2pcs Alkaline Acidity Meter Test Paper Indicating PH Saliva Soil Litmus Accurate Measurement 1-14 PH 10m

Easy to use and use: take out a small test strip, touch the liquid to be tested, a few seconds later, compare the test results with the standard color on the carton, if there is no reaction, you can stay longer.High precision and wide application: good quality, fast and accurate results in seconds. As long as it is an aqueous solution, it can be measured.PH measuring range: The pH level test paper has a full pH range, measuring pH from 0 to 14.The color changes of the test strips should be matched to the pH scale color chart in seconds.Multiple applications: Universal pH paper is a good teaching materials for schools, laboratories, also can be used for detecting fish, hydroponics, aquariums, industrial testing, agricultural testing, etc.Convenient to use: The PH test paper has a coil design, lightweight and compact design, easy to use and carry. The color changes of the test strips should be matched to the pH scale color chart within approximately 15 seconds. The pH discoloration range is different, comparing the color card ratio.Product DescriptionSpecification:Item Type: PH Test PaperMaterial: PaperWeight: Approx. 19g/0.7ozUsage range: As long as it is an aqueous solution, it can be measured.1.Test amniotic fluid, principle (average person's vaginal secretion is acidic and amniotic fluid is alkaline, acidic alkalinity 7 or more) use sterilized cotton to collect vaginal secretions, apply it to the color block, then apply it to the color card, find the closest color, draw a sour alkaline, if the color without color or 6 or less is not amniotic fluid, 7 or more colors are amniotic fluid2. Test cosmetics, principle (because the skin of the skin is weakly acidic, so the cosmetic acid is about 6 or so if there is no damage to the skin (the test strip is not discolored, the pH is 6, no change is a good cosmetic) On the color block, then the color card, find the closest color, to draw the alkalinity3.Meat Alkalinity: Saliva is applied to the painted block, then on the color card, find the closest color, to draw the alkalinity,4. Truck Diadance: Urine is applied to the color block, then applied to the color card, to find the nearest color, to derive alkalinity. How to use: The test sample is prepared separately, directly put the color block into the liquid; Remove, remove extra moisture, then the PH value of the color card is 7. The basis, the higher the 7 alkaline, the smaller the acidity, the stronger.packing list:2 roll x PH Test Paper2 x Box
