CHLORINE ANALYSIS MADE SIMPLE CHEMTROL® CH265 PPM/pH Digital Controller introduces the new PPM Sensor for Free Chlorine control. A microprocessor-based digital controller, designed to maintain both free chlorine (PPM) and water pH in Municipal Water, Well Water, Waste water and Industrial applications. No Reagents No Maintenance No Pressure Regulator. Free CL Range 0.00 to 10.0 PPM pH Range 0.0 – 14.0 Programmable 4-20 mA output to PID and/or Chart Recorder Programmable 4-20 mA Output Control with Adjustable Setpoint Dry Contact Remote Alarm STANDARD FEATURES Easy to install Simple to use All Control Functions on Front Panel Separate Adjustable Setpoints Separate Adjustable Alarms Acid/Base Selector Proportional Feed with Adjustable Bandwidth Separate Adjustable Overfeed Safety Timers Rain and Splash Proof Cabinet 5-year Electronics Warranty PRECISE AND RELIABLE PPM READING The new Free Chlorine Sensor is a solid state sensor with a selective membrane that provides direct readings of Free Chlorine in water at concentrations ranging from 0.1 to 10 ppm (parts per million) or mg/l (milligrams per litter). These are true readings of Free Chlorine corresponding to the DPD #1 test. A significant advantage of this PPM sensor is that it’s not affected by cyanuric acid (CYA) stabilizer and/or oxidizers, thereby assuring constant Free Chlorine levels at all times. Unlike other chlorine sensors on the market, this new sensor is easy to install and maintain and gives the operator precise and reliable control of Free Chlorine under the most difficult conditions. The PPM sensor is covered by a full 2-year warranty.
