A colorimeter is a scientific instrument used to measure and analyze the color characteristics of objects or materials. It quantifies color by evaluating specific parameters related to human visual perception and standardized color spaces.

The Ideal Accurate and User - Friendly Spectrophotometer for Your Needs 

This Spectrophotometer device measures the reflectivity，absorbance, transmittance, and fluorescence of light passing through samples, providing invaluable data for a wide range of applications, provide unrivaled accuracy for reliable results. 

Selecting an appropriate spectrophotometer offers significant advantages for precision color analysis and quality control. When choosing an accurate and user - friendly spectrophotometer, consider factors such as wavelength range, sensitivity, sample handling options, and available software features. By investing in the right spectrophotometer, you can streamline your analytical processes, obtain more accurate results, and enhance the overall efficiency of your laboratory or industrial operations. 

 Choosing the right model—whether portable, benchtop, or inline—aligns technology with specific industry needs, ensuring long-term reliability and optimized color management.

Depending on model and location, delivery time is usually 2-4 weeks for standard models and 4-6 weeks for built- to-order ones. 

The machine used to measure color is primarily called a colorimeter or spectrophotometer. 

Spectrophotometer: The most common and precise type. It analyzes light reflected/transmitted by an object across the visible spectrum to quantify color accurately. A spectrophotometer can measure colors on smooth or matte surfaces, as well as textured, glossy, mirror-like surfaces, and special effect colors. It measures the reflected light of a sample at a fixed angle (e.g., 45˚) or captures light reflected at all angles to calculate color measurements that closely match what the human eye perceives. Additionally, similar to how humans flip a sample to view colors from different angles, a spectrophotometer is suitable for measuring a variety of materials and surface characteristics. Widely used in industries like paint, textiles, plastics, Chemicals, Pharmaceuticals, and printing. 

Colorimeter: Also called photoelectric integrating colorimeter, a simpler, more cost-effective option. It measures color based on three primary colors (RGB) and is suitable for basic color matching needs. A photoelectric integrating colorimeter is a color measurement device based on the photoelectric integration principle. It directly measures the tristimulus values XYZ of an object's color using three color filters (red, green, blue) and silicon photocells as three sensors. The color measurement principle of this instrument imitates the human eye's mechanism of perceiving the three primary colors (red, green, blue). It corrects the relative spectral sensitivity of the detector through color filters to match the CIE-recommended spectral tristimulus value functions x(λ), y(λ), and z(λ).

Spectrocolorimeter: Combines the functions of spectrophotometers and colorimeters, offering both spectral data and color space values for comprehensive analysis.

Gloss level is not given out in percentage but in gloss units (GU). In practice, however, 100 GU is considered 100 percent reflective. To contrast visually, the 20-40 GU is a low-gloss surface, and 85 or more is almost 100 percent mirror-like reflection.

To extend the life of a haze meter, keep the instrument dust-free and clean, regularly calibrate it, and control for a stable dry storage. For better results, avoid letting the optics dry, and leave the meters under sunlight. For optimal performance, have the meter professionally serviced once a year.

Gloss is the general reflectivity of a surface, which encompasses a variety of degrees. One particular type of finish is high gloss, which has the maximum shine and reflectance. It increases the richness but emphasizes flaws as compared to satin or matte.

The most common standard measuring gloss is ASTM D523, which covers the procedures of using a gloss meter at 20°, 60°, and 85° angles. The other international standard that is widely used in industrial and laboratory applications is the ISO 2813.

Usually you will find haze and transmittance standards of ASTM D1003, ISO 13468, & JIS K7105.

An inappropriate viewing angle may lead to reflections or color shifts in the light. The correct angle of 45 or 0 will provide the real color of the assessment without the distraction of glare.
