PRODUCT SHOWCASE:pH&ORP

DUAL-INPUT pH/ORPCONTROLLERSWalchem has introduced its newWDP400 SeriesDual-Input pH/ORPcontrollers. These versatile con­trollers are designed for a broad rangeof industrial, commercial, andmunicipal water treatment applica­tions. WDP controllers accept twoelectrode signals, in any combinationof pH and ORP, and are offered in aconvenient pre-wired NEMA 4X wallmount package that can be installedin minutes. The dual-input modelreduces space requirements and ismore cost effective than two single­input models. Integrated data log­ging is available to validate systemperformance. A USB stick is all that'sneeded to extract data and event logsthat include electrode measurements,temperature, accumulated chemicalfeed, and relay activation times.

All controllers are compatible withWEL Series pH/ORP electrodes,which offer an extremely reliable dif­ferential measurement technique thatis immune to possible ground loopproblems. In addition, all modelsmeet UL, CSA, and CE standards forsafety and performance, providingreliable operation in harsh industrialenvironments subject to electrical orradio frequency noise interference.For more information, call (508) 429­1110, e-mail info@walchem.com. orvisit www.walchem.com.

REAGENT CONTROL SYSTEMSWater Specialists Technologies'Reagent Control Systems aredesigned to monitor wastewater forcontrolling the addition of reagentsto achieve predetermined process setpoints. These systems eliminate oper­ator guesswork when adding chemi­cals to waste streams, thereby prevent­ing the under- or over-dosing ofreagents, even under fluctuating con­ditions. Specific application elec­trodes, immersed in the solutions,continuously signal their respectivecontrollers that monitor these signals
