A set of 80 litmus test strips for determining the pH level in liquids.

They are designed to determine pH in the range of 1-14 with a step of 1 pH unit. In this case, the error can fluctuate around "1" (unit) for concentrated solutions and reach 3 in the case of determining the pH of weakly concentrated solutions (water, soil extracts, etc.).

Measurement range: 1-14 pH (color scale on the package)

• 1-3 high acidity
• 4-6 acidic environment
• 7 neutral environment
• 8-11 alkaline environment
