Background: There are usually two ways of determining pH value, which have been used for years: one is to use pH test strips, the other is to use pH testers. The former is of lower precision, greater error and unreliable result, and especially incapable in testing weak buffer solutions and acid or alkaline solutions which are of excessively low concentration. Although the latter is more accurate, the apparatus involved are expensive, with complicated and demanding operation, making testing process inconvenient. The researchers of Ningbo Thaile Chemical Technology Co.,Ltd have after years of in-depth study , successfully developed a new pH test kit, under the brand of "Thaile". This kit, by overcoming the drawbacks of the above 2 traditional methods, can achieve better and reliable results with greatly simplified operation and lowered the testing costs.
Principle:Use a specific high-sensitivity reagents, show a variety of colors under different pH.
Purpose: Capable of testing any colorless acid or alkaline solutions which in pH 4-10. Usually it used in on-site rapid testing of living water, aquaculture, environmental protection, industrial water etc.
Features: Accurate, easy to handle, inexpensive, easy to carry.
Operation:
1.Wash the colorimetric tube twice with water sample. Then,measure and take certain amount of water using the colorimetric tube. Adjust the level to the graduation mark of 15 ml using a plastic dropper.
2.Drip 1-2 drops of Reagent into the colorimetric tube and shake up.
3.Read the pH according to the color change of the solution, against the color chart.
Notes:
1. If the water sample appear turbid, filter the sample, or stand the sample until it is clear, then take sample from the upper part, before testing.
2. Try to compare the colors in bright light.
3. The plastic dropper is used only for adjusting the water volume when measuring and taking the water, not for dripping the reagent. The above mentioned “drop” of reagent represent the drop squeezed from the reagent bottle.
4.Inflammable product, keep away from fire. In case of body contacts, rinse with water.
5.After use,please tighten the cap to avoid ineffectiveness.
6.This is test reagent ,not food or drink, is toxic and harmful if swallowed. Keep out of reach of children.
7.Handle with care, it may cause staining.
8.Store in a cool and shady place.
Liability: The manufacturer and its authorized reagents are free from any liabilities due to taking by accident of children and misunderstanding or misuse of the users. If result is suspected based on this test, consult an analytical testing laboratory and take the necessary precautions.
