Import 3-Phase Multifunction Electric Meter Calibrator — Buy in wholesale FOB from Supplier in China

The GF312V2 portable three-phase multifunction energy meter calibrator from Beijing Gfuve Electronics Co., Ltd. is a field-ready instrument designed for electric power departments, metrology bureaus, and electrical laboratories requiring on-site verification. It delivers accuracy classes of 0.05% and 0.1%, with phase voltage measurement spanning 30-560V and direct-connection current measurement from 0.01A to 10A. Clamp CT options extend current handling to 5A, 100A, 500A, 1000A, and 2000A. The unit runs on external 220V/110V, 50/60Hz power or an internal Li-Battery, and operates across ambient temperatures from -25C to +45C at relative humidity levels of 30% to 95%.

The calibrator measures active and reactive power and energy with direct-connection errors of 0.05% and 0.1% respectively, while clamp CT configurations introduce 0.2% to 0.5% error bands depending on range. Harmonic analysis covers the 2nd through 51st orders for both voltage and current channels. Phase angle resolution reaches 0.01 degrees across a 0-360 degree range, and frequency measurement resolves to 0.001Hz with 0.002Hz error across 45-65Hz. The 7-inch TFT colour display at 480x234 resolution renders vector diagrams, waveforms, and real-time data, while 5000-record internal storage plus USB/RS232 ports and optional external memory support comprehensive documentation workflows.

Typical buyers include grid operators, calibration laboratories, and electrical equipment manufacturers who require traceable field verification of energy meters and instrument transformers. The unit's wiring emulation and self-calibration functions reduce dependency on external reference standards during routine maintenance cycles. The 245 x 168 x 70mm form factor and 1.8kg weight suit deployment in substations and portable test rigs. Importers should confirm with Beijing Gfuve Electronics whether factory calibration certificates include CNAS accreditation or equivalent national metrology institute traceability, and whether clamp CTs ship as standard or require separate procurement.

Beijing Gfuve Electronics Co., Ltd. is located at 01117-8 Fortune Street, No.67 Chaoyang Road, Beijing 100025, China. The company is classified as an imported supplier tier with harbor trust status. The listing shows zero response rate and zero average response hours, which indicates the supplier has not established active communication patterns through the platform. No workforce size, annual revenue, or client references are stated in the available profile data.

The supplier's product range centres on electrical measurement and calibration equipment, with the GF312V2 representing a portable three-phase energy meter calibrator positioned for field use by power utilities and metrology agencies. The listing provides detailed technical parameters but omits information about manufacturing certifications, ISO quality management systems, or after-sales service infrastructure. Buyers should verify directly with Beijing Gfuve whether the company holds manufacturing licences for measuring instruments under Chinese national regulations, and whether export documentation includes customs commodity codes and applicable technical conformity marks.
