Color : WiFi 6-in-1 pH Monitor CpsiaCautionaryStatement : no_warning_applicable Directions : How to Use: The test specimen is prepared separately, directly put the color block into the liquid; take out, take out the extra, then the value of the color card is <7 is acidic, =7 is neutral, >7 is The base, the higher the 7, the smaller, the stronger the acidity. Specification: Item Type: Test Paper Material: Paper Weight: Approx. 19g/0.7oz Use Range: As long as it is aqueous solution, it can be measured. 1. Test amniotic fluid, principle (the average person's vaginal secretion is acidic, and amniotic fluid is , alkalinity 7 or more) use cotton to pick vaginal secretions, apply it to the color block, then the color card, find the closest color , Draw a sour alkalin, if the color of no color or 6 or less is not amniotic fluid, 7 or more colors are amniotic fluid 2. Test cosmetics, principle (because the skin of the skin is weakly , so the cosmetic is about 6 or so if there is no damage to the skin (the test strip is not discolored, the is 6, no change is a good cosmetics) On the color block, then the color card, find the closest color, to draw the alkalinity 3. Meat alkalinity: Saliva is applied to the painted block, then the color card, find the closest color, to draw the alkalinity, 4. Truck diadance: Urine is applied to the color block, then the color card, find the closest color, to derive an alkalinity Package List: 1 Roll x Test Paper 1 x Box ExternallyAssignedProductIdentifier : 4713556901481 ExternallyAssignedProductIdentifier1 : 600316551229 ExternallyAssignedProductIdentifier2 : 0600316551229 FoldedSize : 7.2 x 1.5 x 1.5 inches IncludedComponents : pH Monitor set ItemName : Yewhick 6-in-1 pH Monitor Salt Temp S.G TDS EC Water Quality Tester, Continuous Monitor pH Tester PPM Meter for Aquariums, Hydroponics, Pools Tanks ItemPackageDimensions_Height : 2 inches ItemPackageDimensions_Length : 9 inches ItemPackageDimensions_Width : 6 inches ItemPackageQuantity : 1 ItemTypeKeyword : science-lab-ph-meters Manufacturer : Yewhick Material : Stainless Steel ModelNumber : YY-W9909-US NumberOfBoxes : 1 NumberOfItems : 1 NumberOfPieces : 1 PartNumber : YY-W9909-US PhRange : 0-14 ProductDescription : Yewhick 6-in-1 pH Monitor SALT Temp S.G TDS EC Water Quality Tester, Continuous Monitor pH Tester PPM Meter for Aquariums, Hydroponics, Pools Tanks ProductSiteLaunchDate : 2024-04-12T07:00:34.321Z RecommendedUsesForProduct1 : Urine Test RecommendedUsesForProduct2 : Saliva Test RecommendedUsesForProduct3 : Cosmetics RecommendedUsesForProduct4 : Water Test Size : approx. 183 x 37 x 37mm (7.2 x 1.5 x 1.5in) Style : Universal SupplierDeclaredDgHzRegulation : not_applicable SupplierDeclaredHasProductIdentifierExemption : 1 UnitCount : 1 UnspscCode : 41120000
