4-20 mA output
Allows the signal to be read by PLCs and dataloggers. Standard pH probes output a mV signal. Sometimes though a 4-20 mA ouptut is more useful for integrating into PLCs or our own multi-channel datalogger. The pH is displayed on the screen of the electronics module. The sensing probe is replaceable.

pH and ORP Controllers Combined
Two independent controllers in the same enclosure. Data logging ports built in on the inside of the enclosure.
It is essentially two single units combined into one unit. One stack light for pH and the other for ORP.
