| 01 | Product Category and Application Fit | The manufacturer should have a proven product line matching the intended use, such as industrial condition monitoring, environmental monitoring, laboratory monitoring, healthcare monitoring, or security monitoring. | Product specifications, application cases, operating-temperature range, measurement range, sampling rate, and supported installation methods. | 15% | Must Verify |
| 02 | Quality Management System | A documented quality management system based on ISO 9001 is a strong baseline for general monitoring equipment. Medical-device projects may require ISO 13485 depending on the product and market. | Valid certificate, certification scope, issuing body, expiry date, corrective-action records, and internal quality-control procedures. | 12% | Check Validity |
| 03 | Regulatory and Market Compliance | Compliance must match the destination market and product category. Common requirements may include RoHS, electromagnetic compatibility testing, electrical safety testing, and applicable medical-device regulations. | Test reports, declarations of conformity, technical files, product labels, user manuals, and market-specific registration records where applicable. | 15% | Must Verify |
| 04 | Measurement Accuracy and Calibration | Accuracy, repeatability, resolution, drift, response time, and calibration interval should be stated for every measured parameter and operating condition. | Calibration certificates, uncertainty data, inspection reports, reference-instrument details, and sample test results from an independent laboratory when necessary. | 15% | Core Criterion |
| 05 | Connectivity and Data Compatibility | The device should support the communication method required by the project, such as Ethernet, Wi-Fi, cellular communication, RS-485, Modbus, MQTT, or an equivalent documented protocol. | Communication protocol documentation, API references, integration guides, gateway specifications, data-export formats, and a live integration demonstration. | 10% | Test Required |
| 06 | Environmental Protection and Reliability | The enclosure rating, operating temperature, humidity tolerance, vibration resistance, ingress protection, and expected service life must suit the installation environment. | Environmental test reports, ingress-protection test results, operating-limit specifications, component derating policy, and reliability or burn-in records. | 10% | Site Dependent |
| 07 | Cybersecurity and Data Protection | Network-connected equipment should use access control, secure account management, encrypted communication where appropriate, firmware-update procedures, and a vulnerability-response process. | Security architecture, password policy, firmware signing or update method, vulnerability disclosure procedure, penetration-test summary, and data-retention policy. | 10% | Increasing Priority |
| 08 | Production Capacity and Delivery Control | The supplier should demonstrate stable production capacity, traceable serial-number management, component availability, and a delivery schedule supported by realistic manufacturing data. | Production lead time, monthly capacity range, production-flow description, capacity-reservation terms, bill-of-materials risk review, and sample order history. | 8% | Commercial Review |
| 09 | Customization and Engineering Support | For OEM or project deployments, the manufacturer should be able to support firmware configuration, enclosure changes, sensor selection, language localization, communication integration, and pilot testing. | Engineering-team profile, customization workflow, prototype timeline, change-control procedure, non-recurring engineering quotation, and pilot-project plan. | 3% | Project Specific |
| 10 | Warranty, Service, and Total Cost of Ownership | Selection should consider warranty length, replacement policy, spare-parts availability, remote support, calibration cost, software fees, training, and long-term maintenance—not only the initial unit price. | Warranty terms, service-level agreement, response time, spare-parts list, repair process, software subscription terms, calibration pricing, and five-year cost estimate. | 2% | Cost Review |
