WDP/WPH Series pH/ORP Controllers
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.

pH/ORP Preampifier
|
|
What do you do when your favorite pH/ORP electrode isn't available with a built-in preamplifier, but you need to send the signal a few hundred feet? Hook up to this external preamp and you can go 1000 feet if necessary! Compatible with all of Walchem's controllers (but not the W-130/230 series monitors L ).
