Digital pH/ORP Controller
Product Description
- Dual monitoring of pH and ORP in large LED display and single control of either pH or ORP.
- High input impedance avoid measuring error.
- Adjust knob, easy for single point or two points pH calibration.
- “pH – ORP” control, the relay “pH” when measuring value is above the set point for pH.
- And the relay “ORP” when measuring value is below the set point for ORP.
