class="NyNewsdetail_title">DDS-307實(shí)驗室電導率儀的工作原理、構成和使用注意事項講解</h1> <div id="h83oqh3" class="NyNewsdetail_tips">更新時(shí)間：2023-04-18 點(diǎn)擊次數：2150</div> <div id="mqxxiol" class="NyNewsdetail_con"> <div>　　實(shí)驗室電導率儀是一種用來(lái)測量溶液中離子電導率的儀器。這種儀器廣泛應用于化學(xué)、生物、環(huán)境等領(lǐng)域的實(shí)驗室中，因為它可以幫助研究人員快速、準確地了解不同類(lèi)型的溶液的電性質(zhì)。<br /> </div><div>　　DDS-307實(shí)驗室電導率儀的工作原理基于歐姆定律，即當電流通過(guò)一個(gè)導體時(shí)，導體內部會(huì )產(chǎn)生電場(chǎng)，并且電場(chǎng)的強度與電流密度成正比。在溶液中，由于存在游離的離子，因此它也具有導電能力。<br /> </div><div>　　DDS-307實(shí)驗室電導率儀主要由以下幾個(gè)組件構成：<br /> </div><div>　　電極：電極通常由兩個(gè)平板電極和一個(gè)電極支架組成。平板電極通常由不銹鋼或純鉑制成，其表面光滑，以確保測量精度。<br /> </div><div>　　電源：電源用于提供測量電流。這種電流通常非常小，通常低于1毫安。<br /> </div><div>　　電壓計：電壓計用于測量在兩個(gè)電極之間施加的電場(chǎng)強度。<br /> </div><div>　　顯示器：顯示器通常用于顯示測量結果，例如電導率、電阻率等。<br /> </div><div>　　為了進(jìn)行電導率測量，首先需要將溶液樣品倒入一個(gè)電導池中。然后將電極插入電導池中，并確保電極充分接觸溶液。在準備就緒后，打開(kāi)電源并調節電流強度，然后通過(guò)電壓計測量電場(chǎng)強度。，讀取顯示器上的電導率值。<br /> </div><div>　　在使用DDS-307實(shí)驗室電導率儀時(shí)需要注意以下幾點(diǎn)：<br /> </div><div>　　使用前應該清洗電極以去除任何可能影響電導率測量的雜質(zhì)。<br /> </div><div>　　在進(jìn)行電導率測量前需要校準儀器，以確保測量結果的準確性。<br /> </div><div>　　在進(jìn)行測量時(shí)應避免過(guò)度攪拌溶液，因為這可能會(huì )破壞電極表面的平整度。<br /> </div> </div> <div id="9o3izfc" class="ly_PrevNext"> <ul> <li>上一篇：<a
