Colorimeters are used to determine the color of different types of object compared to pure white. I used the colorimeter to measure the fabric colors after they have been washed and stained. I compared it to my control sheet, which was to represent pure white. Colorimeters have a strong light inside the machine. The light bounces off the object and the amount of light that is sent back towards the sensor is measured and is the measurement for the whiteness of that particular cloth.
Colorimeters read in numerical values.
Detergents are made up of a lot of materials and have different names. I know how detergents work and how and where they are made. I used a colorimeter to conduct part of my experiment and I can explain about it. The original purpose of this experiment was to determine which brand of detergent worked most effectively on certain types of fabric stains. Overall, Arm and Hammer was the best on average.
