• 2-in-1 Water Quality Tester: 2-in-1 pH and ORP Controller measures and displays both pH value and redox value (ORP), comes with a BNC socket electrode and two output power sockets.
• Instant Measurement: Dual measurement display shows pH value at 0.00 to 14.00pH and ORP value at -1999 to 1999mV simultaneously. No need to press any button to change the measurement you wanted to observe.
• Detachable Electrode: 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, simply set the desired Hi/ Low pH/redox values in the controller.
• Relay Output Power Control: Plug in your own device (e.g. oxygen pump, CO2-regulator, O3 ozonizer, or other pH & ORP generation devices) into the corresponding PH or ORP output power socket, you can set your desired ph or ORP value in this monitor controller to trigger your devices to turn on or off.
• Wide Applications: Ideal for anywhere that requires water quality monitoring, e.g fish hatchery, wine production, swimming pool (bath), laboratories, water conditioning, schools & colleges, floristics, for analysis of fluids (ph-value), ponds, various industrial, etc.
