3nh NR20XE Precision Colorimeter (45°/0°; Φ20mm)

3nh NR20XE Precision Colorimeter (45°/0°; Φ20mm)

In industrial color quality control processes, conventional colorimeters with small measuring apertures (Φ4mm or Φ8mm) are often helpless or face major measurement errors when dealing with non-uniform surfaces. Examples include large-weave textiles, textured leather surfaces, agricultural grains, foodstuffs, or brushed metal surfaces. When a small measuring aperture is placed on these materials, the light casts uneven shadows and is captured inconsistently, leading to continuous data drift. The 3nh NR20XE precision colorimeter was developed with an expanded aperture of up to Φ20mm and a standard 45/0 optical geometry, providing an exceptionally stable and accurate color quantification solution for special materials.

Overview of the 3nh NR20XE Precision Colorimeter

The 3nh NR20XE is a high-performance handheld colorimeter from 3nh, specifically engineered and manufactured to address color measurement challenges on rough, textured, or loose granular surfaces. The device utilizes an internationally standardized 45/0 optical geometric structure (45-degree circumferential oblique illumination and 0-degree perpendicular signal reception), fully satisfying the strict regulations of CIE, ISO, and ASTM standards.

The core advantage that allows the NR20XE to lead in measuring rough materials is its ultra-wide aperture contact area. By averaging the light energy over a large surface area, the device automatically eliminates local errors caused by surface irregularities or material textures, accurately reflecting the overall color exactly how the human eye perceives it from a natural distance.

Key Features of the 3nh NR20XE

💡 Ultra-Large Φ20mm Measuring Aperture – The Nemesis of Rough and Textured Surfaces

The most valuable aspect of the NR20XE is its measuring aperture size of up to Φ20mm (the largest among handheld colorimeters in its segment). The large measuring area allows the device to cover more fabric weaves, color grains, or textured patterns in a single press. Consequently, the returned data represents an accurate average value for the entire surface, completely eliminating data variance caused by placing the device on different irregular spots.

💡 Standard 45/0 Optical Geometry – Eliminating Matte Gloss and Shadowing Errors

Utilizing the 45/0 geometric structure, the NR20XE provides uniform illumination from a 45-degree angle and only captures true diffused light at a perpendicular 0-degree angle to the surface. This technology completely isolates the intrinsic color factor from interferences caused by surface gloss or shadowing effects from rough textures, delivering color matching results with maximum compatibility to real-world visual perception.

💡 Integrated Optical Path for Outstanding Repeatability

Even when measuring challenging materials, the NR20XE maintains remarkable stability due to its optimized optical path. Measurement repeatability error between consecutive readings is controlled at an extremely low level, establishing a reliable digital data foundation for businesses to approve outgoing product quality.

💡 Intuitive Display Interface and Ultra-Fast Pass/Fail Evaluation

The sharp industrial LCD screen displays results just 1 second after pressing the button:

• Common international color coordinate systems: CIE Lab, XYZ, LCh…
• Standard color difference index: Delta E*ab.
• Smart Pass/Fail tolerance warning mode: The device automatically references the measured sample against the standard sample according to the pre-set tolerance range, instantly displaying visual results to help shop-floor operators filter out defective products directly on the line.

💡 Deep PC Software Connectivity and Large Data Storage

Via a USB data transfer port, the NR20XE synchronizes data flawlessly with professional PC-based color management software. The system supports enterprises in storing thousands of standard sample datasets, managing digital color libraries, plotting shade variations over time, and automatically exporting professional quality control reports (QC Reports) to send to major clients.
