Inget satu hal utk pH digital merk apapun, rendam indikatornya dgn buffer solution pH7.0, caranya bisa buat sendiri (coba lihat artikel water chemistry saya) atau beli buffer solution 7.0 (tapi mahal) kalo ga direndam, indikator akan cepat rusak, sekaligus buffer solution itu bisa buat kalibrasi pH tester anda.

Di mana ya bisa beli buffer solution pH7.0? Dan harganya kira2 berapa? Soalnya standart solution saya (dari ph tester merk Resun) pecah dan isinya tumpah semua.

Indikator ph tester rusak itu seperti apa? Apa bisa diperbaiki?

Terima kasih
