Digi-Temp & Digi-Temp EZ Liquid Crystal Thermometers These self-adhesive labels consist of a series of temperature sensitive elements containing microencapsulated Thermochromic Liquid Crystal, TLC, coated on a black backing. Each element changes color distinctly as its rated temperature is reached. Thermochromic Liquid Crystals have been used in several common applications including: Forehead Thermometers Fridge Thermometers Nursery Thermometers Aquarium Thermometers Gas Level Indicators Overheat Indicators The technology is like that used in TV and Watch Displays. However, instead of reacting to electrical impulses, they respond to fluctuations in temperature. They can be formulated to react to temperatures between -30°C (-22°F) and 120°C (248°F) and react to changes in temperature as small as 0.1°C (0.2°F). Accurate to up to +/- 1°C if stored and used correctly, they will remain functional for many years. Digi-Temp® color changes are reversible passing through the colors of the spectrum in sequence (Orange, Yellow, Green, and Blue before turning black at a higher temperature. The TLC strips are calibrated so that the indicator that shows green indicates the actual temperature. The color changes are reversible and the reflected colors will be observed in the reverse order upon cooling. Digi-Temp EZ single color changes are reversible meaning that the attained and maintained reflected color will turn black as the temperature is reversed. Thermochromic Single Color Change (EZ) Labels can be ascending or descending, that is, change from black to a color as temperature increases or black to a color as the temperature decreases
