Glass electrode protection bottle
To prevent the glass electrode from becoming dry, the PHP-31 sensor probe is equipped with a glass
electrode protection bottle which contains the phthalate pH standard solution. Remove the protection
bottle before measuring. Reinstall the protection bottle after measurement.
1. Removing the glass electrode protection bottle
1-1. Hold the sensor probe upright so as not to spill the
standard solution in the protection bottle. Turn the
protection bottle counterclockwise while pressing the
cap.
1-2. Slide the cap to take it out from the sensor probe as shown in the

2. Installing the glass electrode protection bottle
2-1. Install the protection bottle to the sensor probe in the reverse order of

the protection bottle. Turn the protection bottle clockwise while pressing
the cap.
2-3. After installing the protection bottle, push in the sensor probe until its tip hits the bottom of
the protection bottle.
Note: * When installing or removing the glass electrode protection bottle, pay attention not to spill the
standard solution in the bottle. If the standard solution comes in contact with the skin (hand),
immediately wash the contaminated skin with running water. If the solution gets into the
eyes, immediately rinse with water and consult a doctor.
