Description
1/ 4 DIN panel mount pH/ ORP controller/ transmitter with dual SPDT Hi/ Lo relays, manual set points and calibration are via potentiometers. Features a 4-20 mA current output and has an external pH/ ORP select switch. Display is a large LCD. Connectors are a BNC and spade lug screw type connector blocks. Meter requires a Pt-100 ATC or a simulation resistor for temperature. Power 115/ 230V AC.
