GFUVE Launches GF312V2 Portable Three-Phase Watt-Hour Meter Calibrator – Redefining Precision in On-Site Electrical TestingJune 22, 2026

[Beijing, China] – [2026.6.22] — GFUVE Group, a leading innovator in electrical test equipment, is proud to announce the global release of its latest flagship product: the GF312V2 Portable Three-Phase Multifunction Watt-Hour Meter Calibrator. Designed with extensive user research and integrated with cutting-edge technologies from home and abroad, this device sets a new benchmark for accuracy, portability, and functionality in on-site energy meter calibration and electrical parameter measurement.
Unmatched Precision and Advanced Technology
The GF312V2 stands out with its high-performance technical core. Equipped with a high-speed A/D converter and DSP digital processing system, the calibrator delivers exceptional measurement accuracy and stability, available in accuracy classes 0.02%, 0.05%, and 0.1%. Its 32-bit ARM embedded processor ensures a user-friendly experience with a sleek interface, intuitive operation, and reliable performance—making complex electrical tests accessible to professionals across industries.
With a voltage measurement range of 0-600V and current range of 1mA-12A (or 1mA-120A for direct connection), the device supports clamp-on CTs (optional ranges: 5A to 3000A) for flexible on-site applications. It accurately measures key electrical parameters including voltage (U), current (I), active/reactive/apparent power (P/Q/S), phase angle, power factor, frequency, and harmonics (2nd to 63rd order), meeting the diverse needs of precision testing.
Versatile Applications for Global Industries
