    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.

Calibrating a colorimeter before testing is critical for accurate, reliable color data—counteracting instrument drift, environmental interference, and component wear to ensure measurements reflect true sample colors. It guarantees compliance with industry standards, eliminates costly rework from flawed data, maintains brand consistency across batches/locations, and ensures data comparability with clients or regulators.

Calibrating a colorimeter before use is primarily to ensure the accuracy of measurement data and compensate for errors caused by the aging of internal components (such as light sources and phototubes) or environmental changes.

Below are the specific reasons: 

  1. Compensation for Component Aging and Environmental Influences

  2. Compensation for Environmental Factors

  3. Standardization of Measurement Baselines

  4. Operational Specification Requirements

3nh colorimeters are designed for immediate measurement upon startup. However, calibration (via black-white correction) is mandatory for the first use, sudden environmental changes, or abnormal data to restore measurement accuracy.

3nh high-precision spectrophotometers are the best choice for accurate color matching.

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.
