Electro-Chemical Devices' CA-6 Online Analyzer uses colorimetric technology to perform silica measurements
Electro-Chemical Devices' CA-6 Online Analyzer uses colorimetric technology to perform silica measurements. The CA-6 Analyzer is available in models measuring silica at 0-1.0 mg/L, 0-10.0 mg/L or 0-60 mg/L. It can also utilize photometric differential absorbance to analyze 20 other parameters in addition to silica, including: aluminum, phosphate, nitrogen, iron and sulfate. It operates at a temperature range of 5-50° C and offers repeatability of ±2% on the absorbance value if the turbidity <80 NTU and drift of ±2% per month on the absorbance measurement.
The CA-6 online sequential sampling analyzer weighs less than 40 pounds and can be wall mounted or set on a bench using the optional Bench Top Stand. After the sample, waste and reagent lines have been connected to the analyzer and provided with power, the CA-6 will begin its preprogrammed analysis sequence. The CA-6 is available with up to 4 channels (optional,) each from a separate sample point.
The CA-6 Analyzer features a touch-screen display that shows the measured parameter, analyzer status, percent reagent volumes, time and the menu bar, which provides access to the Run, Display, Program, Service and Help menus. It includes two alarm relay outputs and a 4-20 mA channel that connects with PLC’s or distributed control systems.
The CA-6 is enclosed in an epoxy powder coated, cold rolled steel cabinet and features two separate compartments to isolate liquids and electronics. The liquids enclosure houses all the components necessary for sampling and reagent flow, mixing and reaction stages (sampling pump, reagent micro-pumps and colorimetric reaction cell). The electronics enclosure contains the main power supply, the controller printed circuit board assembly and the touchscreen interface.
