Water engineers responsible for municipal or industrial water and wastewater will find the new versatile single or dual parameter CA-6 UV Family of Spectroscopic Analyzers from Electro-Chemical Devices can monitor any two selected parameters in separate measurement ranges for ammonia, nitrate or chemical oxygen demand.
ECD’s CA-6 UV Analyzer Family provides a highly accurate, reliable and economical on-line sampling system that’s designed with UV absorption sensor technology to monitor harmful pollutant parameter levels. The CA-6 Analyzer’s sensors are available in multiple parameter measurement ranges.
Each model is easy to order with either a single parameter or dual parameters in the factory pre-calibrated measurement ranges. Everything needed comes in one box ready to install and start-up. A single technician can complete the installation process in 15 minutes by connecting the sample, waste and cleaning solution (reagent) lines and powering up the analyzer. Accessing the chosen factory pre-calibrated parameter data or customizing an analysis routine is easily done with user-friendly intuitive menus and a touch screen display.
Each parameter is analyzed based on the measurement of UV absorption in the sample. The absorbance of the solution or gas is measured through a quartz flow cell at a specific wavelength using a long-life Xenon lamp and photo detectors. The absorbance level is directly related to the sample concentration according to Beer-Lambert’s Law, which correlates the attenuation of light to the properties of the material through which the light is traveling.
Accuracy is 5% for the measurement of Ammonia, Nitrate and COD with the CA-6 UV Analyzer based on a sample temperature range of 0 to 80°C, but the sample must be liquid and not frozen. Repeatability varies based on the parameter chosen and the single or dual parameter configuration, ranging from 0.15 to 3 percent.
The versatile CA-6 Analyzer is designed with four alarm relays. A single 4-20 mA analog output is included with 12-bit resolution. RS232 communications are provided for data download to a CSV file, with an optional RS485 MODBUS communication module available.
