MAINTENANCE
The following actions will keep the probe in good working
condition:
Always keep the pH glass bulb wet by using the plastic
bottle to protect and store the probe. You can also store
it in a KCl solution. Never use distilled or de-ionized
water for storage.
Always rinse the pH probe in de-ionized water before
using.
Never touch or rub the glass bulb tip.
This probe is designed with a fiber junction. To prolong
the life of the probe, clean the probe monthly by
immersing it in a cleaning solution for a minimum of 30
minutes. After cleaning, rinse with tap water and
recalibrate with the meter.
To further prolong the life of the probe, extend the fiber
junction and cut off the dirty, used portion. The
extendable fiber reference junction is used to eliminate
the reading errors from a clogged junction.
