The COLORsmart-AD model process photometer measures the color of liquids in the process.
Suspended solids (turbidity) absorb light in the same way as color. The difference is that color absorbs only specific regions of the visible spectrum, where suspended solids absorb light across the entire spectrum. Therefore, color measurement is performed at two different wavelengths. The measurement channel detects the absorbance caused by both color and suspended solids, while the reference channel primarily measures the absorbance caused by suspended solids. By calculating the difference between the two measurement signals, the actual color concentration can be accurately determined.
The COLORsmart-AD model enables reliable inline color measurement of liquids directly within the process. By simultaneously measuring at two different wavelengths, the system delivers highly accurate results while compensating for the effects of turbidity, window contamination, and lamp aging.
The sensor is equipped with long-life LEDs for low-maintenance operation and extended service life. The measuring cell is manufactured from POM as standard but is also available in stainless steel 1.4404 or other materials to suit specific process requirements. Additional material options are available on request, allowing the system to be individually adapted to a wide range of applications.
Color is a sensory perception generated by light and processed by the human eye. In physics, light is described as an electromagnetic wave. The visible range of these waves lies approximately between 380 nm and 750 nm.
When light strikes the eye, it gives rise to a sensation of color. However, this perception is not an objectively measurable quantity—like temperature or pressure—but rather a subjective impression formed in the brain.
White light contains all the colors of the visible spectrum. A color arises when specific wavelengths from this light are absorbed, while others are reflected or transmitted. The remaining wavelengths then determine the color impression we perceive.

The Model C1 measurement amplifier can be used with most optical sensors. System programming and calibration are performed via a PC or laptop using menu-driven software. Calibration can be carried out using one or more samples. All settings and calibration values can be backed up externally on your PC’s hard drive.
The Messenger Signal Amplifier is compatible with all optical sensors from the Chemtronic and Monitek product ranges. It allows up to four single-channel sensors to operate simultaneously, while also supporting the independent operation of different sensor types. Individual measurement signals can be freely linked, making the system ideal for applications such as automated dosing control.
Configuration is carried out via a PC or laptop using intuitive menu-guided software. As an option, the Messenger is available with an integrated Panel PC, providing a complete standalone solution for industrial process monitoring and control.
