Inc. manufactures colorimeters for water testing and analysis. Colorimeters are used to measure the concentration of various chemicals and analytes .
Colorimetric analysis is a recognized method for reliable testing of water samples.
The following is an overview to explain how and why Colorimetric methods are so excepted around the world and why these methods work so well. A colorimeter is an instrument for measuring color differences by means of comparison with a standard. Hydrodyne colorimeters have a built-in standard curve which is saved on a computer chip for repeated use. A sample of unknown concentration is measured for light transmission or absorption and compared to these standard results over the operating range of the test. The microprocessor controlled instrument then compares the sample to the standard curve.
