Confirmation of acidity of highly pure acidic solution (pH 3.8 to 5.4)
On 2018-07-26 09:14:12
The pH 3.8 ~ 5.4 was used in the pH tester to check the acidity of the solution that can not be measured.
There are two places to react in pH 3.8 to 5.4, but the one that comes out darker becomes more dense than the color sample.
Also, there are color irregularities, the surroundings get dense. There is a color sample in the middle of those with thin color.
Because it is inexpensive, it is convenient because it can be used freely a lot when coarsely matched.
The final confirmation was used together with MN (MACHEREY - NAGEL) pH test paper (pH - Fix) pH 3.6 - 6.1.

cheap. Handling is a disadvantage that the stick is easy to fall in the case.

It is easier to use if you improve the product cover easier to remove "pretty hard to remove". I think that PH measurement can be measured by roughly changing color.
Simple measurement in chemical experiment

For complex electrodes, cleaning operation per use is quite difficult, so we use it for simple measurement. I feel that accuracy is good as well. Since it is in a case, it is attractive to always put it in a bag and measure it anywhere.

It is cheap and easy to use.

It is convenient when you are hitting a large number of samples at overseas sites where there are few clean water etc. for washing
