DDG-2090 series ntawm cov microcomputer-boofer muaj kev tswj hwm yog precision meters rau kev ntsuasntawm conductivity los yog kev tawm tsam ntawm kev daws teeb meem. Nrog ua tiav cov haujlwm, kev ua haujlwm ruaj khov, kev ua haujlwm yooj yim thiab
Lwm qhov zoo, lawv yog cov khoom zoo tshaj plaws rau kev ntsuas ntsuas thiab tswj.
Qhov zoo ntawm cov ntsuas no suav nrog: LCD zaub nrog lub teeb rov qab thiab cov teeb meem; nws ua nws xwbnyiaj hli tuag; cais 4 ~ 20ma kev tso zis tam sim no; ob tug relay tswj; kho tau qeeb; ceeb toom nrog
sab saud thiab qis dua qhov chaw; Lub hwj chim-down nco thiab ntau dua kaum xyoo kev cia ntaub ntawv tsis muaj roj teeb thaub qab roj teeb.
Raws li qhov ntau ntawm resistivity ntawm cov dej coj ua piv txwv, cov electrode nrog K = 0.01, 0.1,1.0 lossis 10 yuav siv tau los ntawm kev txaus-dhau, kev zij teb chaws, flanged lossis cov yeeb nkab txhim kho.

Conductivity yog kev ntsuas ntawm dej lub peev xwm kom dhau hluav taws xob ntws. Lub peev xwm no ncaj qha ntsig txog kev xav txog e / ions hauv dej
1. Cov kev coj ua no los ntawm cov ntsev ua thiab cov ntaub ntawv inorganic xws li alkalis, chlorides, sulfides thiab cov pa roj carbon monoxide
2. Qhov sib xyaw uas yaj tau rau hauv Eల ions kuj tseem hu ua electrolytes 40. Qhov ntau tshaj plaws uas muaj, qhov siab dua ntawm cov dej. Ib yam li ntawd, lub me dua eons uas nyob hauv dej, qhov tsawg dua nws yog. Distilled lossis deionized dej tuaj yeem ua raws li insulator vim nws qhov tsawg heev (yog tias tsis negligible). Hiav txwv dej, ntawm qhov tod tes, muaj kev coj ua zoo heev.
Ions kev hluav taws xob ua rau lawv cov nqi tsis zoo thiab tsis zoo
Thaum electrolytes yaj hauv dej, lawv faib rau hauv qhov raug them siab (cation) thiab tsis zoo (anion) hais. Raws li cov tshuaj yeeb yaj kiab sib cais hauv dej, qhov ntau ntawm txhua qhov zoo thiab tsis zoo them nqi. Qhov no txhais tau tias txawm tias qhov kev coj ua ntawm cov dej ntxiv nrog ntxiv ions, nws tseem nyob hauv nruab nrab ntawm nruab nrab 2
Kev Qhia Cov Lus Qhia
Conduction / resistivity yog ib tug dav siv Analytical parameter rau cov tshuaj ntsuam xyuas osmosis, kev soj ntsuam ntawm cov txheej txheem ntxuav, tswj cov txheej txheem tshuaj lom neeg, thiab hauv kev siv tshuaj khib nyiab. Cov kev thov txhim khu Peb phau ntawv qhia txog kev ua haujlwm yog ib qho kev siv thiab kev qhia ua haujlwm raws li xyoo xyoo ntawm kev ua kev lag luam hauv qhov ntsuas kev lag luam no.
