Kemtrak is an industry leader in the development of photometers for any and all industrial applications.
The Kemtrak DCP007 is an industrial UV-VIS-NIR photometer designed to accurately measure the color and/or concentration of liquids. Real-time measurement results are in absorbance and can be displayed in standard units such as PCU (Pt-Co), Hazen, APHA, Saybolt, %wt and many others. The DCP007 uses a high-performance, long-life LED light source with robust industrial fiber optics to provide a measurement with very high precision. A proprietary dual-wavelength four-channel measurement technology allows accurate measurement of both highly colored and trace-color levels. Three variants are available, - UV, VIS and NIR. UV is used for concentration, VIS of color and NIR of water and trace water in solvents. Each analyzer has a primary absorbing wavelength to accurately measure the substance or color of interest. A second wavelength is used to compensate for solution turbidity and optical window fouling.
Since optical fibers are used to transmit the light energy to the measurement point and back, the measurement cell contains no electronics, moving parts or sources of heat. Standard measurement cells are manufactured in robust stainless steel and use sapphire windows to provide long and maintenance-free operation. Measurement drift caused by LED light source or filter aging is negligible, and once set, instrument recalibration is not required.
Where calibration is required, the Kemtrak DCP007 employs a simple automated QuickCal one-point and zero-calibration method suitable for the vast majority of applications.
What is a Photometer?
In-line photometers use light to provide real-time measurement of the color or concentration of components in a liquid (or gas) process stream. Photometers can be configured for a variety of purposes, with the configuration and technique used depending upon the specific measurements needed. Simply put, an industrial photometer is used to measure light after it has passed through an industrial process stream.

What are the most common types of photometers?
All photometer designs are based upon a single operating principle: shining a beam of light into a sample of liquid or gas, and then measuring the changes in that light after it has passed through sample to calculate one or more variables.
Differences in materials and applications requires the use of different wavelengths of light and measurement techniques. Today, there are many types of photometers found in commercial and industrial applications, with the following being the most common.
The Kemtrak TC007 turbidimeter utilizes principles of light scattering to measure the presence of suspended solids.
The Kemtrak TC007 is an easy to operate industrial process fiber optic turbidimeter designed to accurately measure the concentration of light-scattering components. Measurements are real-time and in-line. Long-life solid-state LED lamps and precision fiber optics are used to provide drift and noise free measurement at very high precision.
The Kemtrak TC007 can be configured to use the nephelometric method of turbidity measurement in accordance with International Standard ISO7027:1999(E). In this mode, a proprietary algorithm mathematically combines the ratio of attenuated and scattered light to accurately monitor the turbidity of the sample. Automatic compensation of sample color and fouling of the optical windows ensures trouble-free operation.
Maintenance-free measurement cells with scratch-resistant sapphire windows have no electronics or moving parts, making the unit suitable for use in hazardous areas.

What is a turbidimeter?
Turbidimeters are scattered light instruments which analyze the relative clarity of a fluid by measuring the light scattered by particulate matter in a fluid stream. The incident light must be made parallel (collimated), and the detector set to the side of this incident beam to capture light as it strikes particles and is diverted from its original trajectory. This technique is limited to lower levels of turbidity in a stream. Once that limit is reached, absorbance techniques can be used. Correspondingly, once the absorbance unit reaches its maximum detection level, backscattered light can be used.
Each technique has a relative sensitivity, and while there is a great deal of overlap between the techniques, it is important to select the right one for the application to get the best and most satisfactory results.
