3nh NetMetric Network Correction Software is a cloud-powered color measurement instrument calibration solution tailored for industrial color control scenarios. It is ideal for manufacturing enterprises operating multiple colorimeters or spectrophotometers, quality management settings with strict color consistency requirements, and environments requiring periodic instrument performance verification. The software is designed to resolve inter-departmental and cross-regional device discrepancies, as well as data errors resulting from performance degradation such as slight integrating sphere contamination, light source aging, and mechanical wear. Without returning instruments to the factory, users can significantly improve measurement accuracy in just 15 minutes per month. All data corrections are fully traceable, ensuring absolute color data accuracy.
Traditional factory recalibration typically takes several weeks, incurring high logistics and communication costs. The NetMetric software streamlines the recalibration workflow through a “Cloud + Edge” architecture:
Measure Standard Targets: Collect data using specified, matching standard color tiles.
Cloud Calculation: Upload measurement data; backend algorithms automatically generate dedicated calibration parameters.
Write to Instrument: Import calibration parameters into the instrument with a single click. Accuracy is restored on-site in 15 minutes without factory return.
Built on a cloud-based architecture, the NetMetric Network Correction System establishes a comprehensive instrument health management system through three functional modules:
Guided Workflows Lowering Professional Barriers. Deconstructs complex calibration procedures into clear, step-by-step visual guidance from calibration preparation to data validation. Operators can complete professional-grade calibrations without deep technical backgrounds, featuring traceable workflows and reliable results. With a wizard-style user interface, a complete calibration takes only 15 minutes per month, eliminating the need for on-site color engineers. Post-calibration, the software automatically generates a detailed report comparing pre- and post-calibration accuracy data.
Unified Digital Repository for Multiple Instruments. Every calibration record is automatically archived in the cloud, supporting retrieval, traceability, and management by instrument serial number or timestamp. This resolves the common industry pain point of “lost records after calibration.” Historical parameters can be re-imported into instruments, facilitating cross-departmental quality inspection tracking and batch maintenance across multiple devices. Supports one-click PDF calibration report export with traceable data, ready for client supply chain audits and compliance checks.
Traceable Reference Database for Authoritative Calibration Results. Provides standardized management of spectral reference data for standard color tiles used during calibration. It supports official QTX file imports, fully recording parameters such as wavelength and spectral reflectance for each set of data. Serving as the benchmark for instrument calibration, it ensures data accuracy and verifiable provenance throughout the calibration process.
