Digital pH/ORP Controller

Product description: 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. A wide range of test and control, with high accuracy. Detection electrode with high performance, long-term monitoring and control of the pH value of the water, redox value.
AC voltage, 110V ~ 240V is optional.
There are two kinds of tests and test and control function selection. This product has a long-term test PH value of the aquarium, etc., when the PH value is higher or lower than the set value, the automatic power supply for other devices, such as CO2 began to supply CO2 solenoid valve connected equipment.
