2.對鍍鉑黑的電極,使用前可浸泡在去離子水中,以防止鉑黑的惰化.
3.鉑黑鍍層脫落或退色時,則鉑黑必須重新電鍍,以保證所測數據的準確性.
4.電極出廠時候在電極上標注的電導池常數緊供參考,檢驗所標電導池常數準確與否,可根據被測溶液的濃度和溫度,查得相應標準溶液的電導率值C,然后根據實測的電導儀顯示值P進行電導池常數K的計算:K=C/P.<\/span> <\/p> <\/span> <\/p> | 型號<\/span><\/span> <\/p> <\/td> | 溶液濃度<\/span><\/span> <\/p> <\/td> | 溶液溫度<\/span><\/span> <\/p> <\/td> | 電導率<\/span>C<\/span>值<\/span>ms/cm<\/span> <\/p> <\/td> <\/tr> | DJS-0.1<\/span> <\/p> <\/td> | 0.001mol/L KCL<\/span> <\/p> <\/td> | 25<\/span> <\/p> 30<\/span> <\/p> <\/td> | 1.46<\/span>8<\/span>×10-4<\/sup><\/span> <\/p> <\/span>1.64<\/span>×10-4<\/sup><\/span> <\/p> <\/td> <\/tr> | 260.DJS-1<\/span> <\/p> <\/td> | 0.01mol/L KCL<\/span> <\/p> <\/td> | 25<\/span> <\/p> 30<\/span> <\/p> <\/td> | 1.413<\/span>×10-3<\/sup><\/span> <\/p> 1.552<\/span>×10-3<\/sup><\/span> <\/p> <\/td> <\/tr> | DJS-10<\/span> <\/p> <\/td> | 0.1mol/L KCL<\/span> <\/p> <\/td> | 25<\/span> <\/p> 30<\/span> <\/p> <\/td> | 1.2<\/span>8<\/span>×10-2<\/sup><\/span> <\/p> <\/span>1.414<\/span>×10-2<\/sup><\/span> <\/p> <\/td> <\/tr> <\/tbody> <\/table> <\/div> <\/div> <\/div> <\/div> <\/ul> <\/div> <\/div> <\/div> <\/div> <\/div><\/div>
