Pouzdana pH mjerenja neophodna su za gotovo svaki proces ili industriju, od tla do otpadnih voda. Mjerenje pH ima klju\u010dnu ulogu u odre\u0111ivanju kvalitete vode, tla i jo\u0161 mnogo toga.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Postupci kalibracije pH metra mijenjaju se ovisno o tome koji se mjera\u010d koristi. Kako biste najbolje razumjeli svoj specifi\u010dni mjera\u010d, va\u017eno je pro\u010ditati priru\u010dnik kada dobijete svoj pH mjera\u010d.<\/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

Prilikom kalibracije pH metra va\u017eno je koristiti odgovaraju\u0107e pufere. Na primjer, ako \u017eelite izmjeriti ne\u0161to s pH 9, a kalibrirate svoj pH metar samo na pH 7, mo\u017eda ne\u0107ete dobiti to\u010dno mjerenje. To je zato \u0161to su pH mjerenja najto\u010dnija kada kalibracijske to\u010dke obuhva\u0107aju mjerenje. Tako\u0111er biste trebali provjeriti datum isteka pufera i koliko dugo je pufer otvoren. Neki puferi, kao \u0161to je pufer pH 10, istje\u010du mnogo prije 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 utjecaj na stanje va\u0161e elektrode. Hanna Instruments preporu\u010duje da pomak ne prelazi \u00b130mV i da postotak nagiba bude izme\u0111u 85-105%.<\/p>\n

    Ako imate lo\u0161 pomak, to mo\u017ee zna\u010diti da imate ili za\u010depljen spoj ili da je sonda potrebno \u010di\u0161\u0107enje. Ako se to dogodi, poku\u0161ajte natopiti sondu u otopinu za \u010di\u0161\u0107enje i ponovite postupak provjere pomaka. Ako je va\u0161 nagib lo\u0161, to mo\u017ee zna\u010diti da ste koristili istekle ili kontaminirane pufere. Ako je to slu\u010daj, osigurajte da se koriste svje\u017ei puferi.
