3 in 1 pH/EC/TEMP Water Quality Detector Professional pH Controller with Relay Plug Repleaceable Electrode BNC Type Probe Water Quality Tester for Aquarium Hydroponics Tank Monitor 14.00pH 1999us/cm 19.99ms/cm ( Item#: E5169EU )

This pH/temperature/EC 3-in-1 water quality controller has pH&TEMP&EC tri display and pH control which can simultaneously measure and display pH/temperature value and electric conductivity(EC). It has BNC electrode(pH) and 1 output power socket. The pH electrode is removable and can be replaced at any time. With relay output power socket, you can plug your own 110V/220V equipment, such as air outlet stone, oxygen pumps, carbon dioxide regulators, solenoid valves and other pH control devices. Simply set the desired Hi/Low pH value in the controller. If the pH value currently measured is lower than the set value, it will open the device. If the measured value is higher than the set value, it will close the device. Suitable for aquarium pool, soil-free growing, laboratory, and environment water.

Features:
Widely used to test the pH / Temperature / EC (electric conductivity) of water.
With relay output power socket, you can control the pH value according to your requirements.
You can replace the fuse easily and fast with external replacement. Detachable and replaceable pH electrode.
With power plug for air outlet stone, oxygen pumps, carbon dioxide regulators, solenoid valves and other pH control devices.
Test the EC with both us/cm and ms/cm units at will.
Easy calibration of pH/EC 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 pH for a long time.
Apply in water sources, soil-free growing, aquarium, hydroponics, laboratory, spas, environment water, swimming pools, water purification systems, etc.
