Vim li cas tus nqi zaub ntawm PH meter transmitter hloov pauv ntau npaum li cas?
Tus nqi tso saib ntawm online PH meter transmitter tsis ruaj khov thiab hloov pauv ntau dhau, thiab nws ua tsis tiav 2 teev tom qab kev ntsuas cov qauv ua kua thaum nws thawj zaug siv. Qhov tseeb tshwm sim yog tias PH tus nqi ntawm qhov ntsuas nruab nrab yog nyob nruab nrab ntawm 6.8 thiab 7.2. Thaum tus nqi PH yog 6.8, tus nqi tso tawm ntawm lub transmitter hloov ntawm 5.9. Thaum tus nqi PH yog 7.2, qhov pom tus nqi ntawm lub transmitter poob ntawm 11, thiab tom qab ntawd poob rau 10, thiab tom qab ntawd maj mam poob. Qhov tshwm sim no tsis tshwm sim tom qab hloov lub transmitter tshiab.
Qhov teeb meem uas tus nqi tso saib ntawm online PH meter transmitter hloov pauv tau zoo heev yog qhov tsis tshua muaj, thiab tsis muaj ntau yam teeb meem nrog cov khoom siv PH ntsuas, uas qee zaus tshwm sim. Koj puas xav pom seb koj puas muaj kev sojntsuam tshiab? Txheeb xyuas qhov impedance nrog kev sojntsuam tshiab. Tsis tau hloov qhov kev sojntsuam, xyuas tus choj ntsev. * Seb puas yuav txiav txim siab hloov qhov kev sojntsuam tom qab. Tej zaum yuav muaj kev sib txuas xoob, yog li nruj lub davhlau ya nyob twg.
Lus Cim: ntsev choj, tom qab cov ntaub ntawv siv electrode tau muab tso rau hauv cov tshuaj ntsuas, ib qho me me ntawm cov tshuaj KCl seeps los ntawm cov porous ceramics. Nws yog txuas nrog cov ntaub ntawv siv hluav taws xob sab hauv thiab ntsuas kev ntsuas sab nraud, uas ua lub luag haujlwm ntawm tus choj rau hluav taws xob tiv tauj, yog li nws yog hu ua choj choj. Kev xau ceev ntawm E ntsev choj tov muaj kev cuam tshuam zoo rau cov kua dej sib txuas: qhov qeeb qeeb ua rau cov kua dej sib txuas tsis ruaj khov; Tsis tas li ntawd, yog tias lub siab ntawm cov ntsuas ntsuas tau nce thiab qhov tso tawm qeeb qeeb, cov tshuaj ntsuas tuaj yeem nkag mus rau hauv cov khoom siv electrode, ua rau acidity meter ua tsis tiav.
Ntawm pH6.8 ~ 7.2, tus naj npawb ntawm hydrogen ions hloov nyob ib ncig ntawm 4, uas tsis muaj zog heev thaum hloov mus rau mv teeb liab. Yog hais tias lub amplifier yog amplified raws li qhov piv no thiab ib tug sib txawv tsis yog siv, nws tej zaum yuav qhia tau hais tias -2 los yog 16.
Ua ke nrog qhov tseeb tias qhov txhaum ploj tom qab koj hloov lub transmitter, kuv qhov kev tsom xam yog yuam kev. Yog tias koj tsis hloov qhov tsis nyob rau lub sijhawm ntawd, pH yuav zaum dhia, uas tshwm sim. 7.2 tsis? Feem ntau, 4.0, 6.86 (los yog 7. yuav ntau dua 2.0.
Piv txwv tias pH ntawm cov tshuaj tsis hloov pauv, feem ntau yog vim li cas vim li cas cov txiaj ntsig ntawm online PH meter transmitter fluctuates heev thiab cov kev nyeem feem ntau dhia yog:
1. Cov av hauv av tsis zoo, nrog rau cov kav dej ntawm lub transmitter thiab electrode.
Qee lub sij hawm tuav cov cable tshwj xeeb los ntawm tes los yog kov lub plhaub hlau ntawm 253 yuav hloov pH nyeem ntawv zoo heev.
&2. Daim ntawv electrode tau teeb tsa tsis raug, uas zoo ib yam li koj hais.
Asymmetrical asymmetric kev sib txuas thiab symmetrical symmetrical kev sib txuas;
3. Qhov nqes hav ntawm qhov kawg calibration yog tsawg dhau
