Liquid Crystal Thermometer Strips

Liquid Crystal Thermometers

Windows Change Color for Continuous Visual Monitoring of Surface Temperatures from -22°F TO 248°F (-30°C TO 120°C).

Telatemp reversible liquid crystal thermometers signify the current temperature by the green indication. If green is not visible, the temperature will be midway between the indicators that are illuminated tan and blue. The colors are seen in reverse order as the temperature cools.

These adhesive-backed liquid crystal thermometers have many real-world applications that include room or refrigerator thermometers, body temperatures, optimum processing or operating temperatures, hot warning labels, thermal profiling, etc.

Custom requirements are invited.
