- Page 2 INE-PHS-3E 2016 ADVICE: Read this instruction carefully before operating the meter. The meter should be re-tested by metrological department when it is used for over one year. The meter can't be used until it is up to standard. The warranty of the glass PH electrode is one year. The electrode should be replaced in time after one year no matter whether it is used or not, since the performance of it will be influenced.

There are often chemical reagents in ambient surrounds, so necessary maintenance can guarantee the meter's normal working. 1) The input end of the meter (electrode socket 6) must be kept dry and clean. When the...
- Page 12 INE-PHS-3E 2016 Notes: 1:Tetrachloro-methane, trichloroethylent, furnaidine etc. can't be selected as detergent, because they will dissolve polycarbonate resin, the shell of the electrode is made of polycarbonate resin, glass bulb will easily be polluted if the shell is dissolved. And the electrode will lose effectiveness. Combination electrode can't be used to measure the above solution, either.
