Feature
●Wide range of uses: There is a strong correlation between pH and pH in the human bodys internal environment. PH paper can help you maintain a healthy body clean, moist floor, saliva, urine, sweat, etc. by using many everyday substances such as wet soap, lemon juice, milk and liquids. Easy to use and carry.
●PH value detection: scale value from 1 to 14. 1-3 means extremely acidic substance, 4-6 means acidity, 7 means neutral, 8-11 means alkalinity, 12-14 means high alkalinity, The package includes 80 pH test strips with a paper size of approximately 45 mm x 7 mm (length x width) to meet your needs.
●High precision: pH Test Paper is made of high-quality materials to ensure high-precision measurement. The paper to be tested will produce color while conforming to the solution being tested. The color change of the test paper must meet the color scale of the pH scale within 15 seconds.
●How to use: Simply press the test strip on the object or liquid to be tested. Remove the paper after half a second and compare the color change of the paper to the supplied color card to determine the acidity of the test item. If the density is less than 0.01%, an acid or alkali solution cannot be displayed. Keep the remaining paper dry.

Description
About Test Strips
The Ph test paper is a type of paper that absorbs water well. The general Ph analysis test paper contains methyl red (ph4.2 (red) ~ 6.2 (yellow)) bromocresol green (ph3.6 (yellow) ~ 5.4 (green))) bromothymol blue (ph6.0 ~ (yellow) ~ 7.6 (blue ) The Appropriate Amount of These Mixed Acid Base Indicators May Reflect The Range Of Variation Of Ph 4.5 ~ 9.0.
Note:
The measurement standard for the Ph value is 1 to 14, the Ph value for the neutral solution is 7, the Ph value for the acidic solution is less than 7 and the Ph value for the alkaline solution is greater than 7. each The lower the pH value, the more acidic the solution and the higher the pH value, the greater the alkalinity.
Detection Method

|
|---|---|---|
Take a test paper |
Pour water into the disposable paper cup and place the test paper in the test for 2 seconds |
Take out the color in the comparison chart and find the ph value of the test |
Instruction:
- 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.
- Can not indicate the Acid or alkali solution when its density was lower than 0.01%.
- Keep dry for the rest paper.
