Chemical Controllers & Automation

The CHEMTROL 255 PPM/pH Controller introduces a long-awaited technological breakthrough in automated water treatment with a proprietary new sensor for Free Chlorine. A microprocessor-based digital controller, it is designed to maintain both chlorine PPM and water pH in high-end residential pools, small commercial pools and spas and light industrial applications. Ships FOB Factory. 

 The 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. A significant advantage of this sensor is that it's not affected by cyanuric acid (CYA) stabilizer 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.

This sensor gives the operator precise and reliable control of Free Chlorine under the most difficult conditions. The CHEMTROL 255 is the only easy-to-use controller offering True Free Chlorine and pH control for pools, spas, cooling towers, industrial water treatment, etc.  

Includes controller, electrodes, & safety switch. 

Please see the the Chemtrol Flow Assembly for a pre-assembles flow switch.

Designed for affordability, simplicity of installation, ease of use and long-term reliability, it includes features normally not found on this type of controller, such as:

•  Adjustable setpoints,
•  Adjustable high and low alarms,
•  Adjustable overfeed safety timers and
•  Adjustable proportional feed control.

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
•  Waterproof Cabinet with Clear Window Cover
•  5-year Electronics Warranty
•  Toll-Free Technical Support 

Unlike conventional amperometric or colorimetric sensors, the PPM sensor is easy to install and operate. It does not require a special pressure flow cell and/or expensive and expendable chemical reagents. And best of all, it is maintenance free.
