Liquid crystals are chemical compounds and mixtures that exhibit the mechanical properties of liquids and the optical characteristics of solids.

Liquid crystals that change color with changes in temperature are known as thermo chromic liquid crystals (TLC's). Scientifically they are identified as Cholestric Liquid Crystals. Micro-encapsulation is the process that primarily protects, stabilizes and makes the liquid easier to use.

Feverscan thermometers are composed of a series of discreet temperature events, each event shows a green color as indicated temperature is attained.

The color changes from tan to green to blue as the temperature increases.

How to use:

• Remove backing. Apply to center of forehead. Skin surface should be clean and dry.
• Read temperature after colors stop changing. Typically 15 seconds.
• GREEN-Correct reading. If GREEN not visible, subtract 1 dgree Fahrenheit from highest lit channel to obtain correct reading.
