PH仪以及电导率仪

测试的时候直接把电极放到溶液中，读数稳定了就可以了。记得每次都要清洗电极。
PH仪校准方法 
1. 用6.86校正液校正，用温度计测校正液温度并调节温度旋钮至所测温度，后按确认按钮                                                                                                                                          2. 调定位按钮至6.86并确认 
3. 用4.00校正液校正，调斜率按钮校至4.00，后按确认                                                     

4. 调节完毕并将PH仪重新放入饱和KCL溶液中                                                               

注：浸泡的KCL溶液必须是饱和的，同时要求有KCL晶体析出 阳极电泳漆用6.86和9.0的进行校正

电导率仪校准方法                                                                                                               

1. 将电导率仪放入0.01mol/L  KCL溶液中                                                                           

2. 调温度旋钮至所测温度                                                                                                   

3. 同时调节常数至1.0                                                                                                         

4. 调节校正按钮至100
5. 调量程按钮至III档，并与标准参数相对照                                                                       

6. 调常数按钮至标准参数 7. 将量程调回原处
注：用纯水浸泡
