Digital PH ORP Meter 2 In 1 Controller Monitor w/ Output Power Relay Control Electrode Probe BNC for Aquarium Hydroponics Plants

Features: This 2-in-1 PH & ORP controller and monitor simultaneously measures and displays both PH value and redox value (ORP). It comes with 2 BNC electrodes (PH and redox) and 2 output power sockets. Both electrodes are detachable, they can be replaced easily at any time. As for the relay output power sockets, you can plug in your own 110V/ 220V device to it, e.g. air outlet stone, O3 ozoniser, oxygen pump, CO2-regulator, electromagnetic valve and other ORP & PH control devices. Simply set the desired Hi/ Low PH/redox values in the controller. It will turn on your device if the currently measured PH or Redox value is lower than your set value, and it will turn off your device if the measured value is higher than your set value. Specification: Measuring range PH: 0.00 ~ 14.00PH ORP: -1999 ~ 1999mV Accuracy PH: 0.1%+0.02PH ORP: 5mV Resolution PH: 0.01PH ORP: 1mV Set Range PH: 3.50 ~ 10.50PH ORP: -500 ~ 500mV Relay Contact: 5A for AC 110V or 220V Environment Operation Temperature : 0 to 50 C (32 to 122 F) Ambient Humidity : 90 or less than 90 % R.
