Uses for Colorimeters

A colorimeter is a measuring instrument used to determine the quantity of a substance from the color it yields with specific reagents. Colorimeters are used by diamond dealers to determine the transparency of precious gems and stones. Other uses of colorimeters include measuring the accuracy, quality, and condition of electronic components and identifying the characters of pulp paper and printing ink.

  1. Laboratory Uses of Colorimeters

    • Laboratory colorimeters play a vital role in many types of scientific research and clinical settings by determining the optical density of a solution at certain wavelengths. They also measure the concentration of solid matters. Not all colorimeters are bulky; some are small enough to be used outside. These hand-held, heavy-duty colorimeters are typically used in water and environmental studies.

    Colorimeters in Food Preparation

    • Colorimeters are used domestically in food preparation. They provide the user with color indexes, which narrow down the choices during application, cutting costs and saving time. The advantage of using color indexes is that they offer precise information regarding the process rather than a multitude of data to screen out. In addition, colorimeters eliminate the possibility of subjective judgments by providing hard data. The advanced CR-410FF colorimeter can precisely calculate the color of cooked French fries. Until the introduction of colorimeters in the food industry, the color of cooked French fries was measured visually.

    Colorimeters in Dental Applications

    • Resin, which has recuperative effects on teeth, is used to plug drilled teeth. The outer surface of resin, though, is liable to be stained by the effects of tobacco and/or foods, lowering its aesthetic value. This problem must be resolved before resin can be used as a restorative material for dental treatment. Studies indicate that surface treatment agents offer good protective coverage for pigmentary deposits of food that stain resinous substance. The research includes colorimeter devices that precisely calculate and interpret the color of the sample (i.e., resin). A sample is treated by a surface treatment agent and then immersed into a tobacco solution. The color differences between treated and untreated samples are measured by colorimeters.

    Colorimeters for Monitor Calibration

    • Sometimes, computer monitors require fine-tuning for neutral color as well as white-and-black set points. The degree of accuracy can be improved if a colorimeter is used during calibration. Colorimeters precisely measure screen colors. This arrangement replaces visual standards and therefore takes the subjectivity out of the process. Human eyes cannot detect small color changes because our color sensitivity is limited.
