Kho thiab Calibration ntawm Industrial pH Meter
(1) Thaum qhov kub thiab txias sib txawv heev, pH meter yuav tsum tau nruab nrog qhov kub thiab txias kom tshem tawm qhov cuam tshuam ntawm qhov ntsuas kub ntawm lub ntsuas pH. Nyob rau lub caij ntuj no, ntxiv dag zog rau lub rwb thaiv tsev ntawm pH meter thiab nws cov kav dej kom ntseeg tau tias qhov kub thiab txias yog tswj nyob rau hauv thaj tsam ntawm 17-21 degree . Kev ua haujlwm ruaj khov ntawm pH meter nyob rau lub caij ntuj sov yog qhov zoo dua li lub caij ntuj no, thiab qhov kub thiab txias tau tswj tau qis dua 45 degree.
(2) Thaum kho lub ntsuas pH, qhov ntsuas kub yuav tsum tau khaws cia ntawm 25 degree. Thaum teeb tsa qhov kub thiab txias, nws yuav tsum ua raws li qhov ntsuas kub ntawm cov txheej txheem nruab nrab.
(3) Ua tib zoo saib xyuas cov txheej txheem tsim khoom, xws li kev tsim khoom tsis zoo, kev tsim khoom raug kaw, thiab lwm yam, nws yuav tsum tau kuaj xyuas pH ntsuas hauv lub sijhawm.
① Tshawb xyuas seb puas muaj cov kua hauv lub xov tooj ntawm tes. Yog tias tsis muaj kua, cov txheej txheem nruab nrab tuaj yeem txuas rau electrode vim dryness, thiab nws tsis tuaj yeem ntsuas thaum nws rov ua dua.
②Txawm hais tias muaj qhov kub thiab txias lossis crystallization hauv cov txheej txheem nruab nrab, yog tias muaj, pH meter yuav tsum tau muab tshem tawm rau kev tiv thaiv kev kho mob, thiab cov iav electrode yuav tsum tsis txhob muab tso rau pem hauv ntej.
③ Lub pH meter disassembled tom qab nres tsheb yuav tsum tau muab tso rau hauv pH4 tsis muaj tshuaj uas muaj KCl rau pH electrode, kom nws tuaj yeem ua haujlwm ntawm lub iav qhov muag teev thiab cov kua dej sib txuas tib lub sijhawm. Yog tias tsis muaj cov xwm txheej no, lub taub hau pH tuaj yeem muab tso rau hauv cov dej ntshiab rau anaerobic cia, thiab nws yuav tsum tsis txhob muab tso rau hauv huab cua yam tsis muaj kev tiv thaiv.
(4) Raws li qhov xwm txheej tshwj xeeb, nws tsis yog qhov teeb meem loj rau calibrate ib hlis ib zaug, thiab calibrate tsawg li tsawg tau. Lub fwj loj tshaj plaws ntawm pH meter yog lub neej kev pab cuam, tshwj xeeb tshaj yog cov siv electrode, uas yooj yim qias neeg thiab lom. Yog hais tias qhov siv electrode puas lawm, lub pH meter yog qhov yooj yim scrapped.
(5) Cov conductivity ntawm kev ntsuas ntsuas cuam tshuam qhov tseeb ntawm qhov ntsuas. Cov khoom siv pH feem ntau xav kom cov conductivity ntawm cov ntsuas ntsuas tsis tsawg dua 50 μS / cm. Tsis tas li ntawd, nws muaj ntau yam ua rau kev ua haujlwm. Kev saib xyuas tshwj xeeb yuav tsum tau them rau cov haujlwm ua haujlwm uas muaj cov sulfur thiab alkali. Yog tias tsim nyog, cia lub chaw soj nstuam ua piv txwv los txiav txim siab qhov cuam tshuam ntawm pH meter.
