For years, Walchem has offered the WebMasterONE control in conjunction with Turner Designs Little Dipper online fluorometer, to accurately measure and control the concentration of scale or corrosion inhibitors in cooling tower and boiler applications. Now the Opti-Check fluorometer is available to ensure that the calibration of the online sensor is accurate. A low cost PTSA version, and an affordable PTSA/Fluorescein version, is available.
The Opti-Check handheld fluorometer requires low maintenance, is easy to use, and comes in a durable dustproof, watertight (IP 67) package. The product is sensitive to less than 1 ppb of fluorescent dye and provides better control of treatment chemicals.
Walchem has introduced the WDP400 Series Dual Input pH/ORP controllers. These controllers are designed for a broad range of industrial, commercial, and municipal water treatment applications. WDP controllers accept two electrode signals, in any combination of pH and ORP, and are offered in a convenient pre-wired NEMA 4X wall mount package that can be installed in minutes. The dual input model reduces space requirements. Integrated data logging is available to validate system performance. A USB stick is all that’s needed to extract data and event logs that include electrode measurements, temperature, accumulated chemical feed, and relay activation times.
