The analyzer has two separated enclosures with two lockable doors. The top enclosure, called the electrical enclosure, includes the main power supply, the controller PCB assembly and the touchscreen interface. The bottom enclosure, called the liquids enclosure, includes all the components involved in the sample a​nd reagent flow, mixing and reaction stages (sampling pump, reagent micro pumps and colorimetric reaction cell). Numerous analysis configurations can be programmed, depending on the accessories and the number of micro-pumps mounted in the liquid enclosure. The CA600 analyzer typically makes a single measurement per analysis cycle, although a user defined calibration or cleaning sequence can be added to proceed the measurement every "X" number of measurement cycles. A standard sequence would consist of a drain and rinse cycle, sample acquisition, addition of reagents, mixing time, waiting period and measurement. Higher range samples are accommodated​ using the optional dilution module.

The colorimetric analysis is based on the measurement of color formation in the sample after the addition of reagents. The absorbance​ of the solution is measured through a quartz reaction cell at a specific wavelength using a long life LED light source and a photometer. The absorbance is related to the sample concentration according to the Beer-Lambert Law.

The CA600 makes two measurements during an analysis cycle. The first measurement is of the raw sample which sets a baseline for the compensation of color, turbidity and optical characteristics of the cell. The second measurement occurs after the color forming reagents have been added to the sample, mixed and adequate time has passed to allow for color formation. The concentration is calculated using the difference between the two absorbance measurements and the stored calibration information in the analyzer. Some measurements can be achieved with significant sample conditioning by using Ion Selective Electrodes (ISE). The CA600 can achieve the same measurement with less process alteration and less reagent used. The CA600 analyzer home screen displays the measured parameter, the status, % reagent volumes, time and menu choices. The on screen HELP menu includes information on start up, shut down, start/stop commands, calibration, function list, programming, maintenance and troubleshooting. Outputs include two alarm relays and 4-20 mA channel.
