* Sensors na Haɗaɗɗiya: Auna canjin aiki na maganin electrolyte akan hulɗa da mai nazari.

5. Amfanin Sensors na Electrochemical:

* Babban hankali da zaɓi.
* Lokacin amsawa mai sauri.
* Ikon yin aiki a cikin matakan ruwa da gas.
* Ability don aiki a cikin turbid ko samfurori masu launi.
* Sau da yawa šaukuwa kuma dace da ainihin-lokaci bincike.

6. Iyakance:

* Na'urori masu auna firikwensin na iya zama gurbatacce ko guba ta hanyar gurɓatawa, suna shafar aikinsu.
* Juyawa a cikin yuwuwar wutar lantarki na iya haifar da kurakurai.
* Wasu suna buƙatar daidaitawa lokaci-lokaci don kiyaye daidaito.

Gabaɗaya, aikin firikwensin lantarki ya dogara da ƙayyadaddun ƙira, kayan da aka yi amfani da su, da kuma yanayin amsawar electrochemical na mai binciken manufa. Faɗin aikace-aikacen su ya ta'allaka ne daga sa ido kan muhalli da binciken likita zuwa tabbatar da ingancin abinci da ƙari.
