Use and maintenance

1.Soak
and clean the electrode surface with water before use. Various methods
are available for determination.pH/mVCoupled with calomel electrode or
silver chloride, the electrode is inserted directly into the sample and
read when the potential is stable.

2.In
situ determination of soil, sediment, etc. should be carefully, so as
not to deform the end, rough surface, temporary use can be immersed in
water, long-term dry in the box.

3.After
the electrode is used for a long time, surface oxide film or adsorbent,
