溶解氧電極 工業(yè)溶氧電極 溶氧電極 

型號：GR/DO100

北京GR/DO100溶解氧電極現(xiàn)貨供應(yīng)采用極譜式電極，陽電極為Ag/AgCl、陰電極為鉑金（Pt）組成，兩者之間充滿特殊成份的是電解液。由硅橡膠滲透膜包裹于電極四周。測量時，電極間加上675mV的極化電壓,氧滲透過隔膜在陰極消耗,同時等量的氧在陽極產(chǎn)生,這個動態(tài)過程進(jìn)行到兩邊的氧分壓相同時達(dá)到平衡.此時兩電極間的電流與氧分壓成正比,二次表檢測到此電流,再經(jīng)過一系列變換,得到氧濃度和氧含量.同時,NTC(負(fù)溫度系數(shù)熱敏電阻)檢測被測量液的溫度,二次表采樣后進(jìn)行溫度補償,將氧濃度或氧含量折算成25℃時的值。

陰極反應(yīng)：O2+2H2O+4e→4OH

陽極反應(yīng)：4Ag+4Cl-→4AgCl+4e

北京GR/DO100溶解氧電極現(xiàn)貨供應(yīng)溶氧電極可用來測量用來對氧含量會影響反應(yīng)速度、流程效率或環(huán)境的流程進(jìn)行監(jiān)控：如水產(chǎn)養(yǎng)殖、生物反應(yīng)、環(huán)境測試(湖、溪、海洋）、水/廢水處理、葡萄酒生產(chǎn)。 T401ppm型溶解氧電極具有較高的穩(wěn)定性和可靠性，可在惡劣環(huán)境中使用，維護(hù)量也較小。

使用極譜式電極時，校正或測量前要預(yù)熱至少15－30分鐘。

為確保膜的電解液內(nèi)沒有氣泡，ASI膜帽在設(shè)計上要求在裝上膜頭時要排除掉所有液腔內(nèi)的空氣。

膜表面上不能留有任何氣泡，否則它會將氣泡當(dāng)作氧飽和樣品進(jìn)行讀數(shù)。

即使使用的是帶有自動溫度補償?shù)膬x表，也要在接近樣品溶液的溫度下校正電極。

電極應(yīng)在空氣中校正，以空氣作為100%的飽和溶解氧標(biāo)準(zhǔn)點。

由于電極對氧的消耗，探頭表面氧的濃度會瞬間降低，因此測量時要對溶液進(jìn)行攪拌，這很重要。
