roll of pH test strips, acid/alkaline indicator, test paper roll for water, urine, saliva, soil, sunflower, precise measuring tool

Easy to use: Remove a small test strip, touch the liquid to be tested, and after a few seconds, compare the test results with the standard color on the card. If there is no reaction, you can leave it for longer. High accuracy and wide application: Good quality, fast and accurate results in seconds. As long as it is an aqueous solution, it can be measured. pH measurement range: The pH level test paper has a full pH range, measuring pH from 0 to 14. The color changes of the test strips correspond to the pH scale color chart in seconds. Multiple applications: The universal pH paper is a good teaching material for schools and laboratories, and can also be used for fish testing, hydroponics, aquariums, industrial testing, agricultural testing, etc. Convenient to use: The pH test paper has a roll design, is lightweight and compact, easy to use and carry. The color changes of the test strips should be aligned with the pH scale within approximately 15 seconds. The pH discoloration range varies; compare the color chart accordingly. Product Description Specification: Item Type: pH Test Paper Material: Paper Weight: Approx. 19g/0.7 oz Usage Range: As long as it is an aqueous solution, it can be measured. 1. Testing Amniotic Fluid: (The average person's vaginal secretions are acidic, and amniotic fluid is alkaline, with an acid/alkalinity of 7 or higher.) Use a sterile cotton ball to collect vaginal secretions, apply it to the color block, then to the color chart. Find the closest color, and draw a color from the alkaline/sour scale. If the color is zero or 6 or lower, it is not amniotic fluid; 7 or more colors indicate amniotic fluid. 2. Testing cosmetics: Principle (because skin is slightly acidic, so the cosmetic pH is approximately 6 if there is no skin damage (the test strip is not discolored, the pH is 6, no change indicates a good cosmetic). On the color block, then the color chart, find the closest color to determine the alkalinity. 3. Meat alkalinity: Saliva is applied to the colored block, then to the color chart, find the closest color to determine the alkalinity. 4. Truck alkalinity: Urine is applied to the color block, then to the color chart, find the closest color to determine the alkalinity. How to use: The test sample is prepared separately; place the color block directly into the liquid; remove, remove excess moisture, then the pH value on the color chart is 7. The higher the pH, the more alkaline the base; the higher the pH, the more acidic the base. Smaller, stronger. Packing list: 1 roll x pH test paper, 1 box
