Return Policy
For hygiene reasons, this product is non-returnable once used. The electrode may become damaged and unusable for another customer. We recommend ensuring it meets your expectations before use. If you have any questions, we are at your service.
How to Measure the pH of Creams Using the pH Meter
1. Preparing the Meter
- Electrode cleaning: Rinse the electrode with distilled water before each use to avoid cross-contamination.
- Calibration: Use standard buffer solutions (e.g. pH 4.01 and pH 7.01) to calibrate the device. Regular calibration is essential for accuracy.
2. Sample Preparation
- Light creams or gels: Can be measured directly by immersing the electrode into the sample.
- Thick creams or emulsions: Prepare a 10% dilution with distilled water. For example, mix 1 part cream with 9 parts water.
3. Measuring pH
- Electrode immersion: Submerge the electrode in the sample or prepared dilution.
- Stable reading: Wait until the value stabilises on the screen before recording.
4. pH Adjustment (if necessary)
- To increase pH (make more alkaline): Gradually add a diluted alkaline solution, such as sodium hydroxide, and mix thoroughly.
- To decrease pH (make more acidic): Gradually add a diluted acidic solution, such as citric acid, and mix thoroughly.
Additional Tips:
- Sample temperature: Ensure the sample is at room temperature (approx. 25 °C) for accurate readings.
- Electrode maintenance: After each use, rinse with distilled water and store as recommended by the manufacturer to extend its lifespan.
