PHS-1701 feaveaipH mitao se fa'aaliga numeraPH mita, faʻatasi ai ma faʻaaliga numera LCD, lea e mafai ona faʻaaliaPHma tau le vevela i le taimi e tasi.O le meafaigaluega e faʻaoga i fale suʻesuʻe i aʻoga kolisi laiti, suʻesuʻega inisitituti, mataʻituina o le siosiomaga, alamanuia ma mining pisinisi ma isi matagaluega poʻo faʻataʻitaʻiga fanua e fuafua ai vaifofo vai 'PHfa'atatau ma fa'atatau (mV).Fa'aauupegaina i le eletise ORP, e mafai ona fuaina le tau ole ORP (oxidation-reduction potential);fa'aauupegaina i le ion electrode patino, e mafai ona fuaina le tau eletise eletise o le electrode.

O le a le pH?
O le PH o se fuataga o le gaioiga o le hydrogen ion i se vaifofo.Vai mama o lo'o i ai le paleni tutusa o ion hydrogen lelei (H +) ma
leagaion hydroxide (OH -) e leai se pH.
● O vaifofo e sili atu le maualuga o le hydrogen ions (H +) nai lo le vai mama e acidic ma e itiiti ifo i le 7 le pH.
● O vaifofo e sili atu le maualuga o ion hydroxide (OH -) nai lo le vai e fa'avae (alkaline) ma e sili atu le pH nai lo le 7.
Aisea e mataituina ai le pH o le vai?
