9.3 Probe Care and Maintenance
Under typical operating conditions, the DO probe should last for several years . Proper
care and maintenance will help you receive the maximum probe life and ensure more accurate
readings.
Since any deposits on the membrane surface act as a barrier to oxygen diffusing through the
membrane, the membrane must be cleaned at regular intervals to assure maximum reliability.
After using the probe, rinse the probe in clean water and wipe it with a soft cloth or paper to
avoid any hardening of deposits. If growth develops on the probe, use a disinfecting chemical
to clean.
NOTE
Although the membrane is strong and not easily damaged, wipe it gently while cleaning it. If
the membrane is damaged or torn, the probe will no longer function.
There are no special probe storage requirements.
