6: Hardware Data Sheets and Instructions
Use Warnings
• Handle with care. Dropping the probe may cause permanent damage.
• Gently remove the plastic cover from the SMA connector before use.
• Pulling the SMA connector away from the probe when removing the plastic cover could damage the
probe.

Sterilization Methods Tested on Oxygen Probes
The following sterilization methods have been tested for use with oxygen probes. The results of each
sterilization method are listed to in the right column of the table:
Method Results
Autoclaving (steam sterilization 30 minutes or
more at 121 °C)
Each cycle decreases signal by more than 50%.
Recalibration is necessary; lifetime of probe is 6- 8
cycles.
Gamma Radiation No effect.
