Sensing Element Maintenance
Storage:
The Oxygen Sensing Element may be stored in its package
until its first use.
It is recommended that the sensing element be stored with the
threaded nose piece in the downward position. This insures
that the electrolyte remains in contact with the membrane for
extended periods of storage. Sensor life may be extended by
storing the sensing element in a refrigerator at 40ºF to 50ºF
(4°C to 10°C). Do not freeze the sensor or sensing element.
Replacement:
Order Model Number PS-6524 Oxygen Sensing Element
Replacement.
