Import 3-Ph Power Meter Calibrator With Printer — Buy in wholesale FOB from Supplier in China

The GF312B is a portable three-phase energy meter calibrator with an integrated thermal printer, manufactured by Beijing Gfuve Electronics Co., Ltd. in China. It calibrates three-phase, single-phase, active and reactive energy meter errors with accuracy classes of 0.05%, 0.1% and 0.2%. The voltage test range spans 0-600V, and the unit weighs 12kg with an IP65 enclosure rating for field use. A built-in micro printer generates hard-copy calibration certificates on site, removing dependency on separate recording equipment.

The instrument measures harmonic content from the 2nd to 64th order, critical for assessing modern non-linear loads and grid-connected inverters. The 0.05% accuracy class positions it for utility-grade and laboratory reference work, while the 0.2% class suits routine industrial commissioning. Standard field calibration protocols for this class of equipment typically require traceability to national voltage, current and phase-angle standards. The IP65 rating ensures dust tightness and protection against water jets, enabling outdoor substation and switchyard deployment without additional weather shielding.

Primary buyers include state grid corporations, independent power producers, meter manufacturers and third-party calibration laboratories across Asia, Africa and Latin America. The unit serves both on-site field verification and incoming inspection of newly installed revenue meters. Buyers should confirm with Beijing Gfuve Electronics whether the calibration software supports IEC 62053-22 three-phase active meter classes as well as local national variants. Packaging, Incoterms and commissioning support are not stated in the listing and require direct supplier clarification.

Beijing Gfuve Electronics Co., Ltd. is headquartered at 01117-8 Fortune Street, No.67 Chaoyang Road, Beijing 100025, China. The company is classified as an imported supplier tier with a harbor trust tier, indicating it is a registered Chinese entity on the platform with basic verification but no advanced trust signals. The response rate is recorded at 0.00% with an average response time of zero hours, which suggests either a new listing, a dormant account or a data collection gap rather than active non-response.

The supplier's product focus centres on electrical test and measurement equipment, specifically energy meter calibration instruments with portable, printer-integrated designs. The GF312B listing provides concrete technical data (accuracy classes, voltage range, harmonic capability, weight, IP rating) but omits commercial details such as MOQ, unit price, lead time, warranty terms and after-sales support coverage. Buyers should treat the technical specification as verified but negotiate all commercial and logistical terms directly with Beijing Gfuve Electronics before placing an order.
