pH 800 CONTROLLER OVERVIEW
 |
The pH 800 controller provides ±0.01 pH accuracy for
reliable, easy-to-use on/off control of your pH and mV process. Two
separately programmable relays are ideal for acid feed/base feed
applications. Use the isolated 4-20 mA output to send data to your recorder
or data acquisition system for hard copy reports.
Customize your
controller to fit your exact application! This unit is selectable for pH or
ORP (mV) control and manual or automatic temperature compensation. The 1/4
DIN size fits into standard panel cutouts. IP54 rated front panel keypad is
weather resistant. Mounting hardware included.
