Nā Mea ʻIke Electrode Ion Fluoride CS6710C Rs485 Modbus 4-20ma

Wehewehe Pōkole:

ʻO ka Fluoride Ion-Selective Electrode (ISE) kahi sensor electrochemical kūikawā a hilinaʻi hoʻi i hoʻolālā ʻia no ke ana ʻana o ka potentiometric pololei o ka hana fluoride ion (F⁻) i loko o nā hopena wai. Ua kaulana ia no kona koho kūikawā a he mea hana maʻamau ia i ka kemika analytical, ka nānā ʻana i ke kaiapuni, ka kaohi ʻana i nā kaʻina hana ʻoihana, a me ke olakino lehulehu, ʻoi aku ka maikaʻi no ka hoʻomaikaʻi ʻana i ka fluoridation i ka wai inu.
ʻO ke kikowaena o ka electrode he membrane ʻike paʻa i haku ʻia me kahi kristal hoʻokahi o ka lanthanum fluoride (LaF₃). Ke hoʻopili ʻia me kahi hopena, launa pū nā ion fluoride mai ka laʻana me ka lattice kristal, e hana ana i kahi hiki ke ana ʻia ma waena o ka membrane. ʻO kēia hiki, i ana ʻia e kūʻē i kahi electrode kuhikuhi kūloko, ua like ia me ka logarithmically i ka hana ion fluoride e like me ka Nernst equation. ʻO kahi koi koʻikoʻi no ke ana pololei ʻana ʻo ia ka hoʻohui ʻana o kahi Total Ionic Strength Adjustment Buffer (TISAB). Hana kēia hopena i ʻekolu mau hana koʻikoʻi: mālama ia i kahi pH mau (ma kahi o 5-6), hoʻopaʻa i ka ionic background e pale i nā hopena matrix, a loaʻa nā mea hoʻohuihui e hoʻokuʻu i nā ion fluoride i hoʻopaʻa ʻia e nā cations interfering e like me ka alumini (Al³⁺) a i ʻole ka hao (Fe³⁺).
