Chlorine Analyzers

Chlorination is employed in most water treatment processes to remove metallic ions and biological contaminants, and to suppress subsequent growth of bacteria and other biota.

The RC400G / the FC400G residual and free chlorine analyzers are high performance and accuracy systems with a microprocessor incorporated and are mainly used for the measurement of residual and free chlorine in water.

FC400G Free Available Chlorine Analyzer

The FC400G non-reagent free chlorine analyzer adopts the polarographic method using rotating electrode to continuously measure on-line the concentration of free available chlorine.

The FC400G is intended for measurements in the water distribution network, at pumping stations, water delivery points, schools, and public facilities.

FC500G Free Available Chlorine Analyzer

The Model FC500G is designed to measure free available chlorine without using reagent, and achieved a long maintenance period with electrode cleaning system.

The FC500G is intended for measurements in the water distribution network, at pumping stations, water delivery points, schools, and public facilities.

RC400G Residual Chlorine Analyzer

The RC400G residual chlorine analyzer employs a polarographic system using rotating platinum electrodes to provide continuous online measurement of residual chlorine concentration. By appropriate use of reagents, it is possible to separate residual chlorine (free chlorine+combined chlorine) from free chlorine for measurement.

The RC400G is mainly used for the measurements in municipal water treatment, industrial water supply facilities, and large-scale boilers.
