® Storage SenTix of the shaft (see figure). At the same time, the level of the reference elec- trolyte must be at least 2 cm above the level of the solution. Reference electrolyte Shaft Junction (Example) Glass membrane Provide approximately the same stirring conditions for measuring as for calibrating.
® SenTix Aging Aging Every pH combination electrode undergoes a natural aging process. With ag- ing, the responding behavior becomes slower and the electrode slope and asymmetry change. Moreover, extreme operating conditions can consider- ably shorten the lifetime of the combination electrode. These are: ...
