Product Information


The Chemtrol 265 PPM/pH Digital Controller features Santa Barbara's new Chlorine Sensor for Free Chlorine that gives easy-to-use, direct and reliable readings of Free Chlorine concentration in pool water. The Chemtrol 265 is a microprocessor-based digital controller designed to maintain both Free Chlorine (PPM) and water pH in commercial pools like hotels, motels, health clubs, and municipal pools, and municipal water plants as well as well water. The controller is compatible with all common sanitizers and has long-term reliability. This unit includes the controller, respective probes (pH probe and PPM probe), paddle wheel flow switch, FCA flow cell assembly, PPM cell and miscellaneous plumbing supplies.

The new PPM 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 and not approximate values derived from ORP readings. Unlike other chlorine sensors on the market, this sensor is simple to install and highly reliable. It does not require expensive reagents and is compatible with cyanuric acid (CYA) at all concentrations. It is so reliable that the sensor carries a two-year warranty.

The Chemtrol 265 Free Chlorine Analyzer automatically maintains both Free Chlorine concentration and pH of the water. All operating functions are clearly labeled and accessible from the front panel, with safety and easy-reset features not found on other controllers.

The Free Chlorine concentration can be adjusted from 0.0 to 10 ppm (or mg/l) based on local Health Department regulations for prevention of germs and bacteria (or from 0.01 to 3.00 for low chlorine level applications). The pH control level can be adjusted from 6.0 to 8.0. The standard pH control level is 7.5. Below 7.4, the water is too acidic and causes corrosion. Above 7.6, it is too alkaline and causes scaling, stains and reduced sanitizer efficiency.

All CHEMTROL controllers are user-friendly, reliable and easy to install and operate. Every unit is supplied with a comprehensive operation manual and a FIVE-YEAR electronics warranty.
