In HI8417 the temperature reading is also displayed on the left
LCD.
Note: the electrode should be submerged approximately 4 cm (1½")
into the solution. If the temperature probe is used, it should
be located as close to the pH electrode as possible.
If measurements are taken in different samples successively, it is
recommended that the electrode is rinsed thoroughly for better condi-
tioning and to eliminate cross-contamination of the sample.
For the rinsing process, it is recommended to use a liberal amount of
the next solution to be measured.
Using refillable electrodes
Unscrew the small refill cap to open the refill hole during measure-
ments. After measurement replace the refill hole cap.
