Johnson Comparator Test Paper, 058.5, 9.0 to 13.0 pH, 7MM Width x 5 Mtrs Reel Length

Johnson Comparator Test Paper is a type of pH testing strip that is used to determine the acidity or basicity of a solution. It is suitable for use in a wide range of applications, including educational and laboratory settings. The paper is marked with a pH range of 9.0 to 14.0, which covers a wide range of acidity and basicity. The comparator test paper is designed to change color when it comes into contact with a solution within this pH range, and the color change can be compared to a color chart to determine the exact pH of the solution. The test paper is 7mm wide and comes on a reel that is 5 meters in length, providing a large number of strips for use. The 058.5 designation refers to the specific formulation of the comparator test paper, which has been designed for optimal accuracy and reliability.
