    Q1: How does a colorimeter work?
    A1: Colorimeters rely on the concept of the Beer-Lambert law, which assumes that the absorbance of a substance is proportional to its concentration. For example, the higher the concentration of a solution, the higher the absorbance reading. Many chemical and biological experiments are based on this concept. To obtain a Beer's law curve, several standards (solutions of known concentration) are prepared and their absorbance values are determined using a colorimeter.

    Q2: What is colorimetry?
    A2: A colorimeter is a device that measures light absorbance (how much light is absorbed) and light transmission (how much light passes through) in a liquid by analyzing the intensity of the color.

    Q3: What are the limitations of a colorimeter?
    A3: One limitation of chemical colorimeters is that differences in certain substances may lead to inaccurate test results. According to Global Water Instrumentation, because these differences are different for each substance, a chemical colorimeter alone is not a completely foolproof testing device.

    Tips: How does a pocket colorimeter measure color?

    In a pocket colorimeter, a beam of light with a specific wavelength is passed through a series of lenses that direct colored light into the measurement device. This analyzes the color compared to existing standards. The microprocessor then calculates the absorbance or percent light transmission.

    This is the best colourimeter I have ever used
    I have used many different types of colorimeters over the years, but this SISCO digital colorimeter is by far the best. The unit is very accurate and consistently provides accurate color measurements. The software is easy to use and allows me to save and organize my data quickly. The customer support team is also very helpful and responds quickly to any questions I have!
