ChemTrol CH255 PPM/pH Digital Controller with Sensor

CHEMTROL® 255 PPM/pH Digital Controller introduces the new Sensor for Free Chlorine control. A microprocessor-based digital controller, designed to maintain both free chlorine (PPM) and water pH in Residential Pools and Spas, Commercial Pools and Spas, Hotels, Motels, Health Clubs, Apartments Buildings, Condo associations and Industrial Water Treatment.
Simplicity of installation, Compatible with all common sanitizers and oxidizers, ease of use and long-term reliability.

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 liter). 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 https://sbcontrol.com/probes-selection/ppm-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.
