Kev sib xyaw thiab kev ua haujlwm ntawm cov hluav taws xob sib xyaw hauv cov khoom siv pH
Cov electrode uas sib txuas cov iav electrode thiab siv electrode ntawm pH meter yog hu ua pH meter composite electrode. Lub plhaub hluav taws xob sib xyaw ntawm cov khoom siv pH meter ua los ntawm cov yas yog hu ua lub plhaub yas pH sib xyaw electrode. Composite electrode plhaub ntawm ib qho kev lag luam pH meter ua los ntawm iav yog hu ua iav pH puas electrode. Qhov zoo tshaj plaws ntawm kev lag luam pH meter composite electrodes yog lawv kev koom ua ke thiab siv tau yooj yim.
Cov qauv ntawm kev lag luam pH meter composite electrodes feem ntau muaj cov khoom siv hluav taws xob, cov khoom siv iav, cov khoom siv hluav taws xob sab hauv, cov kev daws teeb meem sab hauv, cov plhaub, cov khoom siv hluav taws xob sab nraud, cov kev daws teeb meem sab nraud, cov kua cuam tshuam, electrode caps, electrode xov hlau, sockets, thiab lwm yam.
⑴ Muaj pH meter composite electrode noob: Nws yog tsim los ntawm melting thiab tshuab lithium iav nrog hydrogen muaj nuj nqi, tsim ib tug kheej kheej, nrog ib tug zaj duab xis thickness txog 0.1-0.2 hli, thiab tus nqi kuj ntawm<250 megaohms (25 ℃).
⑵ Cov iav txhawb lub raj rau cov khoom siv hluav taws xob ntawm cov khoom siv pH ntsuas: Nws yog lub iav raj lub cev uas txhawb nqa pH meter electrode npuas, ua los ntawm cov iav txhuas nrog cov hluav taws xob zoo heev, thiab nws cov coefficient nthuav dav yuav tsum ua raws li cov pH meter electrode npuas iav.
Internal reference electrode ntawm lub industrial pH meter composite electrode yog ib tug silver / silver chloride electrode, uas yog tsuas yog siv los rho tawm lub peev xwm ntawm pH meter electrode. Nws yuav tsum muaj lub peev xwm ruaj khov thiab qhov kub me me coefficient.
(4) Internal reference solution for industrial pH meter composite electrode: Ib qho kev siv sab hauv nrog lub peev xwm xoom ntawm 7 pH, uas yog cov tshuaj sib xyaw ntawm nruab nrab phosphate thiab potassium chloride. Tus nqi pH ntawm lub iav pH meter electrode thiab siv electrode los tsim kom muaj pes tsawg lub peev xwm hauv lub roj teeb feem ntau yog nyob ntawm tus nqi pH ntawm cov tshuaj siv sab hauv thiab cov concentration ntawm chloride ions.
(5) Muaj pH meter composite electrode yas plhaub: pH meter electrode yas plhaub yog lub plhaub uas txhawb cov iav electrode thiab kua interface, thiab muaj cov tshuaj siv sab nraud. Nws yog tsim los ntawm polycarbonate yas nias.
Kev siv hluav taws xob sab nraud ntawm cov khoom siv pH meter composite electrode yog nyiaj / nyiaj chloride electrode, uas muab thiab tswj xyuas cov peev txheej ruaj khov, yuav tsum muaj peev xwm ruaj khov, zoo rov tsim dua tshiab, thiab qis qis coefficient.
(7) Kev siv sab nraud ntawm cov khoom siv hluav taws xob ntawm cov khoom siv ph meter: 3.3mol / L potassium chloride gel electrolyte, uas tsis yooj yim rau plam thiab tsis tas yuav ntxiv.
Cov xuab zeb core kua interface ntawm kev lag luam pH meter composite electrode: Cov kua sib txuas yog qhov sib txuas ntawm cov tshuaj siv sab nraud thiab cov tshuaj ntsuas, thiab yuav tsum muaj kev ruaj khov permeability.
Muaj pH meter composite electrode hlau: Nws yog lub suab qis hlau thaiv cov hlau, nrog rau cov tub ntxhais sab hauv txuas nrog cov khoom siv hluav taws xob sab hauv thiab cov ntaub thaiv npog txuas nrog rau sab nraud siv electrode.
