Colorimetric Analyzer Provides Reliable Iron Monitoring

The CA-6 colorimetric iron analyzer is an online sequential sampling analyzer that automatically performs a controlled sequence of sampling, analysis, and results processing. The analyzer uses the differential photometric absorbance method to measure trace amounts of iron in water. It relies on an LED light source and a heated colorimetric cell. Three measurement ranges are available depending on the chosen cell size: 2–250 ppb (26-mm cell), 9–500 ppb (16-mm cell), and up to 10 mg/L with an internal dilution module. The analyzer displays measured values and status information on a graphic touchscreen interface. The device can operate in temperatures from 41°F to 113°F.
