Electro-Chemical Devices TC80 Total Chlorine Analyzer

Click2Contact

The TC80 Total Chlorine Analyzer from Electro-Chemical Devices (ECD) is designed to eliminate consumables, simplify installation and reduce maintenance with a self-cleaning design, lowering the total cost of ownership.

Panel mounted and ready-to-go out of the box, the easy-to-use device monitors total chlorine in drinking water, industrial cooling and rinse water, wastewater or other freshwater samples containing chlorine in the range of 0–20 ppm. Its Total Chlorine Sensor (TCS) is a three-electrode amperometric sensor that measures all chlorine species in the water, combined chlorine and free chlorine in a range of 0.05–20 ppm Cl₂ (high range) or 0.005–2 ppm (low range).

The analyser’s plug-and-play design incorporates a flow control device, a pH sensor and the T80 transmitter mounted on a PVC panel. Simply connect the sample and drain lines, then the power and outputs, and it is ready to use. The product is calibrated at the factory before shipment, and additional calibrations are accomplished by DPD comparison.

The analyser’s sensor technology and automatic pH compensation offer a reagentless design to keep the cost of ownership low without having expensive reagents. It has automatic flow control and large flow tubes and cells, which reduces clogs and blockages and allows for easy cleaning.

The product includes dual 4–20 mA output, Modbus and/or HART communication and three alarm relay outputs. It can be powered from 24 VDC or 110/220 AC power. An auto cleaning option is available to keep the chlorine sensor clean from contaminants for an extended period of time.
