Dual monitoring of pH and ORP in large LED display and
single control of either pH or ORP. Highly accurate.
Digital pH-ORP controller with large size LED display for
easy reading.
High input impedance avoid measuring error.
Built in SLOPE and CAL. 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.
