Specification Brand : MXITA BulletPoint1 : 【Easy to use】It only takes a second to know the result. Take out the pH test paper, dip a small amount of the substance to be tested on the paper and watch the colour change. Compare the colour classification on the colorimetric plate to know the pH value. BulletPoint2 : 【Caveat】The colour change of the test paper must match the pH scale colorimetric card within about 15 seconds, after which the value is prone to deviation. BulletPoint3 : 【Packaging quantity】Each book of pH test strips has 80 strips to meet your usage needs. BulletPoint4 : 【Wide range of uses】pH test strips can be used to test many substances such as water, saliva, urine, sweat, beverages, skin care products, vegetables, fruits, and soil. BulletPoint5 : 【Precautions for use and storage】 Do not put the test paper directly into the solution, but use a dropper or a small stick to take a drop of solution onto the test paper. Store the paper in a dry place away from light.

Firstly, let's understand the working principle of PH test strips. After the electrode sheet in the test paper comes into contact with the liquid, the acidic and alkaline substances in the liquid will have an electrochemical reaction with the electrode sheet. By detecting the potential difference generated on the electrode sheet, we can know the acidity or alkalinity of the liquid. Simply put, PH test paper is like an acidity meter, which can help us quickly and accurately understand the acidity and alkalinity of the liquid. So, how to use PH test paper correctly? We simply divide it into the following three steps for you: Step 1: Start by removing a strip of test paper to make sure there is no damage. Step 2: Take an appropriate amount of liquid drops on the end of the test paper, try to liquid contact evenly. Step 3: Wait for the result to be displayed and compare it with the colour of the colorimetric card to understand the acidity or alkalinity of the liquid. It is important to note the following when using PH test strips: 1. The amount of liquid sample should be moderate, too much or too little will affect the test result. 2. When testing, the test paper should be in full contact with the liquid to avoid foam and bubbles affecting the results. 3. The test paper should be properly stored after use in a dry and cool place to avoid moisture.
