CAUTION
After supplying the KCl solution, make sure that no leakage of KCl solutions occurs.
If so, grounding connections will be made at two points. This may cause unstable readings or
measurement errors.
(4) Install the pH sensor to the holder. Insert the pH sensor in the liquid chamber until the liquid
junction in the sensor reaches the bypass in the liquid chamber and secure the sensor with metal
clamp. If the solution does not pass the bypass, remove the sensor from the solution chamber
and submerge it in a container filled with water.
This prevents the glass electrode from being dry out or KCl solution — flowed out of the liquid
junction — from being crystallized.
