, front battery, lithium bank, and amp to ensure your electrical resistance is dialed in and on point!
The HPVM PRO is not just a high-performance tool, it's also built to last. With a robust solid aluminum case, high-density/temperature internal supports, and a gold-plated ENIG PCB, it's designed to withstand extreme conditions and the loudest, most aggressive builds.
Onboard AuralSync™ technology lets you connect the voltmeter to your smartphone, our AuralSync Companion Smartwatch, and other LF Audio AuralSync™ enabled devices.
For instructions on connecting your HPVM, updating firmware, using the app, and more, please see our getting started page.

Customer Reviews
Best device for any car audio enthusiasts it not comparable to any other volt meter when it comes to quality , accuracy, and speed I’ve already fixed one issue just getting this and I now know I need to up my charging
Excellent and accurate product!
I honestly didn't think the HPVM could be outdone but here we are.
Same ridiculously fast refresh rate and accuracy but with more options and a much larger screen. Still compact enough to fit anywhere in a dash or center console, too.
LF Audio is top notch, hands down.
If you don’t think you need this volt meter, you need this meter. The capability to monitor (4) different sources of your audio system is huge . I can see how my truck handles the bass with my current set up identifying any power drops that are more than what I want… I tested all points against my fluke and no + or - was needed for adjustment in HPVM.
