How it works
The Kemtrak DCP007 color & concentration analyzer consists of three components:

Control Unit. The control unit contains all electronics including light source and detectors.
Measurement Cell. Robust in-line (flow through) industrial process connection.
Fibre Optics. Industrial grade fibre optic assembly connects the control unit to the flow-cell.
The configuration shown here is a 316L stainless steel DIN DN50 flange measurement cell with stainless steel fully interlocked fibre optic assembly. Both measurement cell and fibres can withstand 250°C (482°F)

Measuring principle
The Kemtrak DCP007-NIR photometer measures at two wavelengths. A primary “absorbing” wavelength is used to measure the concentration of the chemical being monitored while a “non absorbing” reference wavelength is used to compensate for turbidity, air bubbles and/or fouling.Kemtrak industrial UV-VIS-NIR process photometer dual wavelength detection

The Kemtrak DCP007-NIR photometer uses precision fiber optics to shine a precisely focused monochromatic light through the process medium and back to a photo-detector.

The attenuation of the transmitted light beam caused by NIR absorbing substances in the process medium is mathematically described by the Beer-Lambert law.

Applying the Beer-Lambert law (below), the concentration of the sample can be calculated.

A = ε l c

where:

A = absorbance (= – log transmittance)
ε = molar absorptivity coefficient
l = optical path length
c = concentration of absorbing species

The Kemtrak DCP007 photometer is ideally suited for industrial environments where simplicity, stability and low maintenance is vital.
