The CHEMTROL® 255 is the only easy-to-use controller offering Free Chlorine and pH control for pools, spas, cooling towers, industrial water treatment, etc.
The Chemtrol CH255 Digital Controller introduces the new sensor for Free Chlorine control in automated water treatment.
A microprocessor-based digital controller, it is designed to maintain both free chlorine PPM and water pH in high-end residential pools, small commercial pools and spas and light industrial applications.
Unlike other chlorine sensors on the market, these sensors are easy to installl and maintain, very precise and so reliable that they are covered by a full 2-year warranty.
For better water management results, it is recommended to use ORP control of chlorine oxidizing activity and PPM monitoring of free chlorine. Alternatively, PPM control can be used for control of the sanitizer and ORP control for an oxidizing agent, such as ozone.
