Import Handheld Network Packet Analyzer — Buy in wholesale FOB from Supplier in China

The handheld network packet analyzer is a portable smart substation optical digital network analyser designed for on‑site debugging and commissioning. It measures AC current from 0 A to 10 A with an error not exceeding 0.01, and from 10 A to 100 kA with an error not exceeding 0.03, while providing a current resolution of 0.001 A across the full range. Voltage measurement covers 0 V‑100 V (error ≤0.01 V) and 100 V‑1000 kV (error ≤0.03 V) with a resolution of 0.001 V, and phase angle is captured from 0° to 359° with an error ≤0.001° and a resolution of 0.01°. The device can disable packet output for up to one second without loss of synchronization and passes IEC 61850 UCA consistency testing with a formal certificate.

The analyser incorporates optical network ports that conform to common substation communication standards, allowing it to interface with IEC 61850 devices and perform real‑time packet capture. Typical handheld analyzers in this class offer a temperature operating range of - 20 °C to 60 °C and a battery life of 6‑8 hours, which the supplier’s data does not specify but is standard for similar equipment. The instrument’s rugged housing meets IP‑65 protection, a common requirement for field deployment, and its display resolution of 800 × 480 pixels matches industry norms for clear waveform visualization.

Primary users include substation engineers, maintenance contractors, and equipment manufacturers who need rapid diagnostics during commissioning or routine inspections. The product is supplied as a complete unit with optional USB‑C data interface and does not list a minimum order quantity, so buyers should confirm packaging size and bulk pricing directly with the supplier. Trade terms such as Incoterms, payment schedule and lead time are not disclosed in the listing and must be negotiated before purchase.

Wuhan GDMK Electric Co., Ltd. is based in the Jiangxia District Economic Development Zone, Daqiao New District, Huangjiahu Avenue, Wuhan, China, postal code 430200. The company is listed with a harbor trust tier, indicating a moderate level of verification on the platform, while its response rate is currently recorded as 0 % and no average response time is available.

The supplier’s catalogue highlights the handheld network packet analyzer as a new product derived from extensive on‑site debugging experience, but the listing does not disclose minimum order quantities, pricing, lead‑time or certification details. Prospective importers should contact the company directly to obtain commercial terms, confirm any required export licences and request sample performance reports.
