Why is the three angles color spectrophotoemter suitable for automobile paint ……

As for the color matching scheme of automobile paint, there are various colors in automobile paint. In order to improve the color matching speed, “triangle color difference meter + computer color matching system” has several characteristics compared with manual color matching: 1. It makes color matching job much easier. 2. It can gives different options. 3. Fast test twice can get formula. 4. Simple instrument interface which is easier to use. 5. Rubber pat to prevent the instrument from sliding when reading 6. Small aperture which is convenient to measure on curve surface 7. Bluetooth function can be custom made […]

Top ten brands of colorimeter in China

Some people like red clothes, while others like yellow clothes. When people choose goods, they often choose different goods according to the color difference. In order to better control the color difference of goods, it is necessary to use professional equipment: colorimeter. Today, I’d like to introduce the top ten brands of colorimeter in China. Development history of colorimeter in China To understand the colorimeter in China, we must first talk about the development history of colorimeter. Color management has been a scientific subject since ancient times. At that time, the ancients described the cognition of social reality through various […]

Colorimeter Vs Spectrophotometer

What is Colorimeter? A colorimeter is a tristimulus color measurement tool that provides an objective evaluation of color characteristics based on light passing through the primary filters of red, green, and blue. It simulates how the human eye perceives color. How it works? Using an internal light source, a colorimeter shines light down onto the surface of the sample. As the light reflects back up to the device, it passes through three filters: red, green and blue. These filters distill tri-stimulus (RGB) values that match how our eyes see color. Colorimeter applications: Colorimeters can be used to test the surface color of objects. They’re […]

How to calculate haze with haze meter TH-100?

Haze : Wide Angle Scattering The light before passing through the sample is called incident light, the entire light after passing through the sample is called transmitted light, and the scattered light with a scattering angle greater than 2.5 ° after the transmission sample is called scattered light, haze Is the scattered light than the transmitted light (as show in green color of picture 2) and Tt is the total transmitted light (as show in pink color of picture 1). So haze equation is Haze = Td / Tt. Haze Measuring Instrument We will introduce how to measure haze by Haze Meter TH-100. It can meet both […]

How to measure gloss with gloss meter?

What is gloss? Gloss is the surface characteristics of an object, which depends on the specular reflection ability of the surface of the object to light. Specular reflection refers to the reflection phenomenon where the angle of reflection is equal to the angle of incidence. The greater the value of Gloss, the higher the degree of mirroring on the surface of the object. There are three common Gloss measurement angles: 20°, 60°, and 85°. The larger the measurement angle, that is, the larger the incident angle of light, the more obvious the change is in the high Gloss area, so the […]

Upgrade of Haze Meter

Haze meter is suitable for the color, haze, spectral transmittance and all-transmittance measurement of transparent and translucent materials such as plastic, film, glass, LCD panel and touch screen. It is a very essential instrument for samples’ haze, transmittance color and clarity quality control. For better user experience, we have updated our instruments. The following is the detail information. Upgrade of Haze Meter 1. Haze meter CS-700 has added color functions on the basis of the original, and now has a comprehensive color measurement function, which can measure dozens of color parameters such as Lab, yellowness index, whiteness index, Gardner,Pt-Co, etc. CS-700 Color and Haze […]

Portable color spectrophotometers measure both opacity and strength

Portable color spectrophotometers made by CHNSpec Tech can measure both opacity and strength on instrument. We will introduce these two parameter now. Part 1. Opacity Introduction Opacity is a measure for hiding power: Opacity% = Y (black background) / Y (white background) * 100% The measurement of opacity is generally used in plastic products, spray coating, glass, transparent or translucent products and other industries. Part 2. Color Strength, Apparent Strength and Integrated Strength Introduction Color Strength SWL This strength is also known as the chromatic color strength. It describes the ratio based on the (K/S-value) of the Sample in relation to […]

Why do Haze Meter Meet ASTM D1003 and ISO 13468/14782 Standard?

What is ASTM D1003 requirement on haze meter structure? The following picture is the ASTM D1003 requirement on haze meter structure: ASTM Requirement on Haze Meter 1). The opening area in the integrating sphere does not exceed 4% of the total internal surface area of the integrating sphere; 2). The center of the light entrance and the light exit is on the largest circumferential section of the integrating sphere, and the angle with the center of the sphere is not less than 170°; 3). The opening angle formed by connecting the center of the light entrance to the light exit […]
