Yog tias kev nyeem ntawv tsis ruaj khov, yuav tsum tau ntsuas pH meter ntau npaum li cas?
Kev nyeem pH meter tsis raug. Yuav ua li cas npaum li cas acidity meter yuav tsum calibrated? Kev nyeem ntawv tsis raug tuaj yeem raug ntaus nqi rau ob qho laj thawj: thaum lub sijhawm ua haujlwm thiab kev saib xyuas ntawm pH electrode. 1, Kev soj ntsuam ntxaws ntawm pH meter electrodes: 1. Puas yog nws ntsuas ua ntej ntsuas; Yog tias qhov calibration tsis zoo ib zaug, nws tuaj yeem rov ua dua. Xa mus rau 3-point calibration nyob rau hauv phau ntawv ntawm cov cuab yeej digital. Yuav ua li cas yuav tsum tau ua rau qhov thib peb point calibration ntawm pH meter? Yog tias calibration tsis ua tau, xav txog kev hloov cov electrode. 2. Electrode npuas muaj paug thiab yuav tsum tau muab ntxuav kom zoo: Yog tias cov tshuaj ntsuam xyuas muaj cov tshuaj uas ua rau muaj cov kab mob rhiab heev los yog thaiv cov kua ua kua, ua rau electrode passivation, txoj kab nqes yuav txo qis thiab cov ntawv nyeem yuav tsis raug. Yog tias qhov tshwm sim no tshwm sim, cov electrode yuav tsum tau muab ntxuav nrog cov tshuaj tsim nyog raws li qhov xwm txheej ntawm cov pa phem kom rov qab los ntawm nws lub xeev qub. Cov kauj ruam tu tuaj yeem xa mus rau lub vev xaib raug cai saum toj no. 3. Ua ntej muab cov electrode tso rau hauv txhua qhov kev sim tshuaj, nws yuav tsum tau ntxuav nrog dej distilled thiab cov nplaum yuav tsum tau ua tib zoo tshem tawm nrog cov ntawv nqus dej kom tsis txhob muaj kev sib kis thiab dilution ntawm cov tshuaj ntsuam xyuas, uas yuav ua rau kev ntsuas thiab ntsuas tsis raug. 2, Kev soj ntsuam yooj yim: 1. Lub pH meter sojntsuam yog qias neeg thiab yuav tsum tau ntxuav. 2. Kev xoob xoob xoob 3, kev laus ntawm pH meter 4, kev hloov pauv loj hauv cov kua ntsuas 3. Qhov laj thawj tseem ceeb yog vim li cas cov ions hauv cov tshuaj me me dhau, ua rau cov ntawv nyeem tsis ruaj khov, xws li cov dej ntshiab. Tau kawg, nws kuj tseem yuav muaj teeb meem nrog lub ntsuas 1. Lub pH meter tsis tau ntxuav kom huv si thiab muaj cov residual reagents 2. Muaj cov tshuaj tiv thaiv hauv cov tshuaj 3. Cov tshuaj tsis tau shaken zoo 4. ntau npaum li cas yuav tsum tus acidity meter yuav calibrated? Nov yog qhov sib txawv ntawm seb koj puas siv hauv kev lag luam lossis hauv chav kuaj. 1. Yog hais tias nws yog siv nyob rau hauv kev lag luam mus txuas ntxiv ntsuas kev daws teeb meem, tsis tas yuav tsum tau calibration. Yog tias nws raug tshem tawm ntawm qhov ntim thawj zaug thiab rov nruab dua, nws yuav tsum tau rov ua dua lossis ntsuas dua. 2. Lub chaw soj nstuam siv lub ntsuas pH, uas yuav tsum tau muaj qhov tseeb. Tau kawg, txhua qhov kev sim koj ua yog txawv, yog li nws yuav tsum tau rov ua dua ua ntej txhua qhov kev siv.
