Because I thought that I wanted to do while checking PH, I thought that it was cheap in price but I bought it, but there is explanation that this is a rough judgment, even if it is plugged into the earth and measured roughly Then it is unsatisfactory and it is no longer used.
I usually played field (hobby) with a feeling of about, but I wanted to know ph quantitatively and purchased. As a result, it was biased to alkali by "excessive lime", so we immediately made remedial measures.

It was very easy to use, so I will try to use it easily and frequently.
