What I can see with my eyes has a sense of satisfaction, I think it is good.
Inspection before and after wastewater treatment
On 2018-03-09 14:06:29
The upper cover does not fit and it can not be rotated, it fills the test paper and it is not fitted an extra. The test paper itself was also packaged with the border bent. Supporting people corresponded quickly, so it was good as we did the return procedure on the same day.
Used to check water quality of soft water system

I can not say anything because I have not used so many of these hands, but I can use it normally. (Bitter smile)

Because this product has a rather wide measurement range, it is recommended to use it in conjunction with a finer range of test paper for detailed analysis.

Cospa is good. It was affordable and it was easy to adjust the size.
PH measurement of hypo-water

When unpacking a new item, I will use it from the incision but I am dissatisfied that it is hard to pick up paper more than I thought. I hope it improves.

Convenient to conveniently measure pH.
Durability is also sufficient.
For purpose, when you measure the pH (8 to 9) in the vicinity of the weak alkali, you are strongly in a different grade, so you are satisfied with the institutional

It is aignment. If it says so, as the test paper ink after inspection drips as water droplets, things that you do not want to transfer color are caution.

It is troublesome to take out and peel off from the box that the monotary seal is pasted, so I want you somehow.
Liquid PH check
On 2017-10-02 16:08:31
It is very convenient to measure rough PH degree in a short time. I think that it is a good product without discoloring even if it is kept for a long time.

I am very saved because it is a bargain. I will continue to buy it.
PH check of oxidation potential water
On 2017-04-29 15:29:14
You can go easy. Because I had you buy it before, I understood that there was a search for HP and asked for it
On 2017-04-05 23:39:13
I am happy that it is price-saving, I used it very conveniently.
Confirm neutrality of air conditioning cleaning waste liquid
On 2016-11-27 07:38:37
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.
When measuring the liquid pH
On 2016-07-25 15:57:56
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.
