About Us

Shanghai Cuidun(Cuizex) Metrology Technology Co., Ltd. is dedicated to providing high-precision measurement instruments, reliable data acquisition equipment, and future-oriented digital and compliance solutions for the global industrial sector.

Quidun does not offer certification services or generic compliance software; we focus solely on the most challenging aspect of equipment export: compiling instrumentation, control systems, calibration, and software component information into verifiable evidence packages suitable for audits, inspections, and manufacturer technical documentation. We ensure export equipment and industrial projects possess verifiable documentation prior to audits.

Post-2026, CBAM, green hydrogen certification, CCUS MRV, and multinational supply chain ESG audits will elevate “on-site data credibility” to a transactional prerequisite. We structure foundational measurement systems into verifiable technical evidence frameworks for factory compliance, achieving rationalized compliance.

The cuizex Three-Step Method: Diagnosis → Upgrade → Forensics

Complex industrial machinery with multiple interconnected hoses and pipes, featuring control panels and metallic cylinders. The setup includes blue and yellow hoses, with metallic fastenings and electrical components.

STEP 1: Compliance Assessment
Identify key measurement points throughout the plant and use the GUM method to create an uncertainty budget and a regulatory gap matrix.

A large industrial factory setting with heavy machinery and equipment. Several workers are engaged with the machines, appearing to be operating or maintaining them. The scene is dimly lit, with numerous overhead lights leading into the distance. The machinery is robust and complex, indicating a heavy manufacturing process.

Step 2: Hardware Upgrade
Based on operating conditions, pipe diameter, pressure, and medium characteristics, we provide recommendations for selection, supply, installation, and commissioning.

STEP 3: Submission of Evidence
Generate the calibration certificate chain, IQ/OQ documentation, technical data sheets, and a verifier-ready Evidence Pack.
