ECD TC-80 Total Chlorine Analyser

The TC-80 Total Chlorine Analyser from Electro-Chemical Devices (ECD) monitors total chlorine in drinking water, rinse water, cooling water and other freshwater samples, from 0.05–20 ppm chlorine as the standard range or 0.005–2 ppm with the low-range sensor.

The plug-and-play device incorporates a constant head flow control device, a pH sensor, a chlorine sensor and ECD’s T80 analyser/transmitter mounted on a PVC panel.

The sensor is a three-electrode amperometric sensor with a gold cathode, silver halide anode and 304 SS counter electrode. The pH sensor provides compensation for samples between pH 4 and pH 12, eliminating the need for sample conditioning systems.

The flow controller maintains the optimum flow by the sensor over a range of incoming sample flow rates. The minimum flow required is 38 L/h and the maximum flow rate is 302 L/h, with the sample going to drain at atmospheric pressure.

The analyser is available with either 110–240 VAC or 24 VDC power. The device graphically displays both the total chlorine and pH, allowing for easy trend analysis. The standard configuration has two 4–20 mA outputs and three alarm relays.

An auto clean option includes a solenoid actuated spray cleaner using either 2 bar process water or air. A timer controls the period and duration of the cleaning cycle.
