DCP007 Industrial Photometer
The Kemtrak DCP007 is an industrial UV-VIS-NIR fiber optic photometer designed to accurately measure the concentration of light absorbing substances.
The Kemtrak DCP007 uses a combination of long life, solid state LED lamps with fiber optics that provide a measurement with very high precision. Thanks to a proprietary dual wavelength four channel measurement technique and advanced digital electronics design, high concentration to ppm trace analysis is no problem. The primary “absorbing” wavelength measures any changes in the process medium, while the second reference wavelength, which is not absorbed by the process medium, compensates for turbidity and/or fouling of the optical windows.
Since optic fibers are used to pipe light to the measurement point and back, the measurement cell contains no electronics, moving parts or sources of heat that result in condensation on the optical surfaces. Standard measurement cells are machined in sanitary grade stainless steel with sapphire glass.
Measurement flanges- DIN Flange DN25, ISO DN25 TriClamp & ISO DN50 TriClamp.

The Kemtrak DCP007 color & concentration analyzer consists of three components:
- Control Unit. The control unit contains all electronics including light source and detectors.
- Flow Cell. In-line (flow through) measurement cell.
- Fibre Optics. Industrial grade fibre optic assembly connects the control unit to the flow-cell.
The configuration shown here is a 316 stainless steel DN25 DIN Flange flow cell with stainless steel fully interlocked fibre optic assembly. Both flowcell and fibres can withstand 200°
|
|
|
The Kemtrak DCP007 photometer measures at two wavelengths. A primary "absorbing" wavelength is used to measure the substance being monitored while a "non absorbing" reference wavelength is used to compensate for turbidity, air bubbles and/or fouling.
Fiber optics are used to shine a precisely focused light beam through the process medium and back to a silicon photo-detector. A second photo-detector is used directly on the lamps to compensate for temperature effects and aging. The resulting measurements are very accurate with low drift and long-term calibration stability.
The attenuation of the transmitted light beam caused by light absorbing substances in the process medium is mathematically described by the Beer-Lambert law.

DCP007NIR Industrial Photometer
The Kemtrak DCP007NIR is an advanced dual wavelength photometer designed to accurately measure the concentration of liquids and gasses with near-infrared (NIR) absorbance from 1000 to 2000 nm.
Examples of NIR measurements include water, ethanol, sodium hydroxide, ethylene glycol, acetic acid and continuous fuel identification.
Optic fibers are utilized to pipe the light from within the DCP007NIR enclosure to the sampling point and back. This is a major benefit as all the electricity is kept within the analyzer enclosure permitting safe operation in even the most hazardous of environments. An additional benefit is that the light source is "cold" and does not affect the sample.
DIN Flange (DN25 & DN50) sensor flanges with 10mm optical path length
Optic fibres can be ordered in lengths up to 50m and are well suited for harsh industrial environments. Our standard fibers have a silicone-coated steel jacketing and can withstand temperatures up to 200 °C. A range of flow-cell manifolds are also available dependent upon the process and application.

The Kemtrak DCP007NIR uses fiber optics to shine a precisely focused monochromatic (single wavelength) light beam through the process medium and back to a silicon photo-detector.
The attenuation of the transmitted light beam caused by light absorbing substances in the process medium is mathematically described by the Beer-Lambert law.

TC007 Industrial Turbidimeter
The Kemtrak TC007 is a robust in-line fiber optic
turbidimeter designed to accurately measure the
concentration of light scattering components for a wide range of industrial process applications.
The Kemtrak TC007 measures attenuated light and/
or scattered light which is mathematically combined
using a ratio algorithm to accurately monitor the
turbidity of the sample. The Kemtrak TC007 can be configured to use the nephelometric method of turbidity measurement in accordance with International Standard ISO7027:1999(E).
Optic fibers are used to pipe the light from within the TC007 enclosure to the sampling point and back. This is a major benefit as all the electricity is kept within the analyzer enclosure permitting safe operation in even the most hazardous of environments.
The Kemtrak TC007 has an easy to use menu based software with a user configurable display that shows the turbidity value in real time. Additionally, the TC007 has a database and event handler to capture vital process information for use in quality assurance and plant control reports. All data is easily transferable to a PC via a USB interface.
