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:How many energy meters can be verified simultaneously?

The TD3650 supports simultaneous verification of 3 to 16 three-phase energy meters with the same voltage/current range but different meter constants.

Q:What is the measurement accuracy of the TD3650?

The device offers high precision with Class 0.02 or Class 0.05 accuracy for voltage, current, and power measurements.

Q:Does the system support harmonic testing?

Yes, it supports harmonic output from the 2nd to 63rd order at 50/60 Hz, programmable harmonic content/phase, and built-in high-order harmonic test schemes.

Q:What is the minimum current output capability?

The minimum current output is as low as 0.2 mA, allowing for precise starting current tests.

Q:Is the verification process automatic?

Yes, the professional verification software supports semi-automatic or fully automatic verification, including data management, error curve drawing, and certificate export.
