The GF312B2 from Beijing Gfuve Electronics Co., Ltd. is a portable three-phase reference meter built to Class 0.02 accuracy for laboratory calibration and on-site verification of energy measurement systems. It incorporates a 24-bit A/D converter to ensure stable, high-resolution sampling across variable load conditions, and ships with compatibility for multiple clamp-on current transformer configurations plus smart optical sampler inputs. The ABS housing protects internal electronics during field transport, while copper CT coils maintain low-loss signal transfer from primary conductors to the measurement core.
This instrument targets metrology departments, utility metering laboratories, watt-hour meter manufacturers, and third-party certification bodies requiring traceable standards for power quality analysis. The clamp-on CT capability eliminates the need to break primary circuits during verification, reducing downtime in live substations and industrial switchgear. Standard applications include energy audit compliance testing, incoming inspection of installed meters, and R&D validation for new metering products before regulatory approval.
Buyers should confirm with Beijing Gfuve Electronics Co., Ltd. which clamp-on CT ratios and optical sampler models are bundled or available as accessories, since compatibility ranges affect field deployment. Typical export configuration includes calibrated test leads and a transport case, though buyers should verify Incoterms and whether on-site commissioning support is offered. Response rate data is currently unavailable, so direct enquiry is recommended for lead time and certification documentation such as ISO 17025 traceability certificates.

Before placing an order with Beijing Gfuve Electronics Co., Ltd., verify that the clamp-on CT set covers your actual primary current ranges and conductor diameters, as mismatch will prevent safe installation. Request a current calibration certificate with CNAS or equivalent accreditation body logo, and confirm that the certificate date is within twelve months of planned commissioning. Ask whether firmware updates and English-language operating software are provided without charge, and whether telephone or video technical support is available during initial setup.
Logistics and lead time must be confirmed directly with the supplier, as no stated production or delivery schedule is available in the source data. Discuss Incoterms that split risk appropriately: EXW Beijing leaves all export formalities to you, while FCA or CIP may simplify door-to-door arrangements if the supplier has forwarding experience. Payment terms typical for first transactions with Chinese electronics suppliers run 30 percent deposit with balance against scanned bill of lading, though Beijing Gfuve Electronics Co., Ltd. may propose alternatives. Insist on detailed pro-forma invoice breakdown including harmonised system code for the meter and each accessory to pre-empt customs valuation disputes.
Upon arrival, inspect the shipment for transit damage to the ABS housing and calibration seals before accepting delivery. Cross-check the serial number against the calibration certificate and request that the supplier provides pre-shipment photos of the meter display showing self-test pass results. For critical metrology use, consider engaging an independent third-party inspection agency in Beijing to witness factory calibration and packing. Retain all documentation, including packing list, commercial invoice, and certificate of origin, to support warranty claims and future recalibration scheduling with Beijing Gfuve Electronics Co., Ltd. or your local standards laboratory.
