liquids such as organic solvents, oils, adhesives, strong acids (pH 0 to pH 2), strong alkalis (pH 12 to pH 14) and surface-active agents. The pH reading may become unstable when measuring pure water. If the pH standard solution contacts the skin (hand), immediately wash the contaminated skin with running water. - Page 4 Cautions before use Check that the instrument has not been damaged during transport. If damage is found, contact the store where you purchased the instrument or our service network. When the pH of food or drink is to be measured, take a sample (sufficient quantity so that the sensor tip can be immersed at least 3 cm in the sample) in a separate container for measurement.
