Yuav ua li cas xaiv volumetric txoj kev thiab coulomb txoj kev rau kab ya raws kuaj?

Thaum cov dej ntsiab lus ntawm cov qauv yuav tsum tau ntsuas yog qhov tsawg, Karl Fischer Coulometric noo ntsuas ntsuas yog siv, qhov kev tshawb nrhiav ceev tsis yog ceev xwb, tab sis kuj yog cov ntaub ntawv sib luag zoo heev; Qhov tshwm sim yog qhov zoo tagnrho; Yog li thaum cov dej ntsiab lus ntawm cov qauv yuav tsum ntsuas qis dua 1000ppm, siv Karl Fischer Coulomb noo noo meter, thiab thaum tus qauv yuav tsum tau ntsuas muaj ntau tshaj 1000 ppm noo noo, siv Karl Fischer volumetric txoj kev noo noo meter.
