ColorReader CR2 Portable Color Reader
ColorReader CR2 | Portable Color Measurement, App Color-Card Search and Color Management
ColorReader CR2 is a portable color tool for quick on-site color reading, color-difference assessment, and color-card search. Stand-alone operation, a mobile app, and computer software help users review sample color values, assess differences, simulate colors, and find similar shades.
CR2 combines a compact colorimeter with a mobile color-reading app. Its multifunction smart button, non-contact automatic white-tile calibration, app-based color-card search, and color-difference management support color comparison in plastics, electronics, paints and inks, printing, textiles, leather, paper, automotive, medical, cosmetics, and food applications. Confirm suitability based on sample material and surface, measurement area, app functions, and quality-control workflow.
ColorReader CR2 Key Features
Real-time measurement, automatic calibration, an app-based color-card database, and portable operation support quick color checks and on-site communication.
Real-Time Color Measurement
CR2 quickly reads sample color data. Published specifications state repeatability below 0.08 and display resolution of 0.01. It suits applications that need quick on-site color data and preliminary color-difference assessment.
Actual measurement performance depends on sample surface condition, measurement location, lighting, operation, and internal quality-control procedures.
Non-Contact Automatic Calibration
CR2 uses non-contact automatic black-and-white calibration to reduce direct contamination of the white calibration tile during measurement and help maintain stable daily operation.
For organizations with a quality-control SOP, establish pre-measurement checks, calibration intervals, white-tile storage, and equipment-management procedures to maintain consistent data.
Multifunction Smart Button
The multifunction button supports basic measurement settings and review of stored data without a phone or computer, making CR2 convenient for quick field operation.
With the mobile app or computer software, users can also view color-difference charts, color simulations, manage data, and compare colors. Available functions depend on the software version and workflow.
Portable Design and Rechargeable Lithium Battery
The lightweight CR2 fits in a pocket or tool bag for quick color checks at customer sites, showrooms, sample rooms, production areas, or offices.
CR2 uses a Type-C charging port and a rechargeable lithium battery. Published information states approximately 12,000 measurements per full charge. Actual battery life depends on screen brightness, Bluetooth use, measurement frequency, and environment.
Industrial-Grade MCU and Bluetooth 5.0
CR2 uses an industrial-grade MCU and supports Bluetooth 5.0 for viewing data, analyzing colors, and searching color cards through the mobile app.
For integration with an internal database, reporting system, or custom workflow, have an engineer assess the implementation based on actual requirements.
App Color-Card Database and Color-Data Management
The CR2 app can display sample colorimetric values, color differences and charts, pass/fail results, color simulations, color cast, and reflectance data to improve on-site checks and data management.
The app can build a personal color database and search multi-color card sets for similar shades, reducing the need to carry bulky color cards. Use results for communication and preliminary comparison; make final decisions based on the sample and approval process.
Color Tasks Supported by CR2
Color Reading
Quickly read sample colors and obtain colorimetric and related color data.
Color-Difference Assessment
View color-difference values and charts, along with pass/fail results.
Color-Card Search
Search an app-based color-card database for similar shades to support matching and customer communication.
Data Management
Build a color database for sample records, comparison, and follow-up.
Where to Consider ColorReader CR2
Design Proofing
For quick color checks on design, print, packaging, coatings, and display materials.
On-Site Color Matching
Quickly read colors and search similar color cards at customer sites, showrooms, or job sites.
Sample Comparison
For preliminary color-difference checks among supplier samples, customer samples, standards, and trial samples.
Basic Quality Control
Use as a preliminary color-check tool to quickly assess differences and guide discussions.
Selection and Use Notes
ColorReader CR2 supports color reading, color-card search, on-site communication, and preliminary color-difference assessment. For glossy, transparent, translucent, heavily textured, fluorescent, or uneven samples, confirm the measurement location, lighting, sample surface, and internal criteria. For full spectral data, multi-illuminant analysis, SCI/SCE switching, or formal supply-chain acceptance, consider a handheld spectrophotometer.
