AI-Powered supplier vetting

SummaryThe supplier is a combined manufacturing and trading entity focused on food thermometers and intelligent or electronic measuring instruments. It reports extensive customization and ODM capability, recent new-product activity, OEM service for well-known brands, and production of 5,000,000 thermometers annually across three production lines. Quality controls include documented finished-product inspection instructions, although only two quality assurance and quality control inspectors are specifically reported in one slice and certification of supplier management systems is listed as NIL. The supplier has export experience, with 90% of sales reportedly from exports and primary markets in Europe and North America. Manufacturing contracts and in-stock capability are available, but no overseas warehouse or showroom is reported. Service-management weaknesses include no written procedures or records for service assessment, corrective actions, or complaint handling. Financial information is referenced for...

Supplier typeThe supplier is identified as a combined company, with a business scope covering manufacturing of intelligent instruments and electronic measuring instruments, along with sales and retail of Class I and Class II medical devices. This supports classification as a combined manufacturing and commercial supplier rather than a purely trading entity.

CertificationsThe supplier management-system certification field is explicitly listed as NIL. Although finished-product inspection instructions are documented and uniformly followed, the provided evidence does not show possession of management-system certifications.

After-Sales capabilityThe supplier reports no written procedures or records for assessing service capability, corrective and preventive actions, or effective customer-complaint handling. It does have manufacturing contracts with associated subcontractors and in-stock capability, but no overseas warehouse or showroom service is available.

R&D capabilityThe supplier reports new products during the past year, ODM service, and two years of total R&D-engineer experience. It also reports no available SDK, so the evidence supports product-development capability but not software-development integration capability.

Production capacityThe supplier reports three production lines, annual thermometer output of 5,000,000 pieces, in-stock capability, valid manufacturing contracts with associated subcontractors, and a one-month average lead time in both peak and off-season. These data indicate established production capacity, although the separately stated number of quality assurance and quality control inspectors is two.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also provides ODM services, directly supporting broad customization and original-design capability.

Product Q&A

Q:Q1: What liquids can this portable tuning fork meter measure?

A1: It supports ethanol, ammonia, methanol, sulfuric acid, hydrochloric acid, sodium hydroxide, urea, glycol, sucrose(Brix), hydrogen peroxide. Custom liquid formula calibration is available.

Q:Q2: Why are measured values unstable?

A2: 1. Clean residual liquid or bubbles on tuning fork surface; 2. Increase damping value in menu; 3. Avoid strong vibration, frequency converter interference around test area; 4. Ensure full liquid immersion of fork body.

Q:Q3: Can the probe resist strong acid and alkali corrosion?

A3: Standard wetted part is 316L stainless steel; optional Hastelloy C or Zirconium material for severe corrosive acid/alkali working conditions, check compatibility table before use.

Q:Q4: How long can the built-in battery last after full charge?

A4: Continuous working time reaches 8 hours; auto power-off function can be set to save power, charge timely when low voltage prompts.

Q:Q5: Why is the test error relatively large?

A5: 1. Sensor fork body stained or corroded; 2. No water calibration after long-time storage/transport; 3. Air bubbles attached on fork surface; 4. Wrong liquid mode selected on the meter; 5. Mixed multi-component liquid without customized calibration formula.
