TCA-22 is a Total Chlorine Analyzer, and is designed for testing drinking water, industrial cooling and rinse water, wastewater or other fresh water samples containing chlorine. The TCA-22's amperometric sensor is a three-electrode design, which measures all chlorine species in water, combined chlorine and free chlorine. A micro-porous membrane allows ions to diffuse in and out of the sensor. The unit offers built-in pH compensation, and maintains the optimum flow by the sensor over a wide range of incoming sample flow rates, and over a wide temperature range. The built-in analyzer allows either total chlorine or pH to be displayed graphically and features a 2.5- by 1.75- inch LED display for local monitoring with simple menus and membrane switches for easy use. Unit comes pre-wired and with assembled flow tubing. Installation and commissioning can be completed in three steps using simple tools.
