I think that the value is not accurate. It was initially displayed as PH 4 or less (weakly acidic) in the aquarium, and I thought that there was no problem with water quality. After purchasing the PH meter, I measured it, it was PH 7.5. When measured with tap water, which was correct, the litmus paper was PH.6.4 and the pH meter was PH 7.1. I think the PH meter is correct.

It is suitable for checking the pH of the region between neutral and the isoelectric point of the protein. The colorimetric range is divided into many, and it is easy to use.
