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 ).
