pH-метр для ґрунту та харчових продуктів LUTRON PH-220S : огляд, як калібрувати, як міряти pH грунту

The device is positioned by the manufacturer as a pH meter for the soil, but due to the presence of a universal "sharp" pH electrode of the penetrating type, it can be used to measure the pH of food (eg pH of cheese). The video shows what comes with the pH meter, how to properly calibrate it and how to measure the pH (acidity) of the soil. Link to pH meter: https://simvolt.ua/ph-metr-z-gostrim-...
