LIFE
EXPECTANCY
The life expectancy of the sensor is expressed in
%-hours as follows:
[Oxygen
Concentration (%) x
Exposure Time (hours)]
Accordingly, the life of the Apogee Oxygen Sensor is 900,000
%-hours or approximately 10 years of continuous use for the
Soil Sensor and 5 years of continuous use for the
Fast-Response Sensor at 21% oxygen at 20 C.
STORAGE
The life of the sensor can be extended by storage
at a lower temperature. For example a sensor stored at 0 C
will have a life expectancy approximately twice that of a
sensor stored at 20 C.
The absolute minimum storage temperature is
-20 C. Below that temperature the electrolyte will freeze.
Maximum storage temperature is
60 C. |
