3NH NH310 Portable Colorimeter

3NH NH310 Portable Colorimeter

The 3NH NH310 Portable Colorimeter is a high-precision, versatile instrument designed for color measurement across a wide range of materials and surfaces. With dual measuring apertures (Φ8mm and Φ4mm), advanced color space options, and high inter-instrument consistency, the NH310 is ideal for professional quality control in industries such as paint, plastic, textiles, and more. It is an upgraded version of the NH300, offering expanded functionality and improved repeatability, while maintaining portability and ease of use.

Features

• Dual aperture flexibility
  Equipped with interchangeable Φ8mm and Φ4mm measuring apertures to suit flat, concave, or textured surfaces.

• Advanced colorimetric capabilities
  Supports multiple color spaces (CIELab*, CIEXYZ, CIERGB, etc.) and color difference formulas including △E*ab, △E94, and △Ehunter for comprehensive color analysis.

• High repeatability and accuracy
  Ensures standard deviation within ΔEab 0.06 (based on 30 measurements of a standard white plate) and inter-instrument error ≤0.40 ΔEab.

• Versatile light source options
  Utilizes multiple illuminants (D65, D50, A) powered by LED blue light excitation for accurate simulation of various lighting conditions.

• Large storage and fast performance
  Capable of storing 100 standard references and 20,000 sample readings, with quick processing and easy data retrieval via USB.

• Portable and efficient
  Lightweight at 500g, powered by a 3.7V/3200mAh lithium battery supporting 3000+ measurements per charge, with full recharge in just 2 hours.

Application

• Paints and coatings
  Used to evaluate color consistency, brightness, and hue shifts in decorative and industrial coatings.

• Plastics and injection molding
  Ensures uniformity in colored resins, molded parts, and polymer surfaces.

• Textile and apparel manufacturing
  Validates dyeing results and shade matching for fabrics and garments.

• Printing and packaging
  Confirms precise reproduction of brand colors on paper, film, and packaging materials.

• Food and pharmaceuticals
  Monitors product appearance quality in compliance with visual standards.

• Research and quality control labs
  A dependable tool for R&D, color formulation, and standardization in labs and manufacturing units.
