Prilikom kalibracije pH metra va\u017eno je da se koriste odgovarajuc\u0301i puferi. Na primer, ako \u017eelite da merite ne\u0161to sa pH od 9 i kalibri\u0161ete samo pH metar na pH 7, mo\u017eda nec\u0301ete dobiti ta\u010dno merenje. To je zato \u0161to su pH merenja najta\u010dnija kada ta\u010dke kalibracije obuhvataju merenje. Tako\u0111e bi trebalo da proverite datum isteka va\u0161ih bafera i koliko dugo je bafer bio otvoren. Neki puferi, poput pufera pH 10, isti\u010du mnogo ranije od datuma isteka kada se otvore.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    Va\u0161 nagib i pomak imaju zna\u010dajan uticaj na stanje va\u0161e elektrode. Hanna Instruments preporu\u010duje da pomak ne prelazi \u00b130mV i da je procenat nagiba izme\u0111u 85-105%.<\/p>\n

    Ako imate lo\u0161 pomak, to mo\u017ee zna\u010diti da ili imate za\u010depljen spoj ili da je potrebno \u010di\u0161c\u0301enje sonde. Ako se to dogodi, poku\u0161ajte da natopite sondu u rastvor za \u010di\u0161c\u0301enje i ponovite postupak provere pomeranja. Ako je va\u0161 nagib lo\u0161, to mo\u017ee zna\u010diti da ste koristili istekli ili kontaminirani puferi. Ako je to slu\u010daj, uverite se da se koriste novi puferi.
