Liquid Crystal Thermometer Strip Product Information; Product Information. Some of the principles of the thermometer were known to Greek philosophers of two thousand years ago. The results are displayed via color changes in the cholesteric liquid material the liquid crystal thermometer is made from. While the measurement is not as precise as a laser thermometer or a traditional thermometer which is immersed in the liquid, the liquid crystal thermometer produces a result that has sufficient accuracy for reactions that must be kept in a certain temperature range, rather than a specific target temperature. The TLC strips are calibrated so that the indicator that shows green indicates the actual temperature. Why? Popular liquid crystal applications include medical devices, forehead, aquarium and room thermometers, promotional pieces and advertising applications. 60 to 89°C ±2°C 90 to 120°C ±3°C In other words, they show characteristics of both!
