Xalalka qiyaasida pH ee caadiga ah
Qalabaynta soo noqnoqda ayaa ah dabeecadda ugu fiican ee lagu ilaalinayo saxnaanta cabbirka dareeraha pH/koontaroolaha, sababtoo ah cabbiriddu waxay ka dhigi kartaa akhrintaada mid sax ah oo la isku halayn karo. Dareemayaasha oo dhan waxay ku saleysan yihiin jiirada iyo dhimista ( isla'egta Nernst ). Si kastaba ha ahaatee, dhammaan dareemayaasha ayaa isbeddeli doona sida da'da. Xalka hagaajinta pH wuxuu sidoo kale kuu sheegi karaa haddii dareemehu dhaawacmo oo u baahan yahay in la beddelo.
Xalalka cabbiraadda pH ee caadiga ah waxay leeyihiin saxnaanta +/- 0.01 pH at 25°C (77°F). Sinomeasure waxay ku siin kartaa kaydiyeyaasha ugu caansan uguna badan ee la isticmaalo (4.00, 7.00, 10.00 iyo 4.00, 6.86, 9.18) kuwaas oo lagu rinjiyeeyay midabyo kala duwan si ay si fudud u garan karaan markaad mashquul ku tahay shaqada.
Sinomeasure heerka cabbirka pH wuxuu ku habboon yahay ku dhawaad codsi kasta iyo inta badan aaladaha cabbira pH. Haddii aad isticmaalayso noocyada kala duwan ee kontaroolayaasha iyo dareemayaasha Sinomeasure pH, ama isticmaalaya mitirka pH ee benchtop ee deegaanka shaybaadhka ee noocyada kale, ama mitirka pH ee gacanta lagu qabto, pH buffers ayaa laga yaabaa inay kugu habboon yihiin.
Xusay: Haddii aad ku cabbirayso pH muunad ka baxsan 25°C (77°F) cabbir sax ah, tixraac jaantuska ku yaal dhinaca baakadaha cabbirka pH ee heerkulkaas.
