Product Information


The Chemtrol PC2100 pH/ORP Controller is a reliable yet simple programmable controller that features automatic maintenance of water chemistry (ORP and pH) with a display of the Langelier Saturation Index. It is an upgrade of the Chemtrol PC2000 controller with new, improved electronics, a large 8-line screen display, and a USB port for easy datalog download. The PC2100 features a flow cell assembly, sensor cleaning, remote alarm, and several other features. This unit includes the controller, respective probes (pH and ORP probe), safety flow switch, FCA flow cell assembly, PPM cell, and miscellaneous plumbing supplies.

The PC2100 Main Screen on the 8-line display enables the operator to supervise all process functions at a glance and to quickly respond to any changing condition. It operates like a computer with multi-line screen displays and direct access to all menus and submenus. The front panel keypad is used to move up and down each menu and enter or exit the submenus. All operating functions can be easily modified from the keypad, including sensor calibration, control set-points, alarm levels, and the programs for super chlorination and chemical savings.

There are additional options available which can be added to this controller as a separate purchase. These options include the Free Chlorine sensor for ppm readouts, conductivity (or TDS) control, programmable heater control, and tank level and flow monitoring. You can also add full remote duplex capability with the CHEMCOM communications package (sold separately). Any number of facilities can be monitored either by remote computer or by telephone. This allows real-time supervision by management and remote troubleshooting by CHEMTROL technical support. The Communications Package is item #PCx-ETHCOM.

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.
