C. Precautions
1. The electrode used for the first or long set without re-use, the electrode bulb and the sand
core, immersed in the 3NKCL solution activated eight hours.
2. The electrode plug should be kept clean and dry.
3. Electrode reference solution is the 3NKCL solution.
4. Measurement should be avoided staggered pollution between solutions, so as not to affect the
accuracy of measurement.
5. Electrode blub or sand core is defiled which will make PTS decline, slow response. So, it should
be based on the characteristics of the pollutant, adapted to the cleaning solution, the electrode
performance recovery.
6. The electrode should not be long-term immersed in acid chloride solution.
7. Electrode when in use, the ceramic sand core and liquid outlet rubber ring should be removed,
in order to make salt bridge solution to maintain a certain velocity.
