PRINCIPLE OF OPERATION

Photometry is fundamentally the measurement of the intensity of light. Observable on many levels, changes in light intensity occur as a result of interactions with different materials. Further, the Beer-Lambert Law describes a useful relationship between light and matter. Matter absorbs light in measurable amounts at specific wavelengths. The degree of absorption correlates to the concentration of matter that is exposed to the light across a known optical distance, or pathlength. Thus, chemical concentrations and physical characteristics of a process stream sample can be accurately analyzed. Effective analyzer design permits this principle to be taken online powerfully exploiting the science and achieving a high level of process control. 

Each successful ClearView db application is defined by the calibration. The calibration consists of absorption data corresponding to analytical values that describe the state of the process stream. Wavelengths specified for the application are represented by filters installed in the photometer. If and when changes occur in the process, the ClearView db measurements reflect this instantaneously.
