AI-Powered supplier vetting

SummaryThe supplier is a technology-driven enterprise integrating R&D, production, sales, and after-sales service, offering electrical testing equipment, specialized tools, meters, and related products. It reports new products within the past year, ODM capability, broad customization options, and OEM service for well-known brands. Overseas service is stated for Vietnam and Russia, including installation, debugging, maintenance, repair, and training, but the supplier has no overseas warehouses, showrooms, agents, or branches and has not participated in offline trade shows. Quality assurance and raw-material traceability are reported, while several service-control procedures lack written records. Financial information is inconsistent and insufficient for assessment.

Supplier typeThe supplier identifies as a technology-driven enterprise integrating R&D, production, sales, and after-sales service. Its listed products include electrical tools, intelligent meters, energy measurement equipment, fault-location and cable-testing equipment, and specialized instruments, indicating a manufacturer-oriented technology supplier.

After-Sales capabilityThe supplier states that it provides after-sales service and offers installation, debugging, maintenance, repair, and training in Vietnam and Russia. However, it has no overseas warehouse, showroom, agent, or branch, has not participated in offline trade shows, and its complaint-handling and service corrective-action procedures have no written records, limiting evidence of formal service execution controls.

R&D capabilityThe supplier reports R&D capability, new products within the past year, ODM services, and integration of R&D with production and after-sales service. It does not have an available SDK, but the available evidence still explicitly supports product-development capability.

Production capacityThe supplier is described as integrating production with R&D, sales, and after-sales service, and it lists a broad product range including tools, meters, and testing equipment. Quality assurance and raw-material traceability are reported, but the slices do not provide production capacity, factory scale, or output data.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM service, providing direct evidence of broad customization capability.

Product Q&A

Q:What are the main features of the handheld design?

The host is a handheld terminal that is small, light, dust-proof, and anti-corrosion, making it easy to carry for on-site testing.

Q:How does the device handle voltage reference?

It supports wired synchronization with voltage or software calculation without voltage. Optional modes include using phase B voltage or an electric field intensity sensor.

Q:Can the measurement ranges be customized?

Yes, the leakage current, resistive current, capacitive current, and voltage ranges are extensible. The standard leakage current is 0-20mA and voltage is 30-250V.

Q:What data export and control options are available?

The device supports U disk export, Bluetooth (BT) control via an Android APP, and data storage with protection during power-off.

Q:Is the device safe to use on charged arresters?

Yes, it is compatible with both charged and uncharged arresters. The internal voltage does not exceed 8.4V, and sensors are completely isolated.
