                                      sc200水質分析儀的特性

                                       
                                      1、pH計的特點 pH電極上的玻璃隨著時間推移會逐漸老化,梯度(單位pH值變化所引起的電極輸出電位的變化值)惡化,花費較長時間才能達到穩定電位。一般電極的使用壽命,可達兩年。另外,溫度對老化也有較大影響,100℃下貯存幾周的老化程度相當于室溫下貯存一年的老化程度。 sc200水質分析儀具有高精度、高可靠性、安裝及維護方便等優點,同時對污染也較敏感,需要經常標定,一般每隔一個到一個半月標定一次,每兩年更換一次電極。

                                      2、溶氧儀的特點 溶氧儀具有安裝方便,標定周期長(3~4個月),對其他物質不敏感等特點,并且能監測隔膜和探頭內電解質的使用情況,一般每一至三年更換一次電解質和隔膜。 

                                      COM252型溶氧變送器屬智能化儀表,帶有HART或Profibus通訊協議,還具有自診斷功能,當發生故障時,會顯示故障代碼,提示維護人員故障所在,通過查維護手冊找出解決故障的辦法,大大降低了維護時間和工作量。



                                      尊敬的客戶:
