Portable residual chlorine data logger

Gathering data on residual chlorine concentrations in remote parts of water distribution systems is increasingly important.  Accurate data over extended periods provides the information needed to ensure at least minimum disinfectant levels in all parts of a system.  Until now, temporary chlorine residual measurement systems required the installation of standard chlorine monitors with high sample flow requirements, power connections, and separate data recording hardware. ATI has developed the “ChlorLog” to provide a compact, stand-alone measurement and logging system that can be used virtually anywhere. Sensor, electronics, data logger, and flowcell are combined in one assembly. All that’s needed is sample connection. Even sample flow control is included as part of the flow assembly.
