style="text-indent:25px">安徽原裝電導(dǎo)率儀承諾守信</p><p> 電導(dǎo)率（conductivity），也稱為導(dǎo)電率：是用來描述物質(zhì)中電荷流動(dòng)難、易程度的參數(shù)，水的導(dǎo)電性即水的電阻的倒數(shù)，通常用它來表示水的純凈度。電導(dǎo)率是物體傳導(dǎo)電流的能力。一、電導(dǎo)率儀的單位電導(dǎo)的基本單位是西門子（S），原來被稱為姆歐，取電阻單位歐姆倒數(shù)之意。因?yàn)殡妼?dǎo)池的幾何形狀影響電導(dǎo)率值，所以標(biāo)準(zhǔn)的測量中用單位S/cm來表示電導(dǎo)率，以補(bǔ)償各種電極尺寸造成的差別。單位電導(dǎo)率（C）簡單的說，是所測電導(dǎo)（G）與電導(dǎo)池常數(shù)(L/A)的乘積。這里的L為兩塊極板之間的液柱長度，A為極板的面積。=ρl=l/σ1、定義：電阻率的倒數(shù)為電導(dǎo)率。σ=1/ρ2、單位:在國際單位制中，電導(dǎo)率的單位是西門子/米，其它單位有：s/cm，us/cm。1S/m=；3、電導(dǎo)率的物理意義：是表示物質(zhì)導(dǎo)電的性能。電導(dǎo)率越大則導(dǎo)電性能越強(qiáng)，反之越小。二、電導(dǎo)率的測量原理將兩塊平行的極板，放到被測溶液中，在極板的兩端加上一定的電勢（通常為正弦波電壓），然后測量極板間流過的電流。根據(jù)歐姆定律，電導(dǎo)率(G)--電阻(R)的倒數(shù)，是由電壓和電流決定的。引起離子在被測溶液中運(yùn)動(dòng)的電場，是由與溶液直接接觸的二個(gè)電極產(chǎn)生的。此對測量電極必須由抗化學(xué)腐蝕的材料制成。實(shí)際中經(jīng)常用到的材料有鈦等。安徽原裝電導(dǎo)率儀承諾守信</p><p
