Mea ʻIke Alakaʻi CS3732

Wehewehe Pōkole:

ʻO ka electrode kahi sensor kumu i hoʻolālā ʻia e ana i ka hiki o kahi hopena wai e alakaʻi i ke au uila, kahi e pili pono ana me kona nui o nā ion i hoʻoheheʻe ʻia. He mea nui kēia palena koʻikoʻi no ka loiloi ʻana i ka maʻemaʻe o ka wai, ka kaohi ʻana i nā kaʻina hana kemika, a me ka nānā ʻana i ka mālama ʻana i ke kaiapuni ma nā ʻoihana e like me nā lāʻau lapaʻau, ka hana mana, ka meaʻai a me ka mea inu, a me ka mālama ʻana i ka wai ʻino.
ʻO ke kikowaena o ka electrode he cell ana i loaʻa ma ka liʻiliʻi he ʻelua mau mea alakaʻi. Ke hoʻopili ʻia kahi au hoʻololi, hoʻopau nā ion i loko o ka hopena i ke kaapuni ma waena o kēia mau mea. Ana ʻia ka conductance hopena a, me ke kūpaʻa geometric o ke cell (cell constant, K), hoʻohana ʻia e helu i ka conductivity. Hoʻohui pinepine ʻia nā electrodes hou me kahi sensor mahana (maʻamau he Pt100 a i ʻole Pt1000 RTD) no ka uku ʻakomi, ʻoiai ʻo ka conductivity e hilinaʻi nui ʻia i ka mahana. ʻO nā hoʻolālā maʻamau e komo pū me nā cell ʻelua-pole no ka hoʻohana maʻamau a me nā cell ʻehā-pole (a i ʻole ʻehā-electrode), e hoʻohana ana i nā apo au a me nā voltage kaʻawale e hōʻemi i nā hopena polarization a hoʻonui i ka laulā ana, ʻoi aku hoʻi i nā noi conductivity kiʻekiʻe.
