WARNING:
When inspecting and replacing O-rings, always wear gloves, a lab coat, and safety goggles.
If you accidentally touch a contaminant, immediately rinse the contaminated area thoroughly un-
der running water, and then disinfect the area.
Seek medical assistance if necessary.

curate, which may negatively affect the measurement values.
