Does the sensor require flow rate for measurement?

No, the sensor uses the fluorescence principle which does not consume oxygen and has no flow rate limitation.

What is the power supply requirement?

The sensor requires a DC 6~12V power supply.

Is customization available for this product?

Yes, we offer OEM and ODM services, including customization from samples, designs, and flexible customization options.

AI-Powered supplier vetting

SummaryThe supplier demonstrates established product development and customization capabilities, including 3D design, multiple customization models, ODM/OEM services, SDK availability, and software proficiency in AutoCAD, Pro/E, and SolidWorks. Quality processes include documented inspection, complaint handling, corrective and preventive action procedures, and stated quality assurance. Production evidence includes two production lines, one million pH meter units annually, two quality inspectors, and lead times within 15 workdays in both peak and off-peak periods. Service coverage is comparatively limited: no overseas warehouse, showroom, agents, branches, or overseas service countries are reported, and there is no valid manufacturing-capacity contract with related subcontractors. R&D documentation available for audit is also lacking. Certification, financial credibility, and customer-case evidence are insufficiently documented in the provided information.

Supplier typeThe supplier operates an assembling line and two production lines, produces pH meters, and serves industrial process control, municipal water testing, environmental monitoring, laboratory, and portable instrument applications. The information supports classification as a manufacturer and assembler of measuring instruments, although no formal supplier-type designation is stated.

After-Sales capabilityThe supplier has documented procedures and records for corrective and preventive actions, customer complaints, supplier-service assessment, and finished-product inspection. However, it reports no overseas warehouse, showroom, agents, branches, or overseas service countries, indicating documented service processes but limited overseas service infrastructure.

R&D capabilityThe supplier reports new products during the past year, a professional R&D team, continuous innovation, more than 20 patents, ODM capability, SDK availability, and engineering proficiency in AutoCAD, Pro/E, and SolidWorks. Nevertheless, no design-input, output, review, verification, or validation documents were available for auditor review.

Production capacityProduction evidence includes two production lines, annual pH meter output of 1,000,000 pieces, in-stock capability, two quality assurance/QC inspectors, standardized finished-product inspection instructions, and lead times within 15 workdays in peak and off-peak seasons. A deficiency is that no valid manufacturing-capacity contract exists between the factory and related subcontractors.

Customization capabilityThe supplier explicitly provides 3D software design, customization from samples and designs, full, minor, and flexible customization, as well as ODM and OEM services. These repeated capabilities across design and R&D records provide clear evidence of broad customization support.
