The 3NH NR145 Precision Colorimeter is a high-performance device designed for precise color measurement and quality control across multiple industries. With its 45°/0° optical geometry, ergonomic design, and intuitive operation, it provides reliable and repeatable color data for professionals in printing, plastics, coatings, textiles, and beyond. The NR145 ensures superior accuracy, thanks to its advanced LED blue light excitation technology and robust internal components.

Features

• High-precision optical system
  Utilizes 45°/0° illuminating/viewing geometry to minimize gloss influence, making it ideal for consistent measurement on textured or glossy surfaces.

• Wide measurement aperture
  The Φ8mm measuring aperture ensures excellent performance on larger or uneven sample areas, reducing variability in readings.

• Dual positioning modes
  Offers both illuminating locating and cross locating methods, helping users align the device precisely for accurate color sampling.

• Comprehensive data storage
  Capable of saving 100 standard reference colors and up to 20,000 sample measurements for robust data tracking and management.

• Efficient power system
  Powered by a rechargeable 3.7V lithium-ion battery with long life and fast 8-hour full charge, suitable for extended field or lab work.

• Optional software and printing
  Compatible with CQCS3 software for data analysis and quality control, and supports optional miniature thermal printer for immediate results.

Application

• Coatings and paint industry
  Used for evaluating the consistency and color difference in paint batches, pigment formulation, and final coatings.

• Plastics and polymers
  Ensures color conformity in molded components, sheets, and films across production lots.

• Textile and apparel production
  Helps maintain color consistency in fabrics, yarns, and garments across dye lots and suppliers.

• Packaging and printing
  Assists in matching brand color standards on cartons, labels, and printed materials.

• Automotive components
  Ideal for matching interior and exterior parts for consistent appearance and aesthetics.

• Laboratory and research environments
  Supports R&D teams in color formulation, comparative testing, and teaching color science principles.
