Reagentless Chlorine Dioxide Analyzer: The ECD CD80 Chlorine Dioxide Analyzer is a panel mounted, ready to use Chlorine Dioxide Analyzer. It is designed to monitor Chlorine Dioxide (ClO2) in drinking water, industrial cooling and rinse water, wastewater or other fresh water samples containing chlorine dioxide in the range of 0.05 to 20 ppm. The CD80 Chlorine Dioxide Analyzer features a plug and play design that incorporates a flow control device, a chlorine dioxide sensor and the T80 transmitter that are conveniently mounted on a PVC panel. Connect the sample and drain lines, connect the power and outputs and it is ready to use.
- No Reagents Required: the DC80 Chlorine Dioxide Analyzer sensor technology is a reagentless design and keeps the cost of ownership low without having expensive reagents.
- Automatic Flow Control and Large Flow Tubes and Cells: greatly reduces clogs and blockages of the analyzer which is a common problem in other total chlorine analyzers and allows for easy cleaning.
- Panel Mounted System Plumb and Play Design: the Chlorine Dioxide Analyzer comes complete and is easy to install and ready to use.
- CD80 Total Chlorine Analyzer Capability: (2) 4 to 20 mA outputs, MODBUS and/or HART communication, (3) Alarm Relays, 24 VDC or 110/220 AC Power.
- Auto Cleaning Option: The CD80 Chlorine Dioxide Analyzer can be ordered with an auto cleaning option to keep the chlorine sensor clean from contaminates for an extended period of time.
