6.0 Probe Care
6.1 Bluelab pH Probe care
pH probes DO NOT last forever. They age through normal use and will eventually
fail. The lifetime of a pH probe depends on the environment it is used in and the way
that it is treated. To receive a long life from your Bluelab pH Probe, please ensure you
follow the guide below.
pH probes contain glass and are therefore FRAGILE. With good care, they will
give a long service life.

DO NOT let the pH probe tip dry. IF IT DRIES IT DIES!
DO NOT bend the probe; this will break its internal glass tube.
DO NOT knock the probe; this will break its internal glass tube or external glass bulb.
DO NOT plunge a cold pH probe into a hot liquid, or a hot probe into cold liquid.
Sudden temperature changes can crack the glass and permanently damage the probe.
DO NOT immerse in oils, proteins or suspended solids that will leave a coating on the glass bulb.
DO NOT ‘kink’ or bend the lead sharply.
DO NOT attempt to lengthen the lead on the pH probe.
DO NOT wet the BNC connector at the end of the lead.
Always remove pH probe storage cap before use
Grip the top of the cap and gently twist the base one
rotation clockwise to loosen slightly.
Next slowly slide the cap off the pH probe. DO NOT
completely remove the base of the cap from the top
of the cap.
Store the storage cap in a safe place.
