The ECD FC80 Reagentless Free Chlorine Analyzer provides accurate, low-maintenance monitoring of free (residual) chlorine without the use of chemical reagents. Designed to measure free chlorine across low and high ranges up to 20 ppm, it ensures reliable performance in drinking water, industrial, and wastewater applications. Its fully integrated, panel-mounted plug-and-play design allows for quick installation and immediate operation. Factory-calibrated and easily verified using the DPD comparison method, the FC80 delivers dependable chlorine measurement with minimal setup and maintenance.
- No Reagents Required: the FC80 Free Chlorine Analyzer sensor technology and automatic pH compensation is a reagentless design and keep the cost of ownership low without having expensive reagents.
- Compliant with EPA Method 334.0
- Automatic Flow Control and Large Flow Tubes and Cells: greatly reduces clogs and blockages of the analyzer which is a common problem in other free chlorine analyzers and allows for easy cleaning.
- Panel Mounted System Plumb and Play Design: the Free Chlorine Analyzer comes complete and is easy to install and ready to use.
- T80 Analyzer Capability: TDual Masurements (2) 4 to 20 mA output, MODBUS and/or HART communication, (3) Alarm Relays, 24 VDC or 110/220 AC Power.
- Auto Cleaning Option: The FC80 Free Chlorine Analyzer can be ordered with an auto cleaning option to keep the chlorine clean from comtaminates for an extended period of time.
