Walchem's pH/ORP on-line process controllers will improve your treatment performance. With a choice of two models, WDP (Dual pH/ORP) or WPH (Single pH/ORP), finding the optimum control for your application is a snap. Both the WDP and WPH are microprocessor-based with an easy-to-use menu format for programming. A versatile output configuration allows you to program up to four outputs in a variety of ways with just one controller. The WDP and WPH are available with either on/off mechanical relay outputs or direct pulse proportional control for metering pumps. Installation is as easy as unpacking the unit, mounting it and plugging it in. UL/CSA/CE certified.
