Pre- pare the electrode for measuring as follows: Open the refilling opening for the reference electrolyte solution. Depend- ing on the model, the stopper of the refilling opening is an elastomer stop- per or a slider.
- Page 6 Storage SenTix trolyte in the electrode must be at least 2 cm above the level of the solu- tion. Reference electrolyte Shaft Junction (Example) Glass membrane Provide approximately the same stirring conditions for measuring as for calibrating. Note Prevent contact of the pH membrane to the beaker bottom to avoid scratches on the pH membrane.

SenTix Aging Note During longer storing periods, salt sediments may develop on the watering cap. They do not affect the measuring characteristics and can easily be re- moved with deionized water when the electrode is put into operation again. Aging Every pH electrode undergoes a natural aging process. - Page 8 Maintenance and cleaning SenTix Cleaning Remove water-soluble contamination by rinsing with deionized water. Re- move other contamination as follows: Contamination Cleaning procedure Fat and oil Rinse with water containing household wash- ing-up liquid Lime and hydroxide deposits Rinse with citric acid (10 % by weight) Proteins Immerse in pepsin cleaning solution PEP/pH for approx.
