Model : 3679N pH, ORP In-line Controller

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
