Suitable pH values for different plants differ from each other. The pH value of foods, such as fruit, meat, and vegetable are also an important indicator of their quality. For example, by measuring the pH value of meat, we can determine whether the meat we bought is fresh or not.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eThe pH probe of this kit is attached with a spear-like protection shield made of stainless steel with a sharp tip.
