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..
1. Environment temperature : 5 ~ *0
℃
2. Environment humidity:
≤*5%
①　Immerse pH electrode into 3.3N KCL solution for 2 hours
when pH
                  Â
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
                  Â
reference solution.
⑤　Don't immerse pH electrode into distill water or the liquid
for long
                   Â
time when don't using.
⑥　Confect 3.3N KCL solution:
- Put **6g KCL powder into the ***0ML water without ion.
- Use a glass stick in the water, swirling it untill the white
powder        Â
dissolved.
