Specifications: Color: Range 1 to 14 color chart in each pack Paper Size: 50mm x 9mm (L x W) Pack size: 66 x 45x 4mm(L x W x H) Weight: 8g each pack litmus ph test strips HOW TO READ ? Make sure your strips test the range you need. The pH scale covers a range of 14 numbers, where 7 is neutral. Lower numbers are more acidic, while higher numbers are more alkaline. Some strips only test a portion of that spectrum, so make sure the strips you buy cover the pH levels you want to test for. Some test strips only need to be left in the test liquid for about a second, while others need about 20 seconds to produce a reading. Be sure to read the instructions to ensure that your reading will be accurate Dip one end of the test strip in the substance you want to test. You don’t need to submerge the whole strip in the test substance. Hold the strip at one end and dip the other end in the liquid, then remove it after the appropriate length of time You can use pH strips to test the pH level of any liquid. Compare the color of the strip to the chart provided. Your pH strips should come with a pH color chart. When your test strip has finished reacting, hold it up to the chart and compare the color of the strip to the color chart. When you find the number associated with the color on the strip, you’ll have your pH reading.[4] Acids are represented by warm colors, such as red and orange, while alkalines are associated with cooler colors, like blue and green. Test your tap water to make sure it’s acid neutral. Water is neutral, meaning it should have a pH balance of 7. Most drinking water falls in the range of 6.5-8.5. Test your drinking water to see if it falls within this range. If it isn't, there may be a contaminant in your water supply PH strips for science education PH test paper can also be used as a science education tool for children If you’re interested in testing the alkalinity or acidity of a liquid, you can use pH strips to help you determine the pH level. If you’ve never used a pH strip, though, it might look like just a plain strip of paper Keep your swimming pool balanced by testing the pH levels should stay at a pH balance of between 7.4 and 7.6. Add a product made with soda ash if the pool is below 7.4 and muriatic acid if it’s above 7.6 Test the pH levels in your aquarium if you have one The pH balance in your aquarium is critical to keeping your fish healthy. Since the pH levels of natural waters vary, it makes sense that different fish would have different pH requirements. Make sure you know the best pH range for your fish and test your water to make sure it falls within that range Measure the pH of your saliva to test your oral health. The average pH of saliva is around 6.7, but a normal range is anywhere from 6.2-7.6. If you measure your saliva and it is drastically different, your teeth are at a higher risk for cavities or gingivitis This pH test paper can be used in university laboratories, chemical plants, and scientific research institutions Multiple Uses: Testing the pH of body saliva and urine to check your healthCheck your pet dog's body acid-baseTesting your hydroponic plant growth environmentDo some science experiments with your children about acids and bases to rich scientific knowledgeAlso apply to testing household items, drinking water, swimming pools, fish tank, aquariums,food, etc.

Packet Size 45mm x 7mm (L x W), Package Include 4 packets x 80 strips (320 strips), Measurement range from pH 1 to pH 14.

Achieving cost-effectiveness and efficiency - Simply tear off a small piece of pH test paper and place it on a clean tabletop, then carefully drop a small amount of sample solution onto the center of the pH test paper to promptly observe an immediate color change.

Each packet of pH strips is accompanied by a unique standard colorimetric chart that indicates the corresponding pH value for each color. By simply matching the test results to the standard colorimetric chart, one can easily determine the correct pH value.

Do not immerse the pH test strip directly into the solution, otherwise the test results will not be trusted.

pH test paper is extensively utilized in various production fields such as chemical, food, aquaculture, and agriculture. For instance, pH testing is necessary during the manufacturing process of fertilizers, soaps, cosmetics, and condiments. Additionally, monitoring soil and water pH levels are crucial when planting trees or raising fish. In daily life scenarios like measuring urine or saliva pH levels can help us understand our physical condition.
