Taking care of the "liquid crystal" thermal sensing sheet
The thermal sensing sheet can be damaged easily.
Follow a few simple precautions to prolong its usefulness.
The material is in the form of a kind of paint on a clear piece
of plastic sheet.
The clear plastic covers and protects the side (the
front) where the color appears. The back side is unprotected
and is susceptible to scratches and peeling.
The back and cut edges of the sheet will stick to a lot of things,
including other liquid crystal sheets, many kinds of plastic,
and paper, when stored for a while.
likely to stick to something. Keeping the sheets separated by
Storing the sheets and pieces separated by pieces of
waxed paper will prevent sticking. We strongly recommend this.
The thermal sensing sheet can be wetted or even immersed in water,
but may turn gray if soaked for a long time. When you finish an
activity that involves wetting the sheet, blot it dry and
then let dry in air. If a sample turns gray, it may recover when aired out
for a few days. If not, let us know.
The sensor sheet should not be heated above 115 F.
