Description
1/ 4 DIN panel mount pH/ ORP controller/ transmitter in a waterproof IP-65 enclosure. Features, LCD display, dual SPDT Hi/ Lo relays, manual set point adjust and pH calibration via potentiometers. For ORP there is a Zero Adjustment and pH/ ORP is selectable via a shorting plug. Output is 4-20 mA current type. Connectors are a spade lug circular connector for pH+ . All other connections are tinned leads to terminal blocks. Temperature compensation is a Pt-100 ATC or simulation resistor. Power 115/ 230V AC.

* Dual function pH & ORP
* Orp zero point calibration
* Isolated 4~ 20ma output
* Dual on/ off relays
* Auto temperature compensation
* Water & corrosion proof case
* Large led display
