OAKTON is proud to present the 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.
