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)過程進行到兩邊的氧分壓相同時達到平衡.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,否則它會將氣泡當作氧飽和樣品進行讀數(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%的飽和溶解氧標準點。
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行攪拌,這很重要。
