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(cè)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(jiǎn)單的說，是所測(cè)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(cè)量原理將兩塊平行的極板，放到被測(cè)溶液中，在極板的兩端加上一定的電勢(shì)（通常為正弦波電壓），然后測(cè)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(cè)溶液中運(yùn)動(dòng)的電場(chǎng)，是由與溶液直接接觸的二個(gè)電極產(chǎn)生的。此對(duì)測(cè)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。北京廠家電導(dǎo)率儀</p><div

電池隨著使用時(shí)間的增加，會(huì)逐漸老化，其老化的主要原因正是電池極表面發(fā)生硫化、腐蝕，活性材料脫落，無法再進(jìn)行有效的化學(xué)反應(yīng)，這是絕大部分電池?zé)o法繼續(xù)使用的主要原因。電導(dǎo)測(cè)試儀的工作原理就是通過測(cè)量極板表面的情況，判定其化學(xué)反應(yīng)能力，并通過極板的變化來推斷電池容量的變化，從而判定電池的健康狀況。電導(dǎo)測(cè)試儀所進(jìn)行的測(cè)試工作就是以電池在線測(cè)得的實(shí)際電導(dǎo)值與電池完好時(shí)的標(biāo)準(zhǔn)電導(dǎo)值進(jìn)行比較，如果差異大到一定程度，就可以判定該電池需要更換了。實(shí)踐證明，電導(dǎo)儀的測(cè)試結(jié)果與用1/2的CCA值放電的測(cè)試結(jié)果是吻合的，充分說明了電導(dǎo)儀測(cè)試的科學(xué)性、準(zhǔn)確性。

）三、電導(dǎo)率儀的電導(dǎo)電極的種類、用途電導(dǎo)電極一般分為二電極式、多電極式兩種類型。1、二電極式電導(dǎo)電極是目前使用多的電導(dǎo)電極類型，實(shí)驗(yàn)式二電極式電導(dǎo)電極的結(jié)構(gòu)，是將二片鉑片燒結(jié)在二平行玻璃片上，或圓形玻璃管的內(nèi)壁上，調(diào)節(jié)鉑片的面積和距離，就可以制成不同常數(shù)值的電導(dǎo)電極。通常有K=1、K=5、K=10等類型。而在線電導(dǎo)率儀上使用的二電極式電導(dǎo)電極，常制成圓柱形對(duì)稱的電極。當(dāng)K=1時(shí)，常采用石墨，當(dāng)K=、，材料可以是不銹鋼或鈦合金。2、多電極式電導(dǎo)電極一般在支持體上有幾個(gè)環(huán)狀的電極，通過環(huán)狀電極的串聯(lián)和并聯(lián)的不同組合，可以制成不同常數(shù)的電導(dǎo)電極。環(huán)狀電極的材料可以是石墨、不銹鋼、鈦合金和鉑金。3、電導(dǎo)電極還有四電極類型和電磁式類型四電極電導(dǎo)電極的優(yōu)點(diǎn)，是可以避免電極極化帶來的測(cè)量誤差，在國外的實(shí)驗(yàn)式和在線式電導(dǎo)率儀上較多使用。電磁式電導(dǎo)電極的特點(diǎn)，是適宜于測(cè)量高電導(dǎo)率的溶液，一般用于工業(yè)電導(dǎo)率儀中，或利用其測(cè)量原理制成單組分的濃度計(jì)，如鹽酸濃度計(jì)、硝酸濃度計(jì)等。四、電導(dǎo)率電極常數(shù)的測(cè)定、校準(zhǔn)根據(jù)公式K=S/G，電極常數(shù)K可以通過測(cè)量電導(dǎo)電極，在一定濃度的KCL溶液中的電導(dǎo)G來求得，此時(shí)KCL溶液的電導(dǎo)率S是已知的。安徽高級(jí)電導(dǎo)率儀</p><p
