Sensor Replacement:
The sensor is an oxygen driven fuel cell. At the end of its typical life of 12 - 15
months, the output of the cell will fall to zero in less than a day. If the sensor will no
longer recalibrate, it should be replaced. It is recommended that sensors be replaced
regularly at 12 month intervals.

• do not expose open end of sensor housing to liquids, particulates, grease etc.
• do not touch top of sensor within open end of sensor housing
• do not allow vacuum grease to coat open end of sensor
• do not expose sensor housing to sudden mechanical or electrical shocks
• do not expose sensor to temperature extremes below 0°C or above 45°C
• sensors may be stored for up to one year in a refrigerator at 7°C. DO NOT
FREEZE.
