Ukuze uqinisekise ukulinganiswa kwe-pH okunembile emapayipini nokuvimbela amaphutha edatha abangelwa amabhamuza omoya esitokisini sokulinganisa, sicela ulandele umdwebo wokufaka ngokuqinile.
Amanothi:
(1) I-electrode kufanele ifakwe emgqeni odlulayo wepayipi eliyinhloko. I-valve kufanele ifakwe engxenyeni engaphambili ukulawula izinga lokugeleza. Ukugeleza kufanele kube phansi ngangokunokwenzeka; ngokuvamile, ukuconsa okuzinzile okuvela endaweni yokukhipha amanzi kwanele. I-electrode kumele ifakwe ngokuqondile futhi ifakwe emanzini agelezayo. Indawo yokukhipha amanzi kufanele ibe phezulu kunokungena kwamanzi ukuqinisekisa ukuthi i-electrode igcwele ngokuphelele esixazululweni.
(2) I-electrode kufanele ilinganiswe ngaphambi kokufakwa.
(3) Isignali yokulinganisa iyisignali kagesi ebuthakathaka. Ikhebula lesignali kufanele lihanjiswe ngokwehlukana futhi akumele lixhunywe kusixhumi sekhebula esifanayo noma ibhulokhi yesiphelo njengezintambo zikagesi noma izintambo zokulawula ukuze kugwenywe ukuphazamiseka noma ukulimala kweyunithi yokulinganisa.
(4) Uma ikhebula lokulinganisa lidinga ukwelulwa, sicela uxhumane nomkhiqizi noma ucacise ngaphambi kokulethwa (ubude obuzenzakalelayo buyi-10m).
Ukusebenza Okuyinhloko Kwamamitha e-pH
Izici Eziyinhloko:
Ukulinganisa okungu-1.pH/ORP, ukulawula umkhawulo ophezulu/ophansi, umkhiqizo wamanje, kanye nokuxhumana kwedijithali
2. Isinxephezelo sokushisa esenziwe ngesandla noma esizenzakalelayo
