PH METER qhov kev ua tau zoo, ntxiv rau qhov ntsuas nws tus kheej sab nraud cov qauv, thiab kev saib xyuas zoo yog qhov sib cais tsis tau, PH meter cov cuab yeej zoo li no thiab siv ib puag ncig feem ntau yuav tsum tau hu rau cov tshuaj siv tshuaj, yog li ntawd, kev saib xyuas tsim nyog ntau dua.
(1) instrument input end (i.e. composite electrode jack) must maintain clean, electrode plug don't often dial the next, in order to prevent dust and high humidity immersion.
(2) puas electrode taub hau nyias nyias, yog li ntawd, tsis nyuaj thiab kev sib tsoo, tiv thaiv electrode puas.
(3) composite electrode lub taub hau tsis txhob hu rau av, xws li kev tshawb pom ntawm cov kab mob muaj kab mob kho mob paj rwb graze electrode taub hau, los yog nrog 0.1 mol / L dilute hydrochloric acid tu.
(4) puas electrode lub taub hau tawg los yog laus (ntev muab tso rau saum toj ib xyoos), yuav tsum tau pauv tshiab electrode, los yog qeeb teb, txawm yuav ua rau loj ntsuas yuam kev, tus tshiab electrode nyob rau hauv ua ntej koj siv nws koj yuav tsum nyob rau hauv 3 mol / L poov tshuaj chloride. daws 24 h.
(5) nrog rau qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas, kom ntseeg tau qhov kev ntseeg tau ntawm cov tshuaj tsis haum, vim tias cov tshuaj tsis muaj qhov tseeb qis, yuav ua rau qhov tshwm sim ntawm kev ntsuas qhov yuam kev, cov tshuaj tsis tuaj yeem ua rau kev npaj, kev npaj yog txuas rau hauv qab no.
