Confirm neutrality of air conditioning cleaning waste liquid

It helps waste liquid treatment. Do not discard as diluted with plenty of water as it is.

It is also compact and very easy to use, even cut length freely. I'd like to purchase this price because it will continue in the future.
Use when you want to know ph of detergent etc.

Ease of handling is good. I wrapped the test paper with aluminum foil, but I think that it was good if there was ingenuity to dry the whole case. Also, it is easy to cut freely if there is a perforation like toilet paper when cutting.

Because the interval between PH is narrow, it is easy to obtain accurate values. I also want to use it next time.
When confirming whether it is acidic or alkaline
On 2016-08-03 22:12:59
I bought it to find out how much ph value the purchased rust removing solution is. I wish I knew about the numerical value, so I could use it without problems with my own way of use.

I think that it is quite good feeling.
When soil PH is confirmed
On 2016-06-20 09:42:15
Although I bought a PH meter several times, when the period not in use becomes long, the system falls and it can not be calibrated. Although the PH test paper is disposable, it can be used with peace of mind once purchased once a year.

I wish I could have perforated etc if I wanted greed.

Pull out ⇒ Hold the side (Pull the tape does not come out) ⇒ Cut at the jagged blade ⇒ The next drawer remaining about 2 cm. If this withdrawal fee is available next time, it is very convenient to draw out easily. Without a withdrawal fee it is very troublesome to open the lid and set the tape in the slit ....

I am satisfied very much for the price, Although it is a difficult point to not know much about the comma or less, since my own way of using it is zakkuri, it is good
PH measurement of reagent pH adjustment
On 2016-03-16 19:03:53
Since pH measurement in a wide area is possible, it is convenient to determine a standard. Because it is a roll type, it can be economically used. It is difficult to cut the test paper in the case, and I use scissors. I think it will be better if this improvement is made. In the summer, the sun is hit, it is kept in a place where it gets hot and has experienced decolorization. It is a point that needs attention. I think whether it is convenient that the color code attached to the case is on both sides. Cut it off, put the case, immersed it in reagent, and tried to see the pH at that time, the case was surprisingly opposite, and I felt somewhat inconvenient.

Since I purchased it as a spare, I have not used it, but since the same type of thing was used for 40 years in job quality control, it is a very convenient item.
Measurement of pH of PH and soil of fermentation solution of water · EM bacteria

Relatively easy to use, it is accurate. It is accurate even when compared with the product measured with liquid.

It is convenient because it is a roll type. I ordered and arrived the next day.

A good point ... with a blade to cut. If you cut with this blade it will cut out about 2 cm in length. It is very convenient because you can take out the part of 2 cm when pulling it out next, and you can pull it out immediately. There is no convenient blade in other company's products, so it is hard to draw out. Bad point ... pH 12 to 14 seem to be the same color and can not be identified. Although it is a rough confirmation, there is no practical problem.
