由二個(gè)電極組成的測(cè)量電極被稱為科爾勞施（Kohlrausch）電極。電導(dǎo)率的測(cè)量需兩個(gè)參數(shù)：一個(gè)是溶液的電導(dǎo)，另一個(gè)是溶液中L/A的幾何關(guān)系，電導(dǎo)可以通過電流、電壓的測(cè)量得到。電導(dǎo)率常數(shù)K=L/A其中：A-測(cè)量電極的有效極板，L-兩極板的距離。這一值則被稱為電極常數(shù)。在電極間存在均勻電場(chǎng)的情況下,電極常數(shù)可以通過幾何尺寸算出。當(dāng)兩個(gè)面積為1cm2的方形極板，之間相隔1cm組成電極時(shí)，此電極的常數(shù)K=1cm-1。如果用此對(duì)電極測(cè)得電導(dǎo)值G=1000μS，則被測(cè)溶液的電導(dǎo)率K=1000μS/cm。一般情況下，電極常形成部分非均勻電場(chǎng)。此時(shí)，電極常數(shù)必須用標(biāo)準(zhǔn)溶液進(jìn)行確定。標(biāo)準(zhǔn)溶液一般都使用KCl（氯化鉀）溶液，這是因?yàn)镵Cl的電導(dǎo)率的不同的溫度和濃度情況下非常穩(wěn)定，準(zhǔn)確。mol/l的KCl溶液在25℃時(shí)電導(dǎo)率為。所謂不均勻電場(chǎng)（也稱作雜散場(chǎng)，漏泄場(chǎng)）沒有常數(shù)，而是與離子的種類和濃度有關(guān)。因此，一個(gè)純雜散場(chǎng)電極是復(fù)雜的電極，它通過一次校準(zhǔn)，不能滿足寬的測(cè)量范圍的需要。（不均勻電場(chǎng)：是電場(chǎng)區(qū)域內(nèi)電場(chǎng)強(qiáng)度的大小和方向，隨空間坐標(biāo)而變的電場(chǎng)。反之，電場(chǎng)強(qiáng)度的大小和方向與坐標(biāo)無關(guān)的電場(chǎng)，被稱為均勻電場(chǎng)。</p><p> 由于測(cè)量溶液的濃度和溫度不同，以及測(cè)量?jī)x器的精度和頻率也不同，電導(dǎo)電極常數(shù)K有時(shí)會(huì)出現(xiàn)較大的誤差，使用一段時(shí)間后，電極常數(shù)也可能會(huì)有變化，因此，新購的電導(dǎo)率電極，以及使用一段時(shí)間后的電導(dǎo)率電極，電極常數(shù)應(yīng)重新測(cè)量標(biāo)定。電導(dǎo)電極常數(shù)測(cè)量時(shí)，應(yīng)注意以下幾點(diǎn)：1、測(cè)量時(shí)應(yīng)采用配套使用的電導(dǎo)率儀，不要采用其它型號(hào)的電導(dǎo)率儀。2、測(cè)量電極常數(shù)的KCL溶液的溫度，以接近實(shí)際被測(cè)溶液的溫度為好。3、測(cè)量電極常數(shù)的KCL溶液的濃度，以接近實(shí)際被測(cè)溶液的濃度為好。五、電導(dǎo)率儀使用時(shí)的注意事項(xiàng)1、在測(cè)量純水或超純水時(shí)，為了避免測(cè)量值的漂移現(xiàn)象，建議采用密封槽，在密封狀態(tài)下的進(jìn)行流動(dòng)測(cè)量，如采用燒杯取樣測(cè)量，則會(huì)產(chǎn)生較大的誤差。2、因溫度補(bǔ)償是采用固定的2%的溫度系數(shù)，所以，超、高純水的測(cè)量，盡量采用溫度不補(bǔ)償方式進(jìn)行，測(cè)量后查表。3、電極插頭座應(yīng)防止受潮，儀表應(yīng)安置于干燥環(huán)境，避免因?yàn)樗螢R射或受潮，引起儀表的漏電或測(cè)量誤差。4、測(cè)量電極是精密部件，不可以分解，不可以改變電極形狀和尺寸，且不可以用強(qiáng)酸、堿清洗，以免改變電極常數(shù)，而影響儀表測(cè)量的準(zhǔn)確性。5、為確保測(cè)量的精度，電極使用前，應(yīng)用小于(或去離子水)沖洗二次。</p><div

經(jīng)過國際上大量的實(shí)驗(yàn)數(shù)據(jù)表明，電導(dǎo)值與電池容量呈很好的線形關(guān)系。對(duì)于同一種電池，隨著使用后電池容量的下降，該電池的電導(dǎo)值也會(huì)下降，這樣的一個(gè)線形關(guān)系正是電導(dǎo)儀能夠正確判定電池健康情況的基礎(chǔ)。正因?yàn)槿绱?，國際電氣和電子工程師協(xié)會(huì)（IEEE）正式把電導(dǎo)測(cè)試法作為檢測(cè)鉛酸蓄電池的檢測(cè)標(biāo)準(zhǔn)之一，在IEEE標(biāo)準(zhǔn)1118-1996的第15頁，明確指出：電池電導(dǎo)的測(cè)量是將已知頻率和振幅的交流電壓加到電池的兩端，然后測(cè)量所產(chǎn)生的電流。交流電導(dǎo)值就是與交流電壓同相的交流電流分量與交流電壓的比值。明顯的電導(dǎo)值的變化（下降大于20%）就意味著電池性能的變化。北京直銷電導(dǎo)率儀報(bào)價(jià)</p><p
