Car Audio LF-HPVM-PRO Smart Wireless Graphing Voltmeter with 4-Point Monitoring
This listing includes:
- (1) LF Audio High Precision Voltmeter PRO (4-Point Monitoring)
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.
