AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company engaged in sensor, transmitter, and related instrument research, manufacturing, sales, and service. It reports ISO 9001-related certification, TS 16949 and ISO 20000 certifications, CE capability, ERP integration, three production lines, and documented procedures for supplier-service assessment, corrective actions, and complaint handling. It offers 3D design, ODM, and multiple customization models, but reports no new products during the past year, no SDK, and no OEM service for popular brands. Overseas service infrastructure is limited: no overseas warehouse, showroom, agent, or branch, and the stated overseas-service country count is zero. Financial records are referenced for recent years, but the provided slices do not disclose sufficient non-financial evidence to assess financial credibility. No customer cases are provided.

Supplier typeThe supplier is explicitly classified as a trading company. Its company description states that it conducts research, development, manufacturing, sales, and service for sensors, transmitters, and related instruments.

CertificationsThe supplier reports TS 16949, ISO 9001, and ISO 20000 certifications, along with an ISO 9001:2015 certificate and CE certification capability. These stated certifications provide explicit evidence of formal quality or management-system credentials.

After-Sales capabilityThe supplier reports documented and followed procedures for corrective and preventive actions and customer complaints. However, it has no overseas warehouse, showroom, agent, or branch, and the stated overseas-service country count is zero, indicating documented service processes but limited overseas service infrastructure.

Production capacityThe company describes itself as involved in manufacturing sensors and related instruments and reports operating three production lines. It also provides a stated water-level-sensor output figure, but the overall production scale and broader capacity are not sufficiently detailed for a complete capability assessment.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, flexible customization, and ODM services. This is direct evidence of broad product customization capability.

Product Q&A

Q:Does this sensor require a dedicated controller or meter?

No. The GEC-COD485 is an intelligent digital sensor with a built-in signal processing unit that outputs a digital signal directly. You only need to provide power and read the data via the RS485 interface, greatly simplifying the system configuration.

Q:How do I calibrate the sensor?

The sensor supports multi-point calibration. You need to use standard solutions of known concentration and follow the instructions in the manual to send calibration commands via compatible software or a Modbus-enabled device. We provide detailed calibration guidelines.

Q:How does the auto-cleaning function work?

The sensor features an integrated auto-cleaning device that prevents fouling on the optical window. This reduces manual maintenance and ensures long-term stability of the readings.

Q:Can the cable length be customized?

Yes. The standard configuration is a 5-meter cable. If you require a longer or specific length, please state your needs during inquiry or ordering, and we can customize it for you.

Q:What is the warranty period for this sensor?

We provide a one-year warranty for this sensor, along with lifelong after-sales service support.
