OAKTON is proud to present our highly versatile 1000 series pH/ORP
controller. Select from three control types. Use on/off control to shut
off your pump or valve when your process passes its set points. Use
pulse frequency or pulse length proportional control to gradually
increase or decrease your pump’s or valve’s response, depending on
the amount by which your process has passed the set point.
Customize your controller to fit your exact application! This unit is
selectable for pH or ORP (as mV or percent) control; 0-20 or 4-20 mA
scaleable, isolated recorder output; normally open or closed relays; and
manual or automatic temperature compensation. Controller also features a
safety Hold function, manual override of the relays, and resistance to
electrical signal input noise.
