Kuv yuav ua li cas yog tias lub teeb hluav taws xob ntawm pH meter puas lawm?
pH electrode, tseem hu ua pH sojntsuam, pH sensor, lus Askiv lub npe pH electrode lossis pH sensor, yog ib feem ntawm pH meter uas nyob rau hauv kev sib cuag nrog cov khoom yuav tsum tau ntsuas, thiab yog siv los ntsuas lub peev xwm electrode.
Kev ntsuas pH hauv online feem ntau muaj plaub ntu: pH sensor, uas yog pH electrode, pH transmitter, electrode sheath, thiab cable.
Lub ntsiab yog vim li cas rau qhov tawg iav qhov muag teev ntawm cov electrode yog tshwm sim los ntawm sab nraud quab yuam xws li kev sib tsoo thiab extrusion. Lub siab ntawm lub qhov muag hluav taws xob yog feem ntau Tsawg dua lossis sib npaug rau 0.6MPa. Nws yog ib qho uas siv cov electrode ua stirrer thaum ntsuas. Thaum siv, cov txheej txheem ntxuav, ziab, thiab capping yuav tsum tau ceev faj, txwv tsis pub nws yooj yim tawg vim muaj zog ntau dhau. Tom qab nws tawg lawm, cov electrode no kwv yees siv tsis tau, thiab cov electrode yuav tsum tau rov xaiv dua.
Yuav ua li cas tiv thaiv cov electrodes ntawm lub sij hawm zoo tib yam?
1. Cov electrodes yuav tsum tau muab cia rau hauv qhov chaw qhuav ntawm 10 degree thiab 30 degree.
2. Thaum qhov kub thiab txias qis dua -5 degree, lub electrode yuav tawg vim qhov khov ntawm qhov tsis muaj thiab electrolyte.
3. Vim yog vim li cas kev thauj mus los, thaum siv electrodes, nws yog ib qho tsim nyog yuav tsum tau soj ntsuam seb lub rhiab membrane npuas yog ntim nrog cov tshuaj. Yog hais tias muaj npuas nyob rau hauv daim nyias nyias, cov npuas npuas yuav tsum tau maj mam shaken cia ob peb zaug (zoo li tus pas ntsuas kub) ua kom cov npuas npuas hauv cov kua nplaum.
4. Yog tias pH electrode khaws cia rau hauv qhov chaw qhuav, nws yuav tsum tau tsau rau 24 teev ua ntej siv, txwv tsis pub nws yuav nyuaj rau calibrate.
5. Thaum tsis siv lub hau electrode, cov electrode yuav tsum tau muab tso rau hauv cov tshuaj tsis haum, tsis yog hauv dej distilled.
6. Txhua lub electrode yuav tsum tau calibrated ua ntej nws yuav siv tau nrog ib tug pH meter. Yuav tsum muaj ob lub ntsiab lus calibration rau pH electrode, thiab cov txheej txheem buffer tov (pH6.86, pH4.00 los yog pH9.18) yuav tsum tau siv rau calibration.
7. Qhov zaus ntawm calibrating los yog xyuas cov ntsuas electrodes nyob ntawm cov ntawv thov sib txawv (qhov degree ntawm cov av hauv daim ntawv thov, kev tso tawm ntawm cov tshuaj lom neeg, thiab lwm yam).
