Reversible Color Changing Thermometer , Thermochromic Liquid
Crystal PET Temperature Strips
Accuracy : ±1 ℃
Temperature range :22～36 ℃
Material : PET
Size :20*50 mm
Principle : Liquid crystal heat sensitive color change
Note : Keep it in shady and cool
Valid date : 2 years
Usage : Measure the temperature.
The color changing thermometer’s temperature-sensitive elements
contain TLC (thermochromic liquid crystal)molecules that are very
sensitive to temperature and change position / twist in relation to
changes in temperature. This change in molecular structure affects
the wavelengths of light that are absorbed and reflected by the
liquid crystals, resulting in an apparent change in the color of
each temperature event.
When the rated temperature of an indicator is reached the TLC
molecules twist slightly causing the TLC substance to absorb the
red and blue portions of the visible light and reflect the green
part. This causes the temperature event to appear green. When the
temperature decreases, the molecules begin to twist in the opposite
direction, and the TLC reflect a different portion of the spectrum.
We guarantee the thermometer’s accuracy for 12 months from the date
