MAINTENANCE AND RECALIBRATION
Visual inspection of the Teflon membrane should be made periodically to verify that the oxygen path is free from
obstruction, as shown below. Avoid placing sharp objects inside the sensor opening, as the membrane can easily be
punctured.
Life expectancy of the oxygen sensor on the MO-200 oxygen meter is approximately five years of continuous use in 20.95 %
oxygen and 20 C. Lifetime can be lengthened by storing the sensor in low oxygen environments and/or in cold temperatures
(e.g., fridge) when not in use. Note that for long periods of storage in low oxygen, the sensor will need a few hours in ambient
air before the response time returns to normal.
Sensor calibration can be conducted periodically and should be determined by the level of measurement accuracy required
for the application.
