High Precision Voltmeter (HPVM), Black

Meet the HPVM (High Precision Voltmeter) - the most precise, fastest sampling, smart wireless graphing voltmeter designed for both automotive and car audio enthusiasts. Voltage, whether you're using it to create a spark to create combustion, inverting it to drive an electric motor, or pushing it into your amplifier to move a speaker cone to create sound, is critical in your car. Low voltage creates heat, stresses components, limits output, can affect sound quality, and even leave you stranded (if you don't have enough of it). Make sure your voltage is always on point with the best tool for the job! The HPVM is a high-precision wireless graphing voltmeter with 99.99% accuracy / up to 3 decimal places of precision (e.g., 15.234v), and can monitor up to 2 individual voltage points! See the voltage sag between your alternator, front battery, lithium bank, and/or your amp to ensure your electrical resistance is dialed in and on point! It is physically overbuilt with a solid aluminum case, high-density/temperature internal supports, and gold-plated ENIG PCB to survive the loudest and most violent 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.
