3nh NR145 Precision Colorimeter (45°/0°; Φ8mm)

3nh NR145 Precision Colorimeter (45°/0°; Φ8mm)

In mid-range industrial manufacturing and processing workflows, maintaining color consistency between incoming and outgoing production batches is a prerequisite to ensure product quality. However, conventional colorimeters utilizing an integrating sphere structure (d/8) sometimes face significant limitations when measuring surfaces with fluctuating gloss levels or textured/matte surfaces, leading to results that do not match human visual perception. The 3nh NR145 precision colorimeter stands out as the optimal solution—a handheld device implementing the 45/0 optical geometry standard in the printing and coating industries, helping enterprises digitize colors accurately at an extremely economical investment cost.

Overview of the 3nh NR145 Precision Colorimeter

The 3nh NR145 is a specialized handheld colorimeter perfectly optimized by the 3nh brand for mobile testing capabilities directly across factories, warehouses, and QC departments. The device utilizes an internationally standardized 45/0 optical geometric structure (45-degree oblique illumination and 0-degree perpendicular signal reception), fully satisfying the strict regulations of CIE, ISO, and ASTM standards.

The most significant distinction that allows the NR145 to achieve outstanding stability within the budget segment lies in its rigorously engineered optical path. By simulating the natural viewing angle of the human eye when evaluating color, the device eliminates measurement errors caused by surface gloss effects, delivering color matching results with exceptionally high compatibility with real-world visual perception.

Key Features of the 3nh NR145

💡 Standard 45/0 Optical Geometry – Eliminating Gloss-Induced Errors

Unlike diffused sphere structures that can be easily misled by matte gloss, the 45/0 geometry of the NR145 allows the device to analyze color independently. When light illuminates the surface at a 45-degree angle, specular reflection rays are eliminated, and the device only captures true diffused light at 0 degrees. This technology is particularly optimal for textured surfaces, matte finishes, woven fabrics, or coating films with continuously changing gloss levels.

💡 Common Φ8mm Measuring Aperture and Intuitive Positioning Design

The NR145 is equipped with an industry-standard flat measuring aperture with a Φ8mm diameter, which is the golden size suitable for the vast majority of industrial manufacturing material samples. The flat aperture design allows the device to fit completely flush against large, flat product surfaces, eliminating external stray light interference. Combined with a clearly defined illuminated positioning spot, technicians can easily align the aperture with the exact area to be checked.

💡 Integrated Optical Path for Highly Stable Measurements

The device applies 3nh’s proprietary optical path simulation technology, which enhances its capability to collect stable light across multiple consecutive tests. Measurement repeatability error is controlled at an extremely micro level, ensuring maximum objectivity of the data data recorded on the production line.

💡 Rich Color Spaces and Ultra-Fast Pass/Fail Evaluation

With a single gentle button press taking less than 1 second, the sharp LCD display of the NR145 immediately presents intuitive results:

• Popular color coordinate systems: CIE Lab, XYZ, LCh…
• Industry-standard color difference index: Delta E*ab.
• Smart tolerance warning mode: Automatically compares the measured sample with the standard sample and instantly displays a Pass or Fail result based on the allowable tolerance range, helping shop-floor operators rapidly screen for defective parts directly on the line.

💡 Professional PC Software Connectivity

Via a USB data transfer port, the NR145 effortlessly synchronizes data with the professional CQCS PC-based color management software. The software supports businesses in storing thousands of standard sample datasets, tracking shade variation trend charts across production batches, and automatically exporting professional quality control reports (QC Reports) in PDF/Excel formats to send to major partners.

Practical Applications of the 3nh NR145

Thanks to its signature 45/0 geometric structure and highly reasonable investment cost, the 3nh NR145 precision colorimeter is widely applied in:

• Printing & Paper Packaging Industry: Checking color deviations of printing ink on corrugated cartons, flat decal labels, and matte paper packaging, ensuring absolute compliance with brand identity logo colors according to real human eye perception.
• Paint & Thin-Film Coating Industry: Rapidly measuring color variations of powder coatings, wall paint, and protective finishes on aluminum profiles or mechanical components with slightly rough surfaces.
• Textile & Leather Industry: Evaluating color quality, color fastness, and color consistency between flat dyed fabric rolls, shoe leather, or synthetic leather (simili) with embossed surface textures.
• Plastic & Rubber Processing Industry: Controlling the color uniformity of household molded plastic products and electronic equipment components featuring matte, anti-fingerprint surfaces.
