A colorimeter is a tool used to determine the concentration of a chemical in a sample. It is a portable and compact device that can be used both in the laboratory and in the field. Therefore, at Kalstein we have the optimal colorimeter that measures the absorbance of a solution, and converts the concentration of a substance into a numerical value. This tool is very useful for measuring the concentration of nutrients in water, as accurate and fast results can be obtained.

Its operation is based on the principle of light absorption. Light is composed of different wavelengths, and each chemical substance absorbs light of a specific wavelength. The color of a substance is the result of the wavelength of light that has not been absorbed by the substance. For this reason, some substances appear as if they have a color, while others do not.

Colorimeter Measurement Scales

The absorbance of a substance is measured using an absorbance (Abs) scale on the colorimeter. This scale ranges from 0 to 1, and represents the percentage of light that has been absorbed by the substance. For example, a substance with an absorbance of 0.5 would absorb 50% of the incident light. The concentration of a substance can be calculated using the following formula: Concentration (C) = Absorbance/Absorption Coefficient (A) where A is the absorption coefficient of the substance. A drop of the sample should be applied to the quarter bead or filter, and then the quarter bead or filter should be placed in the colorimeter. The colorimeter will emit an audible and/or visual signal to indicate the absorbance of the sample.

Next, the absorbance measurement should be taken and the concentration of the substance calculated using the above formula. Finally, it is a very useful tool for determining the concentration of nutrients in water, as it providesaccurate and fast results.

Determination of Waters with the use of Colorimeter

The colorimeter is used to compare the water sample with a reference solution of known color. A chemical reaction occurs between the water and the reference solution, and the colorimeter measures the color intensity of the reaction. From this measurement, the amount of chlorine present in the water can be determined. High levels of chlorine indicate increased contamination of the water, and must be treated before the water can be used .

They can also be used to determine other contaminants in water, such as sulfate which is commonly found in water, and can cause health problems if ingested in large quantities. It can damage equipment if found in the water to be used. Therefore, it is important to determine the sulfate levels in the water before use. The colorimeter is also used to measure the pH of water and the measure of the acidity or alkalinity of a substance is measured on a scale of 0 to 14, with 0 being the most acidic and 14 being the most basic. Water must have a pH between 6.5 and 8.5 to be safe for human consumption.
