Features:

 The WiFi online pH ORP controller allows you to real time monitor the pH and ORP via your smartphone on the Tuya APP(for free), it is compatible with ios and Android system, perfect for 24 hours online monitoring.

 Widely used to test the pH / Temperature / ORP (Oxidation Reduction Potential) of water.

 With relay output power socket, you can control the pH & ORP value according to your requirements.

 You can replace the fuse easily and fast with external replacement. Detachable and replaceable pH and ORP electrodes.

 With dual power plug for air outlet stone, ozone generators, oxygen pumps, carbon dioxide regulators, solenoid valves and other ORP & pH control devices.

 Easy calibration of pH/ORP with just a mini-screwdriver and automatic temperature compensation.

 Clear LCD with backlight, 3 results displayed simultaneously. Easy to use and provide instant display of results.

 Test temperature in ℃ / ℉(switchable units) and can online monitor and control ORP & pH for a long time.

 Apply in water sources, soil-free growing, aquarium, hydroponics, laboratory, spas, environment water, swimming pools, water purification systems, etc.
