    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.

FAQs About NR145 Colorimeter

Because color perception depends on the following factors: 

Light source - For example, incandescent lamps emit orange light, while fluorescent lamps emit cool white light. Therefore, placing an object near different light sources will result in different perceived colors. 

Observed object - Different types of objects affect color perception differently. Examples include opaque objects, translucent objects, and transparent objects. 

Observer's position - Each observer will describe colors differently based on the position of their eyes. 

Different backgrounds - An object's color will appear duller against a light-colored background than against a dark-colored background. Different directions of light reflection from the object - Light reflected from different directions creates different color perceptions. This is particularly noticeable with metallic objects.

Different directions of light reflection from the object - Light reflected from different directions creates different color perceptions. This is particularly noticeable with metallic objects.

By addressing color-related quality control challenges, 3NH colorimeters help industries maintain brand consistency, meet regulatory standards, and enhance customer satisfaction.


A visual colorimeter is a type of colorimeter that uses the human eye to compare the color depth of a sample with that of a standard solution for semi-quantitative or quantitative analysis of substances. This method is commonly used for quick, rough evaluations in industries such as petroleum, transparent liquids, varnishes, chemicals and printing, as well as for visual color grading in quality control. Its working principle is to compare the sample with a standard and provide visual color measurement results, rather than relying on electronic sensors.

Visual Colorimeters vs. Photoelectric Colorimeters

Visual colorimeters rely on human eye observation, whereas photoelectric colorimeters use sensors to deliver higher precision, complete the measurement automatically through electronic circuits, less subjective color measurement and faster results. They are generally more suitable for rapid, on-line or portable color difference measurement.

Working principle of a photoelectric colorimeter

A light source emits light at specific wavelengths, which interacts with the object surface through reflection and transmission. The light is reflected or absorbed by the sample, and the reflected light or remaining transmitted light is received by a photoelectric sensor (photocell or photodiode). The instrument converts the light intensity signal into an electrical signal, thereby measuring the LAB color values of the sample.
