Ib lub ntsuas hluav taws xob muaj peev xwm ntsuas tus nqi ntawm cov khoom tawg tag nrho (TDS) hauv cov tshuaj, hauv cov khoom ntawm ib lab (ppm) lossis milligrams ib liter. Tus qauv kev sib raug zoo ntawm TDS kev ntsuas ntawm kev daws teeb meem thiab kev ntsuas kev ntsuas yog: TDS (ppm) x 2=Conductivity (µS)
Peb tuaj yeem ntsuas qhov ntsuas hluav taws xob li cas?
Kev coj ua tau ntsuas nrog kev sojntsuam thiab ib lub ntsuas. Qhov hluav taws xob yog siv ntawm ob lub electrodes nyob rau hauv ib qho kev sojntsuam rau hauv cov qauv dej. Kev poob hauv qhov hluav taws xob tshwm sim los ntawm qhov tsis kam ntawm cov dej yog siv los xam cov conductivity ib centimeter.
Koj ntsuas qhov kev coj ua hauv kev sim li cas?
Xaiv cov hluav taws xob conductivity los ntawm qhov tsis kam, ntev thiab thaj tsam ntawm tam sim no. Lub resistivity yog muab raws li p=RA / l qhov p yog qhov resistivity, R yog qhov tsis kam, A yog qhov chaw thiab l yog qhov ntev. Cov conductivity yog s=1 / pqhov twg yog qhov kev coj ua.
Koj ua li cas hloov tsis kam mus rau conductivity?
Rau hluav taws xob conductivity Siemens ib meter yog siv, cim los ntawm S / m. Conductivity yog inverse ntawm resistivity. Yog hais tias peb sawv cev conductivity los ntawm σ(greek sigma) thiab resistivity los ntawm ρ(greek rho) lawv cov kev sib raug yog muab los ntawm: σ=1 / ρ.
Yuav ua li cas cov kua ua kua hauv chav kawm 8?
Hluav taws xob conductivity ntawm cov kua tuaj yeem kuaj tau los ntawm kev ua haujlwm yooj yim ntawm kev noj cov kua, xws li kua txiv qaub, hauv ib lub thawv, ntxig electrodes hauv nws, txuas ob lub electrodes rau lub terminals ntawm lub roj teeb nrog lub teeb (LED) nruab nrab ntawm lawv. Lub teeb ci ntsa iab, qhia tias cov kua txiv qaub yog cov khoom siv hluav taws xob.
