Masensa a CS6710C Fluoride Ion Electrode Rs485 Modbus 4-20ma

Kufotokozera Kwachidule:

Fluoride Ion-Selective Electrode (ISE) ndi sensa yapadera kwambiri komanso yodalirika ya electrochemical yopangidwira kuyeza mwachindunji potentiometric ya ntchito ya fluoride ion (F⁻) mu mayankho amadzi. Imadziwika ndi kusankha kwake kwapadera ndipo ndi chida chodziwika bwino mu chemistry yowunikira, kuyang'anira zachilengedwe, kuwongolera njira zamafakitale, komanso thanzi la anthu, makamaka pokonza bwino fluoridation m'madzi akumwa.
Pakati pa elekitirodi ndi nembanemba yozindikira ya solid-state yomwe nthawi zambiri imapangidwa ndi kristalo imodzi ya lanthanum fluoride (LaF₃). Akakumana ndi yankho, ma ion a fluoride ochokera mu chitsanzo amalumikizana ndi lattice ya kristalo, ndikupanga mphamvu yamagetsi yoyezeka kudutsa nembanemba. Mphamvu iyi, yoyesedwa motsutsana ndi elekitirodi yamkati, imakhala yofanana ndi ntchito ya ion ya fluoride malinga ndi Nernst equation. Chofunika kwambiri pakuyeza molondola ndikuwonjezera Total Ionic Strength Adjustment Buffer (TISAB). Yankho ili limagwira ntchito zitatu zofunika: limasunga pH yokhazikika (nthawi zambiri pafupifupi 5-6), limakonza maziko a ionic kuti lipewe zotsatira za matrix, ndipo lili ndi zinthu zomangira kuti zitulutse ma ion a fluoride omangiriridwa ndi ma cations osokoneza monga aluminiyamu (Al³⁺) kapena chitsulo (Fe³⁺).
