Description

CT****3 pH composite electrode, CT****3C pH composite electrode be make from pH galss electrode and Agcl reference electrode. The body is glass, it's important part of pH meter and measure pH value of the liquid. It be widely used in chemistry, industry, medication and science etc..

• Operation environment

1. Environment temperature : 5 ~ *0℃
2. Environment humidity: ≤*5%

• Maintain and Attention

①　Immerse pH electrode into 3.3N KCL solution for 2 hours when pH                     electrode be used first or didn't use it for long time.
②　Wash the electrode in the distill water clear before using and wipe up.
③　CT****3 pH electrode don't need to append reference solution.
④　CT****3C pH electrode is rechargeable. Need to append 3.3N KCL                     reference solution.
⑤　Don't immerse pH electrode into distill water or the liquid for long                      time when don't using.
⑥　Confect 3.3N KCL solution:

1. Put **6g KCL powder into the ***0ML water without ion.
2. Use a glass stick in the water, swirling it untill the white powder          dissolved.
