Test ph adjustment
On 2016-08-18 10:22:07
The expiration date was not over but the test paper did not discolor. While confirming with the owning PH measuring instrument, we confirmed discoloration, but we could hardly see anything that discolored. It seems that there was obviously already discolored inside, and management of the item was bad. I got an inquiry and received a new item on exchange, but the quality was the same as what I came for the first time. I made an inquiry again and confirmed that it was shipping from the stock of monotail. Direct delivery from the manufacturer finally reached a decent item. There is a doubt in product management of this hand.
PH control of alkaline electrolyzed water

Results of almost no discoloration (less than 7.5) for specimens of about 10.4 for both Handy pH meter and 10-12 pH test paper. If it is an error of about 0.5, it was a level without problems, but it can not be used with this. Is there any other influence? Also, not limited to this product, the enlarged chart of the color chart is not displayed on the pH test paper in general, so it is difficult to select the product. Please make improvements by all means.

Because it contains only one color chart, I got in trouble as I got wet with water and I could not understand the color. Whether the product has passed the time, the color can not be determined ((+ _ +))
