FAQs About TS4020 Benchtop Spectrophotometers

True color in chemistry is the color seen in a solution or compound in standardized conditions. It depends on electronic transitions in molecules, specifically absorption of a particular wavelength of light, and this depends on the structure of the compound.

Who are we? Threenh Technology: 22-Year Professional Color Measurement Solution Provider

Integrating research and development, design, production, marketing, and sales, the company takes technological innovation as its core and is committed to providing global customers with high-precision and intelligent testing instruments as well as professional solutions.


A colorimeter is sufficient for basic, routine color checks, while a spectrophotometer is needed for precise, comprehensive color analysis—here’s the clear breakdown:

When a Colorimeter is Sufficient

  1. Simple color matching needs: Ideal for checking if a sample matches a predefined standard (e.g., basic paint batches, plastic parts with solid colors).

  2. Consistent lighting conditions: Works well when measurements are done under fixed, standard light sources (no need to account for varied light effects).

  3. Cost-sensitive, high-volume tasks: Perfect for production lines requiring fast, low-cost color checks without advanced data analysis.

When to Use a Spectrophotometer

  1. Precise color quantification: Necessary for measuring Lab values (lightness, red-green, yellow-blue axes) or detecting subtle color deviations (critical for automotive coatings, high-end textiles).

  2. Complex color analysis: Required for metallic/pearlescent finishes, transparent materials, or samples with gloss/texture variations.

  3. Compliance and documentation: Essential when precise color data (spectral curves) is needed for quality audits, regulatory compliance, or brand color standardization.

When detecting color differences, the first factors to consider when selecting a light source include its stability, directionality, lifespan, and the effectiveness of the ultimately obtained spectral curve. The illuminant of a colorimeter is a fixed bulb, such as a tungsten lamp，LED light or a long-life xenon lamp. However, for the same color sample, the results displayed by the instrument vary under different light sources. This is because different light sources cause different absorption and reflection of light on the sample, leading to differences in how both the human eye and the instrument perceive the color. 

In general, the D65 light source is used in the application of coil steel inks for construction. The D65 light source is equivalent to average daylight. Most coil steel inks for construction are used outdoors, and sunlight is regarded as the standard light source in outdoor environments. For household appliance coil steel inks, due to their usage characteristics, they are mostly used indoors. Therefore, the A standard light source is adopted for color measurement of samples based on indoor lighting conditions. The A light source is a carefully specified tungsten light source. Other light sources, such as fluorescent light sources, can be used in many types of applications. For example, some textile factories use fluorescent light sources. Therefore, a reasonable light source should be selected as the mutually recognized measurement method based on actual usage conditions and user requirements. Once agreed upon by both parties, color measurement must be conducted under the same conditions. This helps reduce unnecessary systematic errors and human errors, achieving the optimal consistency in color measurement. 

The 3nh high-precision spectrophotometric colorimeter adopts a combined LED light source with long lifespan and low power consumption, which includes UV (ultraviolet) and UV-excluded options. This design can meet the color difference detection needs of different users and supports the selection of multiple light source modes.
