型號:GR/DO100
北京GR/DO100溶解氧電極現貨供應采用極譜式電極,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生,這個動態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,再經過一系列變換,得到氧濃度和氧含量.同時,NTC(負溫度系數熱敏電阻)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:O2+2H2O+4e→4OH
陽極反應:4Ag+4Cl-→4AgCl+4e
北京GR/DO100溶解氧電極現貨供應溶氧電極可用來測量用來對氧含量會影響反應速度、流程效率或環境的流程進行監控:如水產養殖、生物反應、環境測試(湖、溪、海洋)、水/廢水處理、葡萄酒生產。 T401ppm型溶解氧電極具有較高的穩定性和可靠性,可在惡劣環境中使用,維護量也較小。
使用極譜式電極時,校正或測量前要預熱至少15-30分鐘。
為確保膜的電解液內沒有氣泡,ASI膜帽在設計上要求在裝上膜頭時要排除掉所有液腔內的空氣。
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。
即使使用的是帶有自動溫度補償的儀表,也要在接近樣品溶液的溫度下校正電極。
電極應在空氣中校正,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。
