(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.

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.
The revues I wrote for the pro voltmeter was not clear ! It is a great product and does what is made to do ( and then some!) my reviews was more aimed at the website and myself being upset that I did not end up with the pro bass knob because I proceeded too quickly I would def recommend it to anyone !!
If you don't have one of these for your big audio build, you definitely need one. Stable voltage is critical in big build audio systems. These are real time accurate.
Absolutely hands down best on the market it's a single volt meter capable of reading my Alternator, SCIB LTO bank and both My mono block and 4 channel amp All at the same time LF Audio is changing the game I am legitimately saving to purchase almost every product he makes best quality car audio products on the market
