ʻO DDS-1702 Portable Conductivity Meter kahi mea hana i hoʻohana ʻia no ke ana ʻana o ka conductivity o ka wai wai i loko o ka hale hana.Hoʻohana nui ʻia ia i ka ʻoihana petrochemical, bio-medicine, ka mālama ʻana i ka wai, ka nānā ʻana i ke kaiapuni, ka mining a me ka hoʻoheheʻe ʻana a me nā ʻoihana ʻē aʻe a me nā keʻena kolepa junior a me nā keʻena noiʻi.Inā hoʻolako ʻia me ka electrode conductivity me ka hoʻomau kūpono, hiki ke hoʻohana ʻia e ana i ka conductivity o ka wai maʻemaʻe a i ʻole ka wai ultra-maʻemaʻe i loko o ka semiconductor uila a i ʻole ka mana nuklea a me nā mea kanu mana.

ʻO ka hoʻokōhe ana o ka hiki o ka wai ke hele i ke kahe uila.Pili pololei kēia hiki i ka ʻike o nā ion i ka wai
1. Loaʻa kēia mau ion conductive mai nā paʻakai hoʻoheheʻe ʻia a me nā mea inorganic e like me ka alkalis, chlorides, sulfides a me nā pūhui carbonate.
2. ʻO nā pūhui e hoʻoheheʻe ʻia i loko o nā ion ua ʻike ʻia hoʻi he electrolytes.Pēlā nō, ʻo ka liʻiliʻi o nā ion i loko o ka wai, ʻoi aku ka liʻiliʻi o ka conductive.Hiki ke hana i ka wai i hoʻoheheʻe ʻia ma ke ʻano he insulator ma muli o kona haʻahaʻa loa (inā ʻaʻole haʻahaʻa) ka waiwai conductivity.ʻO ka wai kai, ma kekahi ʻaoʻao, he kiʻekiʻe loa ka conductivity.
Hoʻoholo nā Ion i ka uila ma muli o kā lākou uku maikaʻi a maikaʻi ʻole
Ke hoʻoheheʻe ʻia nā electrolytes i loko o ka wai, ua hoʻokaʻawale lākou i nā ʻāpana hoʻoili maikaʻi (cation) a me nā ʻāpana ʻino (anion).I ka wā e māhele ai nā mea i hoʻoheheʻe ʻia i loko o ka wai, e mau ana ka hoʻopaʻa ʻana o kēlā me kēia kauā maikaʻi a me ka ʻole.ʻO ia hoʻi, ʻoiai ke piʻi aʻe ka conductivity o ka wai me nā ion i hoʻohui ʻia, ʻaʻole mau ka uila 2
Alakaʻi Conductivity Theory
ʻO ka Conductivity/Resistivity kahi hoʻohālikelike analytical i hoʻohana nui ʻia no ka nānā ʻana i ka hoʻomaʻemaʻe wai, ka nānā ʻana i ka reverse osmosis, nā kaʻina hana hoʻomaʻemaʻe, ka hoʻomalu ʻana i nā kaʻina hana kemika, a me ka wai ʻino ʻoihana.ʻO nā hopena hilinaʻi no kēia mau noi like ʻole e pili ana i ke koho ʻana i ka sensor conductivity kūpono.ʻO kā mākou alakaʻi hoʻomaikaʻi ʻana he hōʻike piha a me ka mea hana hoʻomaʻamaʻa e pili ana i nā ʻumi makahiki o ke alakaʻi ʻoihana i kēia ana.
