Color, Concentration, Turbidity



The Kemtrak 007 series are state of the art industrial optical analyzers designed to accurately measure and report specific properties of liquids (and gases) inline and in real time. Based upon, absorbance, light scatter and fluorescence, Kemtrak instruments are used widely in industry to measure color, concentration, turbidity and solids concentration in many different applications.

Each unit consists of a state-of-the-art analyzer using high performance LED technology, rugged industrialized fiber optic cables and an inline flow cell or probe with sapphire windows. The key to the outstanding performance of Kemtrak analyzers is that the output of the LED’s is kept extremely stable over long periods of time, essentially eliminating the drift seen on so many older design optical instruments. High reliability ensures that maintenance requirements are very low – cost of ownership is one of the most attractive amongst inline optical instruments in the marketplace today – and while each instrument is carefully configured to suit each and every application, change to repurpose the instrument in the field is a quick and simple task.


Kemtrak turbidimeters provide reliable online turbidity measurement for a whole range of applications throughout industry. With options to use either 90° side scatter, 180° attenuation or back scatter techniques, Kemtrak turbidity analyzers can measure from 0.01 NTU to 10000 NTU or more.

Inline flow cells are available from ½” to 4” with a variety of different process connections, pressure/temperature ratings and a variety of different wetted materials.

Color and Concentration

The Kemtrak DCP007 is an easy to operate industrial fiber optic photometer designed to accurately measure the concentration and color of process samples. Measurements are real time and in-line.

A proprietary dual wavelength four channel measurement technique and advanced digital electronics design allows deep absorbance measurement to 5 AU. Automatic compensation for sample turbidity and/or fouling of the optical windows ensures trouble free operation.

Maintenance free measurement cells with sapphire windows have no electronics or moving parts making them suitable for hazardous area use.

NIR Analyzers

The Kemtrak DCP007-NIR analyzer is an advanced dual wavelength NIR photometer designed to accurately measure the concentration of process liquids and gases with near-infrared (NIR) absorbance between 800 and 2000 nm.

Examples of NIR measurements include moisture (water & trace water), ethanol, methanol, sodium hydroxide, ammonia and continuous fuel identification.

Suspended Solids

The Kemtrak NBP007 is a high resolution backscatter photometer that revolutionizes the measurement of high concentration suspended solids.

Traditional turbidity based optical measurement instruments lack resolution and stop working at approximately 1% suspended solids due to the extremely high optical density. This limitation is overcome with the NBP007 and for the first time the operator can monitor and have complete control over their process at any concentration.

UV Absorbance

UV Absorbance for Sugar Color

The Kemtrak DCP007-UV process analyzer uses ultra-low power cold light LED’s at only the wavelength required for the analysis, exposing the sample to thousands of times less energy than traditional UV photometers. Traditional UV photometers use mercury vapor lamps that continuously expose the process stream to high intensity broad spectrum UV radiation and heat generated by the lamp.

Convenient zero dead-volume hygienic measurement cells contain no electronics or moving parts and are well suited for hazardous environments. NIST traceable validation filters are available to verify analyzer performance without process interruption.

Fluorescence (Oil-in-Water)

A Kemtrak FL007 fluorometer is used to accurately monitor fluorescent substances. An advantage of this technique is extremely low concentrations can be detected – parts per billion can be achieved.

The Kemtrak FL007 analyzer uniquely utilizes both fluorescence and turbidity measurement using proprietary dual wavelength ratio measurement techniques for continuous monitoring in applications like trace oil and hydrocarbon contamination in water. The FL007 can be configured to monitor other fluorescing substances (such as Fluorescein) in line in real time for leak and marker detection.
