Basic color quality control standards for multiple industries


A colorimeter is a precision instrument for measuring color differences of objects and serves multiple vital functions. In industrial production, colorimeters are primarily deployed for quality control to guarantee consistent product color. For industries such as coatings, plastics, textiles and printing, a colorimeter can accurately quantify the color difference between test samples and reference standards, ensuring the color of every production batch stays within acceptable tolerance ranges.

3nh COLORIMER deliver reliable build quality and exceptional precision, providing enterprises with cost-effective and traceable color quality control measurements.

Equipped with multiple measuring apertures, 3nh colorimeters are capable of measuring reflected color and color difference across a wide range of industrial sectors. They are widely used for color quality control in compounding, food, raw materials and finished products.

    nr145_applications


For samples with irregular or uneven surface textures such as granules, coffee, fabrics, wood, stones and bricks, the PS808C Spectrocolorimeter is your ideal solution. Featuring a unique 50 mm large aperture, it is perfectly suited for these types of samples. Without this instrument, operators would have to manually take multiple measurements and calculate averages to obtain representative and repeatable data.

Colorimeter vs Spectrophotometer for Textile QC 

For textile quality control, a spectrophotometer is always the better choice instead of a basic colorimeter.

Key Reasons

  1. Spectrophotometer captures full spectral data, handles dyed fabric, printed textiles, yarn, woven and knitted materials with complex color and texture.

  2. Supports SCI/SCE, metamerism test, fastness comparison and batch color consistency inspection.

  3. Higher accuracy and better inter-instrument agreement, perfect for factory mass production and customer color approval.

  4. Basic colorimeters only show simple color difference data, easily affected by fabric texture, rough surface and lighting, with poor stability for textiles.

3nh Recommended Models

  • TS7700 / TS8560: High-precision, ideal for textile lab QC, color matching and raw material incoming inspection.

  • NR60CP / NS800: Cost-effective option for daily production line routine color checking.


Always a pre-production sample before mass production; Always final Inspection before shipment;
