Yuav ua li cas yog txoj kev txij nkawm ntawm acid-base concentration meter?
Acid-base concentration meter ntsuas qhov concentration ntawm cov tshuaj tsis ncaj los ntawm kev ntsuas cov conductivity ntawm cov tshuaj. Nws yog lub npe hu hais tias nyob rau hauv ib tug tej yam qhov kub thiab txias, lub conductivity ntawm cov low-concentration electrolyte sib raug rau cov concentration ntawm cov tshuaj. Thaum qhov kub thiab txias hloov, cov conductivity kuj hloov, piv txwv li, cov concentration ntawm cov tshuaj yog ib tug muaj nuj nqi ntawm conductivity thiab kub.
Nws siv lub conductance electrode sensor rau kev ntsuas (cov khoom siv electrode yog platinum), txhawm rau kom tsis txhob electrode polarization, lub ntsuas hluav taws xob tsim hluav taws xob muaj zog sine yoj teeb liab thiab ntxiv rau lub electrode, thiab tam sim no ntws los ntawm electrode yog proportional. mus rau qhov concentration ntawm cov tshuaj ntsuas. Qhov tam sim no ntws los ntawm cov electrode yog ntsuas los ntawm preamplifier thiab hloov mus rau hauv lub teeb liab voltage, thiab qhov hluav taws xob hluav taws xob muaj kev cuam tshuam txog tus nqi concentration yog tau tom qab qhov kev pab cuam tswj amplification, theem-sensitive nrhiav thiab lim; Lub microprocessor hloov pauv qhov ntsuas kub thiab ntsuas qhov ntsuas qhov ntsuas los ntawm kev hloov pauv, Tom qab kev suav thiab ntsuas qhov kub thiab txias, nws tau hloov dua siab tshiab thiab tso tawm kom pom raws li ntsuas ntsuas tus nqi thiab qhov ntsuas kub ntawm lub sijhawm ntawm 25 degree.
Txoj kev kho ntawm acid-base concentration meter:
1. Thaum tsis siv lub cuab yeej, lub hwj chim yuav tsum raug txiav tawm raws sij hawm, thiab nws yuav tsum muab tso rau hauv qhov chaw huv si, tsis muaj plua plav thiab qhuav.
2. Tom qab txhua qhov kev sim, qhov saum npoo ntawm qhov ntsuas, lub electrode interface ntawm acid-base concentration meter thiab qhov kub thiab txias interface yuav tsum tau wiped huv si thiab khaws cia nyob rau hauv ib tug qhuav lub xeev.
Kev saib xyuas ntawm acid-base concentration meter electrodes:
1. Cov electrodes yuav tsum tau ntxuav tas li kom ntseeg tau tias lawv tsis muaj paug thiab thaiv.
2. Tom qab ntxuav cov electrode txhua zaus, siv cov ntawv lim los txhuam cov dej ntws ntawm cov electrode, thiab muab tso rau hauv lub khob ncig.
3. Thaum tsis siv electrode, nws yuav tsum muab tso rau hauv qhov chaw qhuav thiab tsis muaj plua plav.
