Description
1/4 DIN panel mount pH/ORP controller/transmitter in a waterproof IP65 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 115/230 VAC.
- Dual function pH & ORP
- Orp zero point calibration
- Isolated 4 ~ 20 mA output
- Dual on/off relays
- Auto temperature compensation
- Water & corrosion proof case
- Large LCD display
