Features:1.Simple Operation: Remove a small test strip, touch the liquid being tested, and compare the test results to a standard color on the card after a few seconds.
2.pH Measurement Range: The pH level test paper has a full pH range, measuring pH from 0 to 14.
3.pH Color Card Spacing: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14. The pH level test paper is easy to read.
4.Convenient to Use: The pH test paper has a roll design, making it lightweight and compact, easy to use and carry.
5. 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.
Specifications:Item Type: pH Test Paper
Material: Paper
Weight: Approx.19g / 0.7 oz
Use the range: as long as it is an aqueous solution, it can be measured.
1.Testing amniotic fluid: (The average vaginal secretion is acidic, and amniotic fluid is alkaline; the acid alkalinity is 7 or higher.) Use sterilized cotton to select an acidic or alkaline fluid.
2.Testing cosmetics: (Because skin is slightly acidic, the acidity of cosmetics is approximately 6. If there is no skin damage (the test strip is not discolored, the pH is 6, and there is no change), use a color block, then a color chart, find the closest color, and plot the alkalinity block.
3.ALKALINITY OF MAY: Closest color, to draw the alkalinity,
4.
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 of the color card is 7. 7 indicates a base; the higher the value of 7, the lower the acidity.
