A colorimeter is a device that measures the absorbance of particular wavelengths of light by a specific solution. This device is commonly used to determine the concentration of a known solute in a given solution. The colorimeter measures the transmittance and absorbance of light passing through a liquid sample. The “AQ3700 colorimeter” offers a wide range of tests on water, wastewater, and soil. Moreover, this equipment uses Environment protect agency (EPA) approved methods.
This equipment has 90 preprogrammed methods for common test parameters with an automatic selection of 6 wavelengths. The colorimeter is capable of performing various tests such as COD, pH, sulfate, iron, silica, nitrogen, chlorine, and many more.
- COD test- 0 to 15,000 mg/l
- Sulfate test- 2 to 200 mg/l
The colorimeter test results can be used for different engineering analysis. For example, COD test results can be used for environmental impact analysis of different organic chemicals. Sulfate test results play an important role in the selection of stabilizers for clay soil stabilizations, earth dams, slopes, and earth-retaining structures.
