Electro-Chemical Devices TC-80 total chlorine analyser

Click2Contact

The TC-80 total chlorine analyser 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. Its plug-and-play design allows it to be installed right out of the box. Its panel mount design includes built-in flow control, which eliminates the need for complicated pressure regulators and rotameters.

The product incorporates a constant head flow control device, a pH sensor, a chlorine sensor and ECD’s T80 analyser/transmitter mounted on a PVC panel. By connecting the sample and drain lines, then connecting the power and outputs, the device is ready to use.

The TCA sensor is a three-electrode amperometric sensor with a gold cathode, silver halide anode and 304 stainless steel counter electrode. The pH sensor provides compensation for samples between pH 4 and pH 12.

Amperometric chlorine sensors are flow sensitive, so a constant head flow controller maintains the optimum flow by the sensor over a wide range of incoming sample flow rates.

The product is available with either 110–240 VAC or 24 VDC power and 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.

It is also available with an auto-clean option that includes a solenoid-actuated spray cleaner using either 30 psi process water or air.
