Electro-Chemical Devices CA-6 UV spectroscopic analysers
Water engineers responsible for municipal or industrial water and wastewater will find the single- or dual-parameter CA-6 UV family of spectroscopic analysers from Electro-Chemical Devices (ECD) can monitor any two selected parameters in separate measurement ranges for ammonia, nitrate or chemical oxygen demand (COD 254 nm).
The UV analyser family is an online sampling system that’s designed with UV absorption sensor technology to monitor harmful pollutant parameter levels. The analyser’s sensors are available in multiple parameter measurement ranges: ammonia from 0–10 mg/L or 0–1000 mg/L; nitrate from 0–30 mg/L, 0–100 mg/L or 0–250 mg/L; and COD 254 nm from 0–200 mg/L or 0–20,000 mg/L. Accuracy is 5% for the measurement of ammonia, nitrate and COD with the analyser based on a sample temperature range of 0 to 80°C, so long as the sample is liquid and not frozen.
Each model is easy to order with either a single parameter or dual parameters in the factory-precalibrated measurement ranges. Everything needed comes in one box ready to install and start up. A single technician can complete the installation process in 15 min by connecting the sample, waste and cleaning solution (reagent) lines and powering up the analyser. Accessing the chosen precalibrated parameter data or customising an analysis routine is easily done with user-friendly intuitive menus and a touch screen display.
The versatile analyser 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.
