1. Product name: PH test paper
2. Packing method: Sealed with plastic film, each pack / 80 sheets with standard color card
3. Effective range: 1-14
4. Method of use: drop or smear the liquid to be tested on the PH test paper, it can be reflected and displayed almost without waiting, and then compared with the attached standard color chart to get the PH value.
5. How to use pH test paper 1-14
6. Step 1: Open the strip-shaped piece of paper exposed by the test bag, the paper sheet is pH test paper, and there are 1-14 color cards on the surface of the box.
7. Step 2: Remove the test strip and place it flat on a dry glass or plastic sheet (Note: the glass or plastic sheet must be dry and clean);
8. Step 3: Use a glass rod or pipette to take the test solution and drop it on one end of the test paper;
9. Step 4: After one second, the solution part of the test paper and the test paper produce a color change. At this time, compare with the standard color card and read the pH value. In the test, the lower the pH value, the stronger the acidity of the solution. When the pH value is 7, the solution is neutral, the greater the pH value, the stronger the solution's alkalinity;
10. Cosmetic test: Because the pH of the skin is about 6, it is a weak acid, so the pH of the cosmetic is about 6 so that it does not damage the skin pH balance, so the pH value is close to 6 without harming the skin. 6, ph is very good between 5 and 7), Cosmetics are applied on the test strip, and then the closest color is found by comparing the color chart, and the pH is obtained.
11. Test for amniotic fluid: The urine and vaginal discharge of most people are acidic, while the amniotic fluid is alkaline. (Take a vaginal secretion with a sterile cotton swab, apply it on a test paper, and compare the color chart to find the closest color, pH 7 The above indicates amniotic fluid; if it does not change color, it means that it is not amniotic fluid.)
12. Measure the pH of the human body, the saliva sticks to the test paper, compare the color card, find the closest color, and get the pH of the human body
13. Test urine pH: Urine stained on the test paper, urine stained on the test paper, compare the color card, find the closest color, and get the pH of the human body
14. Check the acidity and alkalinity of the gas: first wet the test paper with distilled water, stick it to one end of the glass rod, and then send it to the mouth of the container containing the gas to be measured, observe the color change and judge the nature of the gas. (The test paper cannot touch the wall of the device)
15. Used for pH testing of soils; Some plants require acidic or weakly acidic soils. It is necessary to measure the acidity of new soils or substrates that have been used for a long time!
16. Measurement method of soil pH (PH value): When measuring the pH value of the substrate, you can sample a little soil, put it in the bottom of the bowl, then add 4-6 drops of distilled water, and stir well. After it is still and clarified, immerse a part of the PH test paper in the clear solution, and then the test paper will change color. The pH value can be directly obtained by comparing the discolored test paper with the PH standard color chart.

1. 产品名称：PH试纸 PH广泛试纸
2. 包装方式：塑料薄膜密封，每包/80张 附标准色卡
3. 有效量程：1-14
4. 使用方法：将所需检测的液体滴到或沾抹在PH试纸，几乎无需等待即可反映并显现，然后与附带的标准色卡比较，得出PH值。
5. pH试纸1-14的使用方法
6. 步骤1：打开试纸的包装袋露出的条状纸片，纸片为pH试纸，盒子表面有1-14种色卡，此色卡为pH标准色卡;
7. 步骤2：取出试纸片，平放于干燥的玻璃片或塑料片上面(注明：玻璃片或塑料片必须是干燥清洁的);
8. 步骤3：用玻璃棒或吸管取被测溶液滴于试纸的一端;
9. 步骤4：一秒钟后试纸的溶液部位与试纸产生色的变化，此时与标准色卡对比，读出pH值，在检测中，pH值越小，则说明溶液的酸性越强，pH值为7时，溶液呈中性，pH值越大，则溶液的碱性越强;
10. 测化妆品：因为皮肤的酸碱度是6左右属弱酸，所以化妆品的酸碱度是6左右才不会破坏皮肤酸碱平衡，所以ph值接近6才对皮肤没有伤（试纸条不变色ph值就是6，ph在5至7之间都是很好的），【化妆品涂于试纸条上，然后对照比色卡找到最接近的颜色，得出酸碱度
11. 测羊水：一般人的尿液阴道分泌物是酸性的，而羊水是碱性的，【用消毒棉签取阴道分泌物，涂到试纸上然后对照比色卡，找到最接近的颜色，酸碱度7以上表示是羊水;如不变色或者6一下说明不是羊水。
12. 测人体酸碱度，唾液粘到试纸上，对比色卡，找到最接近的颜色，得出人体酸碱度
13. 测尿液酸碱度：尿液沾到试纸上，尿液沾到试纸上，对比色卡，找到最接近的颜色，得出人体酸碱度
14. 检验气体的酸碱度：先用蒸馏水把试纸润湿，粘在玻璃棒的一端，再送到盛有待测气体的容器口附近，观察颜色的变化，判断气体的性质。（试纸不能触及器壁）
15. 用于土壤的PH测试；有些植物的用土要求酸性或弱酸性，对于新土或使用很长时间的基质有必要进行酸度的测定!
16. 土壤酸碱度（ＰＨ值）的测定方法： 测定基质的PH值时，可先取样土少许，放入碗底，然后加入蒸馏水4-6滴，充分搅拌均匀，待其静止澄清后，将ＰＨ试纸一部分浸入清液中，试纸即变色，然后用变色的试纸与PH标准比色卡进行比较，即可直接得出PH值。
