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 Control System for Nuetralization Tank
This system allows the pH controller to make additions only if the temperature is within range (since the nuetralization is exothermic) and also if the level is within the range between the level probes. If both these conditions are met then the pH controller is allowed to make additions. (although won’t necessarily make additions unless requried)
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.
