    Automatic pH and EC controller for monitoring nutrient solution acidity and conductivity in hydroponics and greenhouses. Supply 110–240 V AC.

  • Product description

    Automatic pH and EC controller for hydroponics and greenhouses, 110–240 V AC

    This automatic pH and EC controller is designed to monitor nutrient solution quality in hydroponic systems and greenhouses. pH shows the acidity of the solution, while EC (electrical conductivity) indicates the amount of dissolved nutrients. The controller is supplied with 110–240 V AC, so it suits the EU 230 V grid.

    ⚠ Output type, measuring ranges and package contents (electrodes, dosing pumps) are not stated in this description. Please check with us before ordering.
    Key idea:
    In hydroponics plants receive nutrients only from the solution, so a pH or EC deviation quickly affects the yield. An automatic controller continuously monitors both values and helps keep them in range without constant manual measurement. This saves time and reduces the risk of errors.

    Supply
    110–240 V AC
    Purpose
    hydroponics, greenhouse

    Operating principle

    The pH electrode measures the activity of hydrogen ions in the solution: pH 7 is neutral, lower is acidic, higher is alkaline. The EC electrode measures the electrical conductivity of the solution, which increases with the amount of dissolved salts and fertilisers.

    The controller compares readings with the set limits and automatically controls connected devices – for example acid, base or nutrient dosing. Check the exact number and type of outputs before ordering.

    For accurate measurement the pH electrode must be calibrated periodically with buffer solutions, and EC measurement is affected by solution temperature.

    Why choose an automatic pH and EC controller?
    It replaces daily manual measuring and adjusting. Stable pH and EC help plants absorb nutrients better, while automation reduces fertiliser overuse and the chance of human error.

    Technical specifications

    Product type Automatic pH and EC controller
    Manufacturer Not specified
    Measured parameters pH, EC (electrical conductivity)
    Purpose hydroponics, greenhouses
    Supply 110–240 V AC

    Main functions

    • pH measurement – solution acidity control
    • EC measurement – nutrient concentration control
    • Automatic control – keeping values within set limits
    • Continuous monitoring – no need for daily manual measurement
    • Wide supply range – 110–240 V AC
    • For hydroponic systems – NFT, DWC, drip and similar systems

    How does it differ from similar products?

    Handheld pH / EC meter Only shows the value when you use it. An automatic controller monitors continuously and controls by limits.
    Separate pH controller Controls acidity only. This controller monitors both pH and EC.
    Timer-based dosing Doses by time without knowing the actual state of the solution. The controller reacts to real measurements.

    Where is it used?

    • Hydroponic systems
    • Greenhouses with irrigation units
    • Vertical farms
    • Aquaponic systems
    • Seedling and microgreens growing
    • Nutrient solution tanks and reservoirs

    Use by need

    Beginner.
    Immerse the electrodes in the solution tank, connect the 230 V supply and set the required pH and EC limits for the crop.
    Experienced installer.
    Install the electrodes where the solution mixes well, and the dosing point away from the electrodes so that the measurement is not distorted.
    Energy engineer / designer.
    When designing, consider tank volume, dosing rate, electrode maintenance and the calibration schedule.

    Practical use

    Tomatoes are grown in a greenhouse hydroponic system with a common solution tank. Previously pH and EC were measured manually once a day, so values drifted at weekends. With an automatic controller installed, the solution is monitored continuously and deviations are corrected without waiting for a person.

    Pros / advantages

    • pH and EC in one controller
    • Automatic value maintenance
    • Less manual work
    • 110–240 V AC supply suits the EU grid
    • Suitable for various hydroponic systems

    Cons / limitations

    • Manufacturer and detailed technical data are not specified
    • Electrodes require regular calibration and maintenance
    • pH electrodes have a limited service life and must be replaced
    • Output type and package contents are not confirmed in this description

    Safety and installation notes

    • ⚡ The controller is supplied with 110–240 V AC. Fixed wiring must be done by a qualified electrician with the power switched off.
    • ⚡ Install the controller in a dry place above the solution level so that water cannot reach the housing or connectors.
    • Protect the supply circuit with a residual current device (RCD), as the equipment operates near water.
    • Store pH adjustment acids and bases according to the manufacturer's instructions and work with gloves and eye protection.
    • Do not let the pH electrode dry out – keep it in the solution specified by its manufacturer.

    Quick selection guide

    Automatic
    110–240 V AC
    Hydroponics
    Suitable when you need:
    • to monitor nutrient solution pH and EC continuously
    • to reduce manual measuring and adjusting
    • to automate a hydroponic system in a greenhouse
    Check before choosing:
    • which electrodes and pumps are included
    • the output type and number
    • measuring ranges for your crops
    • electrode calibration and replacement needs
    Important reminder: The controller is only as accurate as its electrodes: without regular calibration and maintenance even automation will maintain inaccurate values.

    FAQ

    What do pH and EC measure?
    pH shows the acidity of the solution, EC the electrical conductivity, which indicates the amount of dissolved nutrients.
    What is the supply voltage?
    110–240 V AC – suitable for the EU 230 V grid.
    Are electrodes included?
    Package contents are not stated in this description. Please check with us before ordering.
    How often should the pH electrode be calibrated?
    Regularly, with buffer solutions according to the electrode manufacturer's instructions. Frequency depends on intensity of use.
    Does temperature affect measurement?
    Yes, the EC value depends on solution temperature, so check whether the controller has temperature compensation.
    Is it suitable for aquaponics?
    pH and EC control is also useful in aquaponics, but dosing must be matched to the needs of the fish.
