ITEM NAME:Ph Test Strips 1-14 in dicator Paper Lab Litmus Test 80 in 1 Kit for Water B2N2 Ph Test Strips 1-14 in dicator Paper Lab Litmus Test 80 in 1 Kit for Water B2N2 Testing Range: 1-14 Full Range; Size: 55mmx9mm / 2 inch x0.35 inch (L * W); pH Color Chart Intervals: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14,Widely applied to industrial chemical testing, science education, lab use, drinking water, swimming pool, spa, aquarium, hydroponics and classroom analytical chemistry. This paper does not apply to buffer solutions and very weak acid-base solution concentration lower than 0.01%.NOTE: Please note that solutions with a pH of 5.5 will result in a yellow colored test strip that resembles the color of the dry strip. Store in a cool, dry place away from sunlight. Instructions: 1. Take one strip and dip it into the solution you would like to measure. The color of your strip will change immediately.2. Quickly match this color against the color chart on the inside of package to obtain the pH in 15 seconds. Do not wait or let the strip dry!3. The number next to the color on the chart is your pH. The pH scale ranges from 1 (very acidic) to 14 (very basic), 7 is neutral. Instruction:1.Simply press the testing strip to the object or liquid you are testing. Half second later, take out the paper and using the color chart included, compare the color change of the paper to find out the acidity level of your testing subject.2.Can not indicate the Acid or alkali solution when its density was lower than 0.01%. 3.Keep dry for the rest paper. There is a strong correlation between the pH of the body's internal environment and pH paper help you to maintain good healthy body by testing many usual everyday substances, including moisturized soap, lemon juice, milk, liquid detergent, moisturized soil, saliva, urine, sweat...etc Common Uses of pH : Acid Rain, pH = 4.3 - 5.6 Based Glass Cleaner, pH = 10 Battery Acid, pH = 1 Beer, pH = 4.5 Bleach, pH = 12.6 Drain Cleaner, pH = 14 Dr.Keep dry for the rest paper. Simply press the testing strip to the object or liquid you are testing. Half second later, take out the paper and using the color chart included, compare the color change of the paper to find out the acidity level of your testing subject.2.
