PR2 Cleaning and Chemical Avoidance
Instructions
The PR2 shaft is made of polycarbonate plastic which is an
exceptionally strong material, and it can withstand bending
forces far in excess of anything likely to be encountered in
practice. However, polycarbonate can develop stress cracking
when exposed to certain chemicals. Such stress cracking greatly
weakens the polycarbonate and may lead to brittle fracture of the
shaft, even at very low stresses.
It is important to follow these guidelines. Failure to observe these
precautions can damage the probe and may invalidate the
warranty.
Clean the probe in use if necessary by wiping with damp
plain paper towels.
Use only clean water to damp the paper. Do not use
chemicals or cleaning agents of any sort in the water.
Never use any chemical solvents or cleaners on the probe,
or near to it. Avoid strong chemical vapours, especially
during probe storage.
Do not immerse the probe in water. If this happens
the probe to dry in warm air for at least 24 hours.
Make sure the probe
