pH, short for “potential of hydrogen,” measures acidity or alkalinity. The pH scale ranges from 0 to 14, with 7 being neutral. Anything below 7 is acidic, and above 7 is alkaline.

For hot sauce creators, understanding pH is crucial, especially when fermenting chillies. We use the process of lactofermentation to ferment our chillies, and during fermentation, lactic acid increases acidity and lowers the pH.

This enhances safety and contributes to the savoury flavours we love in hot sauce. To delve deeper into the significance of acidity in hot sauces and ensure the safety of your creations, check out our comprehensive guide here.

pH Testing Strips vs Digital pH Testers: Choosing the Right pH Testing Method


You’ll encounter two standard methods when testing pH in hot sauce: pH testing strips and pH meters. While pH testing strips suffice for testing water or transparent liquids, they fall short for hot sauce applications. The accuracy of pH testing strips is questionable, and they struggle to provide the level of precision necessary for hot sauce making. Since hot sauces come in various vibrant colours, relying on pH meters is a more intelligent choice for accurate results.

Exploring the Best pH Testers: Finding Your Perfect Match

Calibrating your pH Tester

Calibrating your pH meter is an essential step to ensure accurate and reliable readings. I would recommend following the instructions you get with your pH meter, but here is a step-by-step guide on how to calibrate your pH meter:

  1. Gather the necessary materials: Before starting the calibration process, make sure you have the following items:
    pH meter
    pH calibration solutions (pH 4.00, pH 7.00, and pH 10.00)
    – Distilled or deionized water
    – Clean container or beaker
  2. Rinse the pH electrode: Rinse the electrode with distilled or deionized water to remove any residue or contaminants from previous use. Gently blot the electrode dry with a clean tissue or lint-free cloth.
  3. Prepare the calibration solutions: Pour a small amount of each pH calibration solution into separate clean containers or beakers. It is essential to use fresh calibration solutions that are not expired.
  4. Start with pH 7.00 calibration solution: Immerse the pH electrode into the pH 7.00 calibration solution. Ensure that the electrode is fully immersed, and the solution covers the bulb at the bottom. Allow the reading to stabilize, which may take a few seconds.
  5. Adjust the pH meter: Once the reading stabilizes, adjust the pH meter to read pH 7.00 by either turning the calibration knobs or using the calibration settings on the meter. Follow the manufacturer’s instructions for your specific pH meter model.
  6. Rinse the electrode: Remove the electrode from the pH 7.00 calibration solution and rinse it with distilled or deionized water. Blot it dry gently.
  7. Repeat the process for pH 4.00 and pH 10.00: Follow the same steps for the other calibration solutions (pH 4.00 and pH 10.00). Immerse the electrode in the respective solution, wait for the reading to stabilize, and calibrate the meter accordingly. Rinse the electrode with distilled or deionized water after each calibration.
  8. Check the slope and offset: Some pH meters allow you to check the slope and offset values after calibration. The values should be within an acceptable range specified by the manufacturer. If not, consult the manual or contact the manufacturer for troubleshooting.
  9. Store the electrode: Once the calibration is complete, store the pH electrode properly according to the manufacturer’s instructions. Proper storage will help maintain the electrode’s performance and prolong its lifespan.

Remember, regular calibration is essential to maintain the accuracy of your pH meter. It is recommended to calibrate before each use or at least once a week, depending on the frequency of use and manufacturer’s instructions.

  3. Use calibration solutions
    Regular calibration is essential for accurate pH measurements. Have both a 7.0pH and a 4.0pH calibration solution on hand for a two-point calibration process. Follow the manufacturer’s instructions for calibration.
  4. Store properly
    When not in use, store the pH meter in a clean and dry environment. Some meters may come with a protective case or cover that can be used for storage. Ensure that the storage area is away from excessive heat, moisture, and direct sunlight.
  5. Avoid extreme temperatures
    pH meters are sensitive to extreme temperatures. Do not expose them to extreme cold or heat, as it can affect their accuracy and performance.
  6. Handle with care
    pH meters are delicate instruments, so handle them carefully. Avoid dropping or mishandling the device to prevent damage to the electrode and other components.

  1. Hi Chilli Champ,
    Commenting here as there is no article about your ferminator.
    You got small fan for hot air distribution inside fridge. Do you mix only internal air or have fresh air input.
    Explain please.

    This will help me in projects I’m in – edible mushroom cultivation, which might be also interesting for you.
    Fresh air circulation and proper humidity is crucial for species like shitake. Oyster mushrooms are less sensitive. But your fridge fermintor idea would work great for both I think.

    1. I am pretty sure I mentioned in the video, the fan is not for bringing external air in. It only turns on when the heating is on. It is there so that the heat distributes better inside the Ferminator, so there aren’t hot and cold spots.

  2. Hi Chillichump, thanks for sharing this.
    I have just ordered the same Apera PH20 device you use, and noticed the box doesn’t come with a storage solution. Is it essential to purchase this separately, or does this particular device not really need one?


    1. Hey Jim, I would recommend getting some storage solution. This is the one I use:
      While you could get away with using a few drops of tap water…I would rather ensure the longevity and accuracy of it by using the proper stuff.
