Chlorine Analyzer eliminates pH sampling systems, reagents.
April 22, 2009 -
Featuring built-in pH compensation (4-12) and plug-and-play design, TCA-22 is suited for testing drinking water, industrial cooling and rinse water, wastewater, or other fresh water samples containing 0-20 ppm chlorine. Amperometric sensor has 3-electrode design, which measures all chlorine species in water, combined chlorine and free chlorine. While counter electrode provides stable base potential, constant head flow control device design maintains optimum flow over 10-80 gph range.

New Plug-n-Play TCA-22 Total Chlorine Analyzer Eliminates pH Sampling Systems & Reagents
Ideal For Municipal and Industrial Water/Wastewater Treatment
Yorba Linda, CA-April 7, 2009-The measurement and control of Total Chlorine has never been easier or more economical than with the new TCA-22 Analyzer System from Electro-Chemical Devices, Inc., which features built-in pH compensation in a virtually plumb-and-play design that make it ready to go right out of the box.
The Model TCA-22 is a Total Chlorine Analyzer, which is designed for use in drinking water, industrial cooling and rinse water, wastewater or other fresh water samples containing chlorine in the range of 0-20 ppm. It is ideal for application in municipal water systems and a wide range of water-based processes in the chemical, electronics, electric power, food/beverage, oil/gas, pharmaceutical, pulp/paper and many other industries.
The TCA-22's advanced total chlorine amperometric sensor features a built-in pH sensor that automatically compensates for samples with a 4 to 12 pH concentration. This capability eliminates the need for expensive sample conditioning systems with consumable reagents to control the pH level in the solution. There's also no maintenance labor required to monitor and replace the reagents.
The TCA-22's amperometric sensor is a three electrode design, which measures all chlorine species in the water, combined chlorine and free chlorine. The sensor is constructed with one gold cathode, one silver halide anode and a 304 stainless steel counter electrode. The counter electrode provides a stable base potential that minimizes drift for high accuracy.
The TCA-22 sensor's micro-porous membrane allows ions to diffuse in and out of the sensor. The various chlorine species in the measured sample diffuse into the sensor and react with the acidic potassium iodide electrolyte to form iodine. The iodine is reduced at the cathode back to iodide and the current flow between the cathode and silver iodide anode is proportional to total chlorine.
While amperometric chlorine sensors are flow sensitive, the TCA-22 features a constant head flow control device (ECD) design. It maintains the optimum flow by the sensor over a wide range of incoming sample flow rates from 38 to 300 L/hr (10 to 80 gal/hr). It operates over a wide temperature range from 0 to 45°C (32 to 113°F).
The TCA-22's built-in C22 Analyzer allows either total chlorine or pH to be displayed graphically. User defined ranges allow easy trend analysis of either parameter. The C22 features a 2.5-x-1.75 inch LED display for local monitoring with simple menu's and membrane switches for easy use.
The panel mount design of the TCA-22 comes pre-wired and with assembled flow tubing. ECD's advanced sensor and controller technologies allow installation and commissioning to be completed in just three easy steps utilizing simple tools. All that is necessary is to connect the sample and drain lines, connect the power and outputs and the TCA-22 is ready to use. Calibration is accomplished by DPD comparison.
