AI-Powered supplier vetting

SummaryTunkia Co., Ltd. is identified as a China-based manufacturer established in 2006, with 363 employees and an 8,000 m² manufacturing plant. Its stated products include magnetic and electrical measurement equipment, gaussmeters, and multifunction calibrators. The supplier reports ISO9001, ISO14001, and ISO45001 certifications, nine production lines, 120 years of combined R&D engineer experience, and 11–20 quality-control staff. It serves domestic and overseas markets, with exports representing 21%–30% of sales and reported one-month lead times in both off-peak and peak seasons. Evidence supports manufacturing scale, certification coverage, and technical capability. However, the provided information does not sufficiently establish after-sales service, financial credibility, customization capability, or a broad customer track record.

Supplier typeThe supplier is explicitly classified as a manufacturer, while the associated company information also describes the company nature as a trading company. Its 8,000 m² plant and manufacturing-related business activities support that it operates manufacturing capabilities, although the supplied classifications are not fully consistent.

CertificationsThe supplier reports ISO9001:2015, ISO14001:2015, and ISO45001:2016 management-system certificates, plus other unspecified certifications. This is explicit evidence of multiple quality, environmental, and occupational-health-and-safety certifications.

R&D capabilityThe supplier’s product scope includes magnetic measurement, electrical measurement, gaussmeters, and multifunction calibrators, and it reports 120 years of total R&D engineer experience. These details support technical and product-development capability, although no patent, new-product, or R&D investment data is provided.

Production capacityThe supplier reports an 8,000 m² manufacturing plant, 363 employees, nine production lines, and one-month lead times in both off-peak and peak seasons. These figures provide explicit evidence of established production capacity and stated delivery capability.

Product Q&A

Q:What is the difference between TK4860E-S and TK4860E-T?

The TK4860E-S is a single-phase model with a built-in 8kW load that does not support expansion. The TK4860E-T is a three-phase model that also has a built-in 8kW load but supports cascading with external three-phase 45kW resistive loads or electric vehicles.

Q:What is the measurement accuracy of the device?

The device offers Class 0.05 and Class 0.1 accuracy options. It features ms-level energy refresh speed to improve measurement accuracy of accumulated electric energy.

Q:Can the device test clock time errors?

Yes, the device has a clock verification function with real-time clock display and satellite timing, allowing it to complete the clock time error test of the charger.

Q:What safety protections are included?

The equipment is equipped with overvoltage protection, overcurrent protection, abnormal wind speed protection, and an emergency stop switch to ensure safety during operation.

Q:How is the device operated?

The instrument is operated through a wireless tablet, which allows users to save on-site information by taking photos and complete automatic testing. It also has its own display screen for direct working error testing.
