PRODUCT SHOWCASE: pH&ORP DUAL-INPUT pH/ORP CONTROLLERS Walchem has introduced its new WDP400 SeriesDual-Input pH/ORP controllers. These versatile con- trollers are designed for a broad range of industrial, commercial, and municipal water treatment applica- tions. 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 and is more cost effective than two single- input models. Integrated data log- ging 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. All controllers are compatible with WEL Series pH/ORP electrodes, which offer an extremely reliable dif- ferential measurement technique that is immune to possible ground loop problems. In addition, all models meet UL, CSA, and CE standards for safety and performance, providing reliable operation in harsh industrial environments subject to electrical or radio frequency noise interference.

Circle 151 on reader service card REAGENT CONTROL SYSTEMS Water Specialists Technologies' Reagent Control Systems are designed to monitor wastewater for controlling the addition of reagents to achieve predetermined process set points. These systems eliminate oper- ator guesswork when adding chemi- cals to waste streams, thereby prevent- ing the under- or over-dosing of reagents, even under fluctuating con- ditions. Specific application elec- trodes, immersed in the solutions, continuously signal their respective controllers that monitor these signals 54 I metalfinishing I October2009 and control the addition of reagents on a real-time basis. Th e un if o rm , reli- able process monitorin g and control en sures consistent results and a sig- nific ant reduction in chemical usage and costs.
