Silica Analyzer monitors silica continuously in the range of 0-100 ppb. It alerts user to changes in silica levels in time for corrective action to be taken before significant downtime is incurred. The silica analyzer uses an all integrated and continuous monitoring using silico molybdate blue method for colorimetric measurement at a wavelength of 820 nm. They are available in panel or wall-mount version. It self-checks new calibration parameter and generates warning or alarm message if deviation from primary calibration parameter occurs. This analyzer also has a reagent and calibration solution through non-proprietary reagent as well as reagent with ceramic pulse pumps. The analyzer also detects performance deterioration of ion-exchange resin by measuring silica density in ultra-pure water.
