Tsis siv neeg kub them nyiaj txoj cai ntawm acid-base concentration meter
Kev ntsuas lub hauv paus ntsiab lus: Lub ntsuas hluav taws xob siv lub ntsuas hluav taws xob ntsuas hluav taws xob 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 cov electrode, tam sim no ntws los ntawm lub ntsuas hluav taws xob. electrode muaj feem xyuam rau cov concentration ntawm cov ntsuas ntsuas nyob rau hauv kev faib ua feem, tam sim no ntws los ntawm lub electrode yog ntsuas los ntawm lub preamplifier thiab hloov mus rau hauv ib tug voltage teeb liab, thiab lub voltage teeb liab qhia txog tus concentration tus nqi yog tau tom qab kev pab cuam tswj amplification, theem- rhiab nrhiav thiab lim; lub microprocessor hloov cov teeb liab kub thiab cov teeb liab concentration Alternate sampling, tom qab ua hauj lwm thiab kub them nyiaj ua hauj lwm, hloov dua siab tshiab thiab tso tawm kom pom raws li qhov ntsuas concentration tus nqi thiab real-time kub tus nqi ntawm 25 degree.

Lub hauv paus ntsiab lus ntawm kev them nyiaj kub tsis siv neeg: qhov concentration ntawm cov tshuaj ntsuas tsis yog-linearly proportional rau nws cov conductivity, thiab cov conductivity ntawm cov tshuaj hloov vim qhov kub thiab txias, thiab qhov kub thiab txias yuav tsum tau them. Cov yam ntxwv kub ntawm ntau yam kev daws teeb meem sib txawv, thiab nws yog ua los ntawm microprocessor. Cov txheej txheem cuam tshuam tau nrawm thiab raug, paub txog kev ua haujlwm ntawm kev siv nyiaj kub tsis siv neeg.
tus
Lub acid-base concentration meter txais lub hauv paus ntsiab lus ntawm electromagnetic induction, uas zam lub corrosion, muaj kuab paug thiab polarization los ntawm muaj zog corrosive dlaws xws li cov kua qaub thiab alkalis ntawm cov electrodes, thiab muaj peev xwm saib xyuas cov nyhuv regeneration ntawm ion exchanger kom tsis txhob muaj calcium. ntawm lub txaj zoo thiab silica gel ntawm lub txaj tsis zoo, xyuas kom muaj kev nyab xeeb thiab kev lag luam ntawm ion exchangers, thiab tsim nyog rau kev tshawb nrhiav ntau yam muaj zog electrolytes xws li HCI, H2SO4, NaOH, thiab NaCl.
