    Q1: How to replace the electrode head of the SISCO digital pH meter?
    A1: Replacing the electrode head of the SISCO digital pH meter typically involves a few simple steps:

    1. Pull off the electrode cap directly, do not rotate to avoid damaging the electrode sensor.
    2. Unscrew the electrode fixing ring counterclockwise.
      Pull out the electrode head, do not rotate to avoid damaging the circuit.
    3. Align the two electrode grooves and push the electrode head into the main unit.
    4. Tighten the electrode fixing ring by rotating it clockwise.
      Put on the electrode cap, do not rotate to avoid damaging the electrode sensor.

    Q2: How to calibrate the SISCO digital pH meter?
    A2: Calibrating a digital pH meter like the SISCO model typically involves a few steps. Here's a general guide:

    1. Calibration is required for first-time use, battery replacement, and electrode replacement to ensure the accuracy of the 
      test. It is recommended to calibrate the meter every 2-4 weeks for optimal accuracy.
    2. Buffer solutions should be stored away from light and at low temperatures. Do not reuse buffer solutions, and discontinue use if there are any precipitates or spots in the buffer solution.
    3. Rinsing the electrode sensor before immersing it into the next buffer solution each time can improve calibration and testing accuracy.

    Q3: How to replace the digital pH meter battery?
    A3: Replacing the battery in a digital pH meter typically involves the following steps:

    1. Turn counterclockwise to remove the top cover.
    2. Push open the battery compartment cover.
    3. Remove the old battery and insert the new one (recommended to use 7# AAA alkaline dry battery).
    4. Close the battery compartment cover.
    5. Turn clockwise to tighten the top cover.

    Tips: What should I do if the battery leaks or corrodes inside the pen pH meter?

    If the battery in your pH meter leaks or corrodes, it's important to take action promptly to prevent further damage to the device. Here's what you should do:

    1. Safety first: Before handling the device, ensure that you're wearing gloves and protective eyewear, especially if the battery has leaked corrosive material.
    2. Remove the battery: Carefully remove the battery from the pH meter using gloves to avoid direct contact with the corrosive substance. Be cautious not to spill the leaked material onto other parts of the device.
    3. Clean the battery compartment: Use a cotton swab or cloth dampened with vinegar or lemon juice to clean the battery compartment and remove any corrosion. Ensure that the compartment is completely dry before inserting a new battery.
    4. Dispose of the old battery safely: Dispose of the leaked or corroded battery properly according to local regulations for hazardous waste. Do not throw it in the regular trash.
    5. Inspect for damage: Check the inside of the pH meter for any signs of corrosion or damage caused by the leaked battery. If you notice any significant damage, you may need to consult the manufacturer for repairs or replacement.
    6. Replace the battery: Once the battery compartment is clean and dry, insert a new battery of the correct type and polarity as recommended by the manufacturer.
    7. Test the pH meter: After replacing the battery, test the pH meter to ensure that it is functioning correctly. Calibrate it according to the manufacturer's instructions if necessary.
    8. Prevent future leaks: To prevent future battery leaks, consider using high-quality batteries, removing the battery from the device if it will not be used for an extended period, and storing the pH meter in a cool, dry place.
