3nh CR3 Colorimeter (Advanced Edition; ΔE*ab 0.05)

3nh CR3 Colorimeter (Advanced Edition; ΔE*ab 0.05)

In manufacturing industries with strict color requirements, even a small micro-chromatic deviation can ruin an entire batch and cause losses of hundreds of millions of VND. Field QC engineers and color matching designers are always looking for a mobile color matching device: both pocket-sized for flexible mobility and achieving strict accuracy on par with lab benchtop instruments. The 3nh CR3 Smart Mini Colorimeter (Advanced Edition) is the perfect answer – an upgraded version featuring an extremely small Delta E*ab error below 0.05, redefining color control capability on a mini device.

Overview of the 3nh CR3 Smart Colorimeter (Advanced Edition)

The 3nh CR3 (Advanced Edition) is a premium handheld mini colorimeter developed by the 3nh brand based on a high-speed processing chip and a new-generation integrated optical sensor. The device utilizes the international standard d/8 optical geometric structure (diffuse illumination, 8-degree viewing angle), fully meeting the strict regulations of international CIE and ISO standards.

What makes the Advanced Edition (CR3) lead the mini segment lies in its measurement repeatability control capability. With a Delta E*ab error index below 0.05 (the average value after 30 measurements on a standard white tile), the CR3 delivers color quantification results with excellent stability, helping businesses confidently verify product quality right in the field.

Outstanding Features of the 3nh CR3 Advanced Edition

💡 Absolute Accuracy (Delta E*ab below 0.05) – The Supreme Standard of the Mini Segment

Equipped with an upgraded high-resolution matrix optical sensor system, the CR3 Advanced Edition is capable of capturing the smallest micro-chromatic changes on material surfaces. The repeatability error is strictly controlled to under 0.05 Delta E*ab, delivering objective and highly reliable measurement data, completely eliminating identification errors caused by subjective human eye perception.

💡 Smart Auto-Calibration upon Startup

Businesses no longer have to worry about technicians forgetting to calibrate the device before measuring, which leads to data deviations. The 3nh CR3 integrates a high-tech white calibration tile right inside its lens protective cap. Every time the device is turned on, it automatically executes an internal optical calibration process, ensuring the instrument is always in its most precise state.

💡 Universal Mobile App Connection – Smart Cloud Digitization

Via a high-speed wireless Bluetooth connection, the CR3 synchronizes perfectly with dedicated color management applications on Android and iOS operating systems. The mobile App unlocks versatile features:

• Automatic Electronic Color Code Lookup: Simply press the device and trigger a measurement on the sample surface; the App automatically checks spectral data and displays the closest matching color codes in international Pantone, RAL, and NCS libraries with an extremely high accuracy rate.
• Build Color Libraries on the Cloud: Supports creating and storing personal project color palettes (Color Cards) and instantly sharing digitized color data with colleagues or partners via Zalo, Email, or WeChat.

💡 Intuitive Pass/Fail Evaluation Directly on the Mini Screen

The CR3 Advanced Edition is equipped with a sharp industrial display screen directly on its body, allowing the instrument to operate independently exceptionally well without a smartphone connection. With a simple click, the device calculates the color difference index and instantly displays intuitive chromatic analysis results, helping workshop operators quickly screen defective parts directly on the production line.

💡 Mini, Fashionable, and Portable Ergonomic Design

With an ultra-lightweight profile and a refined compact cylindrical design, the CR2 offers maximum flexibility. Technicians can easily slip the device into a protective vest pocket, hook it to a lanyard, or carry it to on-site project surveys to professionally approve samples with clients effortlessly.
