Product Information


The Chemtrol 255 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 255 is a microprocessor-based digital controller designed to maintain both Free Chlorine (PPM) and water pH in commercial pools like hotels, motels, health clubs, condos, etc. 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. A key advantage of this sensor is that it is not affected by the use of any type of Cyanuric Acid stabilizers and/or oxidizers, thereby assuring constant Free Chlorine levels at all times. Extensive laboratory and field tests have shown it to be very accurate and reliable.

The Chemtrol 255 is also easy to install and simple to use. All the control functions are on the front panel. A bright LCD display shows ORP and/or pH readings, calibration adjustments, and alarm limits. The five LED lights indicate the operating modes (OFF, Manual or Auto), feed status, out-of-range alarms, and overfeed alarms. The front panel controls include set-point, calibration, low and high alarm limits, safety timer limit, and proportional feed adjustment. Feed control is either ON/OFF or Proportional. The Proportional Feed feature is particularly useful to avoid overfeeding in small bodies of water. It reduces the feed cycle time progressively as the sensor reading approaches the set-point.

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.

Why should you buy a Chemtrol pool chemistry controller?

Chemtrol controllers are installed globally across a wide range of applications, which attests to their reliability and effectiveness. These controllers are designed with a strong emphasis on product reliability, ease of use, and friendly customer service. 

Another significant benefit of Chemtrol pool chemistry controllers is their five-year electronics warranty. Few companies provide such an extended warranty for their products, which demonstrates the faith that Chemtrol has in its controllers. A warranty of this length guarantees long-term protection for your investment and gives you peace of mind that you're getting a top-quality product. 

Perhaps most importantly, Chemtrol controllers make pool maintenance a breeze. They allow for precise chemical and pH control, making it easier and more cost-effective to operate your pool. With Chemtrol's automatic controllers, you no longer have to waste time manually dosing chemicals, which can sometimes lead to inconsistencies and inefficiencies. This improves the overall water quality and ensures a pleasant and safe swimming experience for all users. 

Chemtrol pool chemistry controllers provide excellent value for your money, top-notch customer support, and easy-to-use features that make pool maintenance more manageable than before. With their extended warranty and global presence, it's no wonder that Chemtrol (manufactured by Santa Barbara Control Systems (SBCS)) remains one of the leading manufacturers of automatic controllers in the United States.
