Colorimeters
There are two types of color measuring instruments: colorimeter and spectrophotometer. 3Color® produces 2 models of colorimeters that have a modern design, user-friendly navigation and a competitive price. Both of our models are portable battery-powered devices.
The colorimeter is widely used in various industries, such as plastics, printing, paints, textiles, food, etc. It measures basic color values such as L*a*b *, L*c*h*, color difference ΔE and ΔLab in accordance with CIE color space.
The colorimeter can be used to determine the color and color differences. You can use it for simple color quality control or to find a color card (RAL, Pantone, NCS). To make the choice of the instrument more specific and to meet the expectations of our customers, we created 3 options depending on the application in the CP-200 model (glass protective lens, real-time camera, color card reader function)
A kit is available to measure the insoluble color bodies generated by grease in operating turbine oils using membrane filter colorimetry (MPC).
What should be the price of a colorimeter?
The price of a colorimeter mainly depends on its measurement accuracy and the functions it offers. Low-cost colorimeters in the 200–1000 EUR range have low-quality detectors, often based on trichromatic converters. The consequence is low measurement repeatability and essentially no compatibility with NIM color standards. The price of a mid- or high-class colorimeter is usually around 1500–2000 EUR.
What is a colorimeter?
A colorimeter is a device for measuring color. Historically, before the spectrophotometer appeared, the colorimeter was the only tool for color analysis. Currently, the name colorimeter is reserved for cheaper devices equipped with a trichromatic detector or one that estimates the spectral curve.
What is the difference between a spectrophotometer and a colorimeter?
The most important difference is measurement accuracy and the type of detector used. Colorimeters use cheaper methods of color analysis, e.g., trichromatic analysis or spectrum estimation. A spectrophotometer has a spectral detector with spectrum analysis up to 10 nm.
Colorimeter for cosmetology and cosmetics.
A colorimeter in cosmetology can have many applications. It is mainly used for measuring the color of cosmetic products – where constant control of color quality is required. It can also be used to assess skin color as part of the ITA˚ test.
What is the application of a colorimeter?
A colorimeter is used in many branches of industry and science. It is most often used as a basic tool for evaluating color where the device’s price is of significant importance. However, colorimeters are increasingly being replaced by spectrophotometers in color evaluation.
Colorimeter – operating principle.
A colorimeter, like any device for color measurement, analyzes light reflected from or transmitted through a sample. Light analysis makes it possible to convert raw data into a language understandable to humans, for example by converting data into one of the colorimetric spaces.
Construction of a colorimeter.
A colorimeter consists of several important elements such as: a detector, a light source, a measurement chamber or aperture, and a data display. In colorimeters with d/8˚ geometry, miniature Ulbricht spheres are used to scatter light.
Colorimeter for printing.
A colorimeter in printing is most often used for quality control of finished products. The most common measurement is the deviation from the reference color using ΔE.
What is a colorimeter used for?
A colorimeter is most often used to assess the color differences between a reference and a test sample. It can also be used to determine colorimetric coordinates, for example in the CIELab space, and to calculate colorimetric indices.
Color measurement with a colorimeter.
Color measurement, or colorimetric measurement, involves analyzing the color of light reflected from or transmitted through a sample. Visible light carries information about color. Color measurement is performed by converting this information into a digital (quantitative) expression of color.
What is a colorimetric measurement?
It is a measurement aimed at expressing color in digital form. Color coordinates and its properties – e.g., gloss level – are analyzed. A colorimetric measurement most often concerns comparing a sample to a reference.
What is colorimetry?
Colorimetry is the science concerned with the measurement and description of phenomena related to color perception. It focuses on knowledge from physics and standards related to color analysis. It also often includes practical, non-formalized knowledge, e.g., directly derived from industrial measurement methodologies.
